Multitenancy in WebLogic Server provides a sharable infrastructure for use by multiple organizations. These organizations are a conceptual grouping of your own choosing, which you can think of as tenants. By allowing one domain to support multiple tenants, Weblogic Server Multitenant improves density and achieves a more efficient use of resources while eliminating the hurdles typically present when trying to share multiple applications: runtime cross-application impact, security differences, data co-mingling, and administrative challenges.
WebLogic Server Multitenant provides resource isolation within domain partitions, an administrative and runtime slice of a WebLogic domain that is dedicated to running application instances and related resources for a tenant. Domain partitions achieve greater density by allowing application instances and related resources to share the domain, WebLogic Server itself, the Java virtual machine, and the operating system while isolating tenant-specific application data, configuration, and runtime traffic.
WebLogic Server MT enables an end to end multitenant infrastructure, including multitenancy from the load balancer to the middle tier and cache tier, and to the database tier. WebLogic Server MT extends the Oracle WebLogic Server Enterprise Edition and Oracle WebLogic Suite products, and includes the following components:
Oracle WebLogic Server MT, which enables consolidation of applications into fewer domains (by allowing partitions within domains) while maintaining secure isolation
WebLogic MT extensions to Java SE Advanced, which enables memory, CPU and I/O isolation, monitoring, and management for applications within a JVM
Oracle WebLogic Coherence Enterprise Edition to Grid Edition option, which enables consolidation of caches into fewer Oracle Coherence clusters while maintaining secure isolation
Oracle Traffic Director which provides WebLogic Server MT-aware and fully integrated tenant-aware local load balancing
See Using WebLogic Server Multitenant for additional information.
To support multitenancy, new WLST commands have been added to WebLogic Server 12.2.1 and existing commands have been modified to support new arguments for multitenancy environments.
The following WLST commands have been added for multitenancy:
importPartition—Imports a domain partition from a partition archive.
exportPartition—Exports a domain partition to a partition archive.
startPartitionWait—Starts a domain partition and waits until the partition has started.
migrateResourceGroup—Migrates a domain partition resource group from one target to another target.
The following arguments have been added to existing WLST commands to support multitenancy:
The resourceGroup, resourceGroupTemplate, and partition arguments have been added to the deploy command. Use these to specify the resource group, resource group template, and partition to which a deployment is scoped.
The resourceGroupTemplate, partition, and removePlanOverride arguments have been added to the redeploy command. Use these to specify the resource group template and partition to which the redeployment is scoped, and to specify whether or not the previous plan override at the resource group level should be removed.
The resourceGroupTemplate and partition arguments have been added to the undeploy command. Use these to specify the resource group template and partition to which the deployment is scoped.
The resourceGroupTemplate, partition, and removePlanOverride arguments have been added to the updateApplication command. Use these to specify the resource group template and partition to which the new deployment is scoped, and to specify whether or not the previous plan override at the resource group level should be removed.
The resourceGroup, resourceGroupTemplate, and partition arguments have been added to the distributeApplication command. Use these to specify the resource group, resource group template, and partition to which the copied deployment bundle is scoped.
The partition argument has been added to the startApplication and stopApplication commands. Use this argument to specify the partition to which the deployment is scoped.
The partition argument has been added to the exportDiagnosticDataFromServer command. Use this argument to specify the partition from which diagnostics data will be retrieved.
The partition argument has been added to the saveDiagnosticImageCaptureFile and saveDiagnosticImageCaptureEntry File commands. Use this argument to specify the partition from which the image or image entry will be retrieved.
The partition argument has been added to the captureAndSaveDiagnosticImage command. Use this argument to specify the partition from which the image will be retrieved.
The partition argument is also supported for the following new WLST diagnostic commands. Use this argument to restrain the scope of the diagnostic command to a particular partition within a domain:
activateDebugPatch
deactivateDebugPatches
exportHarvestedTimeSeriesData
exportHarvestedTimeSeriesDataOffline
getAvailableDiagnosticDataAccessornames
purgeCapturedImages
For information about these and other new WLST commands, see WLST.
Using WebLogic Server Multitenant, you can deploy applications and libraries to resource groups templates and resource groups at the domain and partition levels. You can perform deployment operations to these scopes using the new attributes added to existing deployment clients. The following deployment clients support multitenant application deployment:
weblogic.Deployer
WLST deployment commands
JSR-88 API for deployment
JMX Deployment API
WLDeploy ant task
Maven goals for deployment
WebLogic Server Administration Console
Fusion Middleware Control
For more information, see "Deploying Applications" in Using WebLogic Server Multitenant and "Deploying Applications to Resource Groups and Templates" in Deploying Applications to Oracle WebLogic Server.
Additional multitenant deployment features include:
You can use partition-specific deployment plans to customize any application deployed to a resource group template or resource group within a partition. Partition-specific deployment plans are specified at the resource group level within a partition, not at the partition level. When WebLogic Server applies a partition-specific deployment plan to a specified application, the changes prescribed by the plan affect only the application deployment within that partition.
To configure partition-specific application deployment plans, use the redeploy or updateApplication WLST commands. The new WLST options resourceGroupTemplate and partition identify the scope of the application deployment, and the existing WLST options planPath and appName identify the location of the partition-specific deployment plan and the name of the application deployment to modify.
For more information, see "Using Partition-Specific Deployment Plans" in Using WebLogic Server Multitenant.
WebLogic Server 12.2.1 supports concurrent deployment operations across multiple edit sessions. Concurrent deployment allows different partition administrators to deploy applications at the same time, without one administrator having to wait for another administrator's application to complete the deployment process. Concurrent deployment improves performance and prevents administrators from being blocked by other administrators. Concurrent deployment occurs automatically; there are no attributes to configure.
To support multitenancy, JNDI will be partition-aware and provide partition isolation internally. Partition-aware JNDI includes the following features:
Partition-scoped and domain-scoped global JNDI resources—There will be one global JNDI tree for every partition and domain on a node. For example, when deploying an EJB to multiple partitions and domains, the EJB's JNDI name is bound to the global JNDI tree for each partition and domain. When looking up the JNDI name, the JNDI tree that is used depends on the scope of the lookup (partition or domain).
Object-based partition association—When a JNDI context is created within a domain partition, the context object sticks to the partition namespace so that all subsequent JNDI operations are done within the context of the partition.
Cross-partition access—Partition JNDI resources can be accessed from remote standalone Java code using the WebLogic Server client, or by code that resides in a remote WebLogic Server instance. They can also be accessed from another partition on the same server.
Clustered JNDI—The JNDI tree that represents a cluster appears to the client as a single global tree. The tree containing cluster-wide services is replicated across each WebLogic Server instance or partition in the cluster.
Foreign JNDI—You can use foreign JNDI to access another partition whether it is local or remote. By setting up a foreign JNDI provider with the properties of the other partitions, you can look up and use an object that exists outside of the partition.
New provider URL patterns—For local access across partitions, the following new provider URL patterns have been introduced:
local://?partitionName=DOMAIN creates the context on the domain.
local://?partitionName=partitionName creates the context on the specified partition.
Partition JNDI resource lifecycle—Partition JNDI resources are maintained based on the partition lifecycle. When a partition is created and started, the partition JNDI tree is created with the partition root node and becomes available. When the partition is shut down, the partition JNDI tree is deleted.
Partition information binding—When initializing the partition tree, partition information is bound to the partition global JNDI tree. Therefore, you can obtain the partition information of the context by looking up:
weblogic.partitionName, which returns the context-based partition's partition name or "Domain" if it is a domain.
weblogic.partitionID, which returns the current partition's partition ID or "0" if it is a domain.
For more information, see "Configuring and Programming JNDI" in Using WebLogic Server Multitenant.
To support multitenancy and partitions, the Weblogic Security Service includes the following new features in release 12.2.1:
Multiple active realms
To provide isolation of the security configuration and metadata, WebLogic Server now supports the ability to have multiple active security realms in a domain. Support for multiple active realms enables per-partition configuration for realm-based services by allowing each partition to execute against a different realm. Partitions may also share a security realm, which may be appropriate when the security configuration between two partitions does not require isolation.
Identity domains
An identity domain is a logical name space for users and groups, typically representing a discrete set of users and groups in a physical store. Identity domains are used to identify the users associated with particular partitions.
Partition-aware security services
Partition-aware security services contain context about the partition in which they execute so that, for example, they can control access to a resource based on the partition to which the resource belongs. Partition-aware services are also identity domain aware.
To support partition-aware security services, WebLogic Server adds several new predicates that can be used in security policies to scope access at the partition level.
For more information, see "Configuring Security" in Using WebLogic Server Multitenant.
Partition-specific Work Managers provide fairness of thread usage and prioritization of work requests among partitions that share the same WebLogic Server instance.
Partition Work Managers:
Allow system administrators to set thread usage policies among partitions and configure customized QoS levels.
Allow partition administrators to configure Work Manager policies for their partitions.
Support the prioritization of thread usage by work requests from various partitions.
Ensure the fairness in thread resource usage among partitions.
For more information, see "Configuring Partition Work Managers" in Using WebLogic Server Multitenant.
The WebLogic Diagnostics Framework (WLDF) provides the following partition scope diagnostic capabilities:
Partition scope logging
Partition scope debugging
Partition scope log file and diagnostic data access
Monitoring of partition resources
Partition scope application instrumentation
Partition scope diagnostic image capture
For information, see "Monitoring and Debugging Partitions" in Using WebLogic Server Multitenant.
Oracle WebLogic Server Continuous Availability provides an integrated solution for building maximum availability architectures (MAA) that span data centers across distributed geographical locations. Integrated components include Oracle WebLogic Server, Oracle Coherence, Oracle Traffic Director, Oracle SiteGuard, and Oracle Database. The major benefits of this integrated solution are faster failover or switchover, increased overall application availability, data integrity, reduced human error and risk, recovery of work, and local access of real-time data.
The key features in Continuous Availability include:
Automated cross-domain transaction recovery— Provides automatic recovery of XA transactions across an entire domain, or across an entire site with servers running in a different domain or at a different site.
Zero Downtime Patching—Provides an automated mechanism to orchestrate the rollout of patches while avoiding downtime or loss of sessions.
WebLogic Server Multitenant live resource group migration— Provides the ability to migrate partition resource groups that are running from one cluster/server to another within a domain without impacting the application users.
Coherence federated caching—Replicates cache data asynchronously across multiple geographically distributed clusters.
Coherence GoldenGate HotCache—Detects and reflects database changes in cache in real time.
Oracle Traffic Director—Routes HTTP, HTTPS, and TCP traffic to application servers and web servers on the network.
Oracle Site Guard—Enables administrators to automate complete site switchover or failover.
For more information about the features in Continuous Availability and the supported MAA architectures, see Continuous Availability for Oracle WebLogic Server.
Oracle WebLogic Server 12.2.1 is a fully compatible implementation of the Java Platform, Enterprise Edition (Java EE) Version 7.0. Java EE 7 enables developers to make use of the latest innovations in the Java Enterprise APIs, which include new programming models, as well as consolidating, enhancing, and in some cases simplifying existing specifications.
The Java EE 7 APIs and related capabilities simplify development of server applications accessed by "rich" clients using lightweight web-based protocols such as REST, WebSocket, and Server-Sent Events. Improvements to development tooling and open source support expand developer choices and simplify creation of development environments.
New Java EE 7 support updates provided in WebLogic Server 12.2.1 are described in the following sections:
JMS 2.0 Support for Simplified JMS Application Development (JSR 343)
Clustering and High Availability Support for WebSocket 1.1 Applications
WebLogic Server 12.2.1 adds support of a Batch Processing Runtime for the Java EE 7 Platform (JSR 352), which provides support for defining, implementing, and running batch jobs.
The batch runtime in WebLogic Server uses a data source, also known as the JobRepository, and a managed executor service to execute asynchronous batch jobs. The executor service processes the jobs and the JobRepository data source stores the status of current and past jobs. The default batch runtime in each WebLogic domain can be used without any configuration using the Derby demo database. For environments that use an enterprise-level database schema, you can configure a dedicated JobRepository data source and executor service for each WebLogic domain.
For more information about configuring and managing the batch runtime, see "Using the Batch Runtime" in Administering Server Environments for Oracle WebLogic Server.
WebLogic Server 12.2.1 adds support of the Concurrency Utilities for Java EE 1.0 (JSR 236), which is a standard API for providing asynchronous capabilities to Java EE application components, such as servlets and EJBs.
WebLogic Server provides concurrency capabilities to Java EE applications by associating the Concurrency Utilities API with the Work Manager to make threads container-managed. You configure concurrent managed objects (CMOs) and then make them available for use by application components. Similar to Work Managers, CMOs can be defined at the domain level, application level, and module level, by using the Administration Console, MBeans, or deployment descriptors:
For more information about configuring and managing concurrent resources, see "Configuring Concurrent Resources" in Administering Server Environments for Oracle WebLogic Server.
Oracle provides a Default Data Source required by a Java EE 7-compliant runtime. This pre-configured data source can be used by an application to access the Derby Database that can be installed with WebLogic Server. See "Using the Default Data Source" in Administering JDBC Data Sources for Oracle WebLogic Server.
Simplified API defined by the Java Message Service (JMS) 2.0 specification. For more information, see "Understanding the Simplified API Programming Model" in Developing JMS Applications for Oracle WebLogic Server.
Oracle WebLogic Server 12.2.1 supports the Java EE Connector Architecture (JCA) 1.7 specification. For more information, see "Understanding Resource Adapters" in Developing Resource Adapters for Oracle WebLogic Server.
WebLogic Server 12.2.1 supports the Enterprise Java Beans (EJBs) 3.2 specification (JSR 352). For more information, see "Understanding Enterprise JavaBeans" in Developing Enterprise JavaBeans for Oracle WebLogic Server.
WebLogic Server 12.2.1 adds support for clustering and high availability with WebSocket applications. WebSocket clustering uses Coherence as part of its implementation to establish communication among all cluster members. WebSocket clustering enables horizontal scaling, allows you to send messages to all members of the cluster, increases the maximum number of connected clients, and decreases broadcast execution time.
WebLogic Server 12.2.1 adds support for GZIP compression in the WebLogic Web container, which you can enable at the domain or Web application level. With GZIP compression enabled, you can configure attributes, such as minimum content length and compression content types, and monitor related statistics. For more information, see "Enabling GZIP Compression for Web Applications" in Developing Web Applications, Servlets, and JSPs for Oracle WebLogic Server.
WebLogic Server 12.2.1 includes support for the following security standards:
Java Authorization Contract for Containers 1.5
Java Authentication Service Provider Interface for Containers 1.1 (JASPIC)
Packaged Permissions
Uncovered HTTP Methods (JSR 340 for Servlet 3.1
For more information, see Security.
The sample applications that can optionally be installed with WebLogic Server have been updated for Java EE 7, as described in the following sections:
Avitek Medical Records (or "MedRec") is a comprehensive educational sample application that demonstrates WebLogic Server and Java EE features, as well as best practices. In WebLogic Server 12.2.1, MedRec has been upgraded to demonstrate the following Java EE 7 features:
Java Persistence 2.1
Simplified API of JMS 2.0
Contexts and Dependency Injection 1.1
Batch 1.0
JAX-RS 2.0
JavaServer Faces 2.2
JSON Processing 1.0
HTML5
New sample applications have been added to show the following Java EE 7 features:
JSON Processing 1.0
Servlet 3.1
JavaServer Faces 2.2
Expression Language 3.0
Batch Processing
Concurrency Utilities
Contexts and Dependency Injection 1.1
Java EE Connector Architecture 1.7
Java Persistence 2.1
Java Message Service API 2.0
Enterprise JavaBeans 3.2
Java API for RESTful Web Services (JAX-RS) 2.0 asynchronous processing, filters and interceptors, and server-sent events (SSE) Jersey support.
WebLogic Server 12.2.1 supports the Enterprise Java Beans (EJBs) 3.2 specification (JSR 352). For more information, see "Understanding Enterprise JavaBeans" in Developing Enterprise JavaBeans for Oracle WebLogic Server.
Oracle WebLogic Server 12.2.1 is certified for use with JDK 8.0. Supported Oracle WebLogic Server 12.2.1 clients are certified for use with JDK 7.0 and JDK 8.0 Update 40. A certified JDK is required for running the WebLogic Server installation program. For more information, see the following:
The Oracle Fusion Middleware Supported System Configurations page on Oracle Technology Network.
"Roadmap for Verifying Your System Environment" in Installing and Configuring Oracle WebLogic Server and Coherence
Oracle WebLogic Server 12.2.1 is certified to run inside a Docker container. Docker is a Linux-based container technology that enables you to quickly create lightweight clustered and non-clustered WebLogic Server domain configurations on a single host OS or virtual machines, for either development or production environments.
As part of this certification, Oracle provides Docker files and supporting scripts for building images of Oracle WebLogic Server. These images are built as an extension of existing Oracle Linux images. These scripts and build images are available on GitHub at the following location:
https://github.com/oracle/docker/tree/master/OracleWebLogic
For more information, see "Getting Started" in Running Oracle WebLogic Server 12.2.1 on Docker.
Oracle WebLogic Server 12.2.1 builds on support from prior WebLogic Server versions to improve the reliability, availability, scalability and performance of WebLogic Server applications in clustered environments, when using new Oracle database features, in multi data center architectures, and on Exalogic Systems.
These support improvements are described in the following topics:
WebLogic Server 12.2.1 includes the following new and changed deployment features:
When a resource group references a resource group template, it inherits the application configuration defined in the resource group template. You can customize a specific application in a resource group by overriding the default application configuration in the resource group template.
To override the application configuration defined in a resource group template, specify a different deployment plan that the application should use for its configuration. You can apply application overrides or remove existing overrides using the Administration Console, Fusion Middleware Control, or by using the update or redeploy command with one of the supported deployment clients.
For more information, see "Overriding Application Configuration" in Deploying Applications to Oracle WebLogic Server and "Overriding Application Configuration" in Using WebLogic Server Multitenant.
WebLogic Server 12.2.1 adds support for parallel deployment. For use cases involving the deployment of multiple applications, the deployment of a single application with multiple modules, or the deployment of one or more applications across multiple partitions, parallel deployment improves startup and post-running deployment time. In multitenant environments, parallel deployment helps avoid cross-tenant performance impact.
For more information about parallel deployment, see "Enabling Parallel Deployment for Applications and Modules" in Deploying Applications to Oracle WebLogic Server and "Enabling Parallel Deployment in Multitenant Environments" in Using WebLogic Server Multitenant.
WebLogic Server 12.2.1 enhances FastSwap to work with the Java EE Contexts and Dependency Injection (CDI) specification.
Used in development mode, FastSwap helps developers avoid redeployment of an application and reduce turnaround time during development iterations. To improve the developer experience, you can now use FastSwap with CDI. For more information about FastSwap, see "Using FastSwap Deployment to Minimize Redeployment" in Deploying Applications to Oracle WebLogic Server.
Oracle WebLogic Server 12.2.1 adds several deployment performance enhancements. Improvements include:
Application class loading in parallel.
Indexing of class finder data to locate classes and resources faster.
Deployment factory caching during identification of a deployment, helping large deployments process faster.
Annotation scanning caching for libraries and applications, benefiting server restart and resulting in faster deployment time.
Annotation scanning in parallel so that each JAR file in the class path of a module is handled in parallel.
As of Oracle WebLogic Server 12.2.1, application names must be unique within each deployment scope. When deploying an application globally to a domain, if that application name is already in use in the current domain, the application deployment fails. This is a behavior change from previous WebLogic Server versions, when specifying the same application name caused WebLogic Server to automatically derive a unique name based on the specified name.
WebLogic Server 12.2.1 includes the following new and changed features:
In previous releases, adding a new JDBC driver or updating a JDBC driver where the replacement JAR has a different name than the original JAR required updating the WebLogic Server's classpath to include the location of the JDBC driver classes. In 12.2.1, you can simply put the drivers in the $DOMAIN_HOME/lib directory and not have to change the classpath. For more information, see "Adding Third-Party JDBC Drivers Not Installed with WebLogic Server" in Administering JDBC Data Sources for Oracle WebLogic Server.
Oracle provides a new data source type which provides the ability to switch between databases in a WebLogic Server Multitenant environment. For more information, see "Using Proxy Data Sources" in Administering JDBC Data Sources for Oracle WebLogic Server.
Data Source configuration and monitoring support for WebLogic Server Multitenant. For more information, see "Configuring JDBC" in Using WebLogic Server Multitenant.
Universal Connection Pool (UCP) data sources are now available as an option for users who wish to use UCP to connect to Oracle Databases. UCP provides an alternative connection pooling technology to WebLogic Server connection pooling. For more information, see "Using Universal Connection Pool Data Sources" in Administering JDBC Data Sources for Oracle WebLogic Server.
Connection leak profiling enhancements include:
A new attribute, Set Connection Leak Timeout Seconds, that can be used instead of Inactive Connection Timeout Seconds to specify the length of time before a reserved connection is considered leaked.
Two new profile records:
JDBC Object Closed Usage—Collect profile information about application components that close a connection, statement, or result set.
Local Transaction Connection Leak—Collect profile information about application components that leak a local transaction (start it but don't commit or rollback the transaction).
For more information, see "Collecting Profile Information" in Administering JDBC Data Sources for Oracle WebLogic Server.
You can set connection-based system properties using variables based on your environment. For more information, see "Enabling Connection-Based System Properties" in Administering JDBC Data Sources for Oracle WebLogic Server.
Application Continuity (or Replay) statistics are available using the JDBCReplayStatisticsRuntimeMBean for Generic and Active GridLink data sources. For more information, see "Viewing Runtime Statistics for Application Continuity" in Administering JDBC Data Sources for Oracle WebLogic Server.
You can now use a property node list to configure the ONS node list. The property node list, which can be used instead of a single node list, is a string composed of multiple records, with each record consisting of a key=value pair. For more information, see "ONS Client Configuration" in Administering JDBC Data Sources for Oracle WebLogic Server.
A system property weblogic.jdbc.attachNetworkTimeout is provided that, after an attach to the server, specifies a network timeout that forces a round-trip to the database (using an Oracle ping database operation). The timeout is then unset. For more information, see "Database Resident Connection Pooling" in Administering JDBC Data Sources for Oracle WebLogic Server.
The documentation that describes this feature has been enhanced to include details about using EBR with JDBC connections, and describes how to configure WebLogic data sources to use Editions. For more information, see "Using Edition-Based Redefinition" in Administering JDBC Data Sources for Oracle WebLogic Server.
Procedures and guidelines have been included for planning and managing database maintenance and downtimes for Multi Data Source and Active Gridlink data sources. For more information, see the following topics in Administering JDBC Data Sources for Oracle WebLogic Server:
To enable ONS and JDBC replay debugging, you must configure Java Util Logging. For more information, see the following topics in Administering JDBC Data Sources for Oracle WebLogic Server:
In previous releases, the PasswordEncrypted attribute was not supported in data source definitions. This restriction has been removed. For more information, see "Using an Encrypted Password in a DataSourceDefinition" in Developing JDBC Applications for Oracle WebLogic Server.
WebLogic Server 12.2.1 includes the following new and changed JTA features:
Oracle improves XA transaction performance by providing the option to eliminate the writing of XA transactions to the TLog. XA transaction resources (Determiners) are used during transaction recovery when a TLog is not present. See "XA Transactions without Transaction TLog Write" in Developing JTA Applications for Oracle WebLogic Server.
In WebLogic Server 12.2.1, JMS includes the following:
Support for the WebLogic Messaging Service in multitenant environments, including:
Core WebLogic Messaging components including Modules, JMS Resources, Path Service, Stores, and external helpers such as JMS Destination Availability Helper.
Integration solutions, including the Messaging Bridge, JMS pools, and Foreign JMS Servers.
Store-and-Forward (SAF) agents, including JMS SAF and WSRM JAX RPC.
AQ JMS using Foreign JMS Servers.
For more information, see "Configuring Messaging" in Using WebLogic Server Multitenant.
WebLogic Server 12.2.1 provides new configuration options that simplify messaging configurations, improve high availability, and remove limitations from previous releases. Support includes:
JMS cluster targeted JMS servers and persistent stores have new cluster targeting features. They eliminate the need to individually configure many JMS resource artifacts for every server in a cluster by targeting of the resource artifacts directly to the cluster.Additional features are available when Migratable Services, Distribution-Policy, and Migration-Policy are all configured.
Automatic Service Migration: Automatically restart a failed JMS instance on a different WebLogic Server instance.
Restart-In-Place: Automatically restart a failed JMS instance on its running WebLogic Server instance.
Unit-of-Order and Unit-of-Work
Singleton Destinations
Cluster Targeted SAF Agents, Bridges, and Path Services
Fail-back: Return an instance to its original host server when the host server restarts.
In previous releases, the JDBC Store's retry mechanism would make one reconnect attempt and throw a JDBCStoreException if it was not able to reconnect to the database. In WebLogic Server 12.2.1, Oracle allows you to configure multiple retry attempts over a specified time period. reconnectRetryPeriodMillis specifies the duration of the reconnect retry period in milliseconds. reconnectRetryIntervalMillis to specifies the interval between retry connection attempts during reconnectRetryPeriodMillis.
In WebLogic Server 12.2.1, you can monitor message statistics and runtime properties for WebSocket applications and endpoints. Endpoint-level monitoring collects information per individual endpoint, while application-level monitoring aggregates information from all endpoints deploying in the given application.
The following MBeans have been added or modified to support WebSocket monitoring:
WebAppComponentRuntimeMBean
WebsocketApplicationRuntimeMBean
WebsocketEndpointRuntimeMBean
WebsocketMessageStatisticsRuntimeMBean
WebsocketBaseRuntimeMBean
You can also use the Administration Console or Fusion Middleware Control to monitor WebSocket applications.
For more information, see "Monitoring WebSocket Applications" in Developing Applications for Oracle WebLogic Server.
WebLogic Server 12.2.1 integrates the policy classloader implementation as the default system class loader when using WebLogic start scripts. The policy classloader improves class loader performance and server startup time and is supported in all WebLogic modes (development and production).
WebLogic Server 12.2.1 integrates the ReadyApp framework. At times, applications are not fully initialized when WebLogic Server completed its startup process. By using the ReadyApp framework, applications can register with the WebLogic Server ReadyApp during the deployment process and influence the true 'ready' state of the server instance. Applications notify ReadyApp of their application state so server instances can determine if an application is fully initialized and ready to accept requests. ReadyApp also allows load balancers to detect server readiness by providing a reliable health-check URL.
Oracle WebLogic Server 12.2.1 provides the following new and changed features for RESTful web services:
Provides support for Jersey 2.x (JAX-RS 2.0 RI) by default in this release. Registration as a shared library with WebLogic Server is no longer required.
Provides enhanced monitoring of RESTful web services in the WebLogic Administration Console, including enhanced runtime statistics for your RESTful applications and resources, detailed deployment and configuration data, global execution statistics, and resource and resource method execution statistics. The following runtime MBeans have been modified or added to support enhanced monitoring:
JaxRsApplicationRuntimeBean
JaxRSExceptionMapperStatisticsRuntimeMbean
JaxRsExecutionStatisticsRuntimeMBean
JaxRsResourceMethodBaseRuntimeMBean
JaxRsResourceMethodRuntimeMBean
JaxRsResourceRuntimeMBean
JaxRsResponseStatisticsRuntimeMBean
JaxRsSubResourceLocatorRuntimeMBean
JaxRsUriRuntimeMBean
Includes the ability to disable RESTful web services monitoring at the individual application level, or globally at the domain level.
Reflects support for the Jersey 2.21.1 (JAX-RS 2.0 RI).
Supports securing Jersey 2.x (JAX-RS 2.0 RI) web services using Oracle Web Services Manager (OWSM) security policies.
Adds support for Java EE 7.
For more information, see Developing and Securing RESTful Web Services for Oracle WebLogic Server.
WebLogic Server 12.2.1 adds WLST commands to improve usability for dynamic cluster lifecycle operations. By using the WLST scaleUp and scaleDown commands, you can easily start and stop dynamic servers in a dynamic cluster and expand or shrink the size of a dynamic cluster.
For more information, see "Starting and Stopping Servers in Dynamic Clusters" and "Expanding or Reducing Dynamic Clusters" in Administering Clusters for Oracle WebLogic Server.
Oracle WebLogic Server 12.2.1 enhances TheadLocal clean out support in Work Managers. To clean up stray ThreadLocal use by applications and third-party libraries, configure the eagerThreadLocalCleanup attribute in the KernelMBean. By default, the self-tuning thread pool only cleans up ThreadLocal storage when a thread returns to a standby pool and after an application is undeployed. For more information, see "ThreadLocal Clean Out" in Administering Server Environments for Oracle WebLogic Server.
Oracle WebLogic Server 12.2.1 continues to provide new management features which simplify the configuration, monitoring and ongoing management of WebLogic Server domains and applications. These new features are described in the following sections:
WebLogic Server 12.2.1 introduces elasticity. Elasticity enables the automatic scaling of dynamic clusters and re-provisioning of associated resources based on demand. The Elasticity Framework leverages the WebLogic Diagnostic Framework (WLDF) policies and actions system.
For more information, see Configuring Elasticity in Dynamic Clusters for Oracle WebLogic Server.
WebLogic Server Multitenant introduces resource groups as a convenient way to group together Java EE applications and the resources they use into a distinct administrative unit within the domain. The resources and applications in a resource group are "fully qualified" in that the administrator provides all the information needed to start or connect to those resources, including credentials for connecting to a data source and targeting information for Java EE applications. A resource group will either contain these deployable resources directly or refer to a resource group template which contains the resources. Resource groups can be defined at the domain level, or be specific to a domain partition.
For more information, see "Configuring Resource Groups" in Using WebLogic Server Multitenant.
Resource group templates are a named, domain-level collection of deployable resources intended to be used as a pattern by (usually) multiple resource groups. Each resource group that refers to a given template will have its own runtime copies of the resources defined in the template. A resource group template is a convenient way to define and replicate resources for multiple tenants. Resource group templates make it very easy to deploy the same collection of applications and resources to multiple domain partitions.
Resource group templates are particularly useful in SaaS environments where WebLogic Server Multitenant activates the same applications and resources multiple times, once per domain partition. Some of the information about such resources is the same across all domain partitions, while some of it, such as JMS queues and database connections, varies from one partition to the next. WebLogic Server Multitenant provides several methods for overriding resource definitions:
Resource Override Configuration MBeans
Resource deployment plans
Partition-specific application deployment plans
Administrators can employ and combine any of these techniques.
For more information, see "Configuring Resource Group Templates" and "Configuring Resource Overrides" in Using WebLogic Server Multitenant.
Prior to this release, WebLogic Server supported only one active configuration edit session at a time. The system administrator got a global edit lock, made changes, and then activated them. Other administrators could not make changes at the same time. However, Oracle WebLogic Server 12.2.1 enables multiple, named concurrent edit sessions, which allows more than one administrator to make configuration changes at the same time. This is typically useful when multiple administrators work in different parts of the system. Also, when configuring a system takes a long time because of the serial execution of configuration commands, a single administrator can open multiple named edit sessions. This saves time by running the configuration edit sessions in parallel.
In a multitenant environment, more than one administrator will need to make configuration changes concurrently. A multitenant WebLogic domain contains multiple partitions each with its own administrator. Partition administrators must be able to make configuration changes to their partitions and the resources deployed in them without affecting other partition administrators or the WebLogic system administrator. Multiple, named concurrent edit sessions support one or more configuration edit sessions per partition plus global configuration edit sessions.
For more information, see "Managing Named Concurrent Edit Sessions" in Using WebLogic Server Multitenant.
RESTful Management Services are a publicly documented programming interface to Oracle WebLogic Server. In each release of WebLogic Server, the availability of REST resources for WebLogic Server administration has been enhanced and extended. In Oracle WebLogic Server 12.2.1, WebLogic RESTful management resources provide a comprehensive public interface for configuring, monitoring, deploying and administering WebLogic Server in all supported environments.
For information about the RESTful management resources provided in WebLogic Server 12.2.1, see Administering Oracle WebLogic Server with RESTful Management Services.
Fusion Middleware Control provides management support for all Fusion Middleware components, including WebLogic Server. Use Fusion Middleware Control to manage WebLogic Server when using other Fusion Middleware products in addition to WebLogic Server.
In WebLogic Server 12.2.1, the following subsets of functionality are now available in Fusion Middleware Control:
Create WebLogic Server clusters, server instances, domains, machines, and server templates
Configure applications and libraries
Create and configure UCP and proxy data sources
Create and configure JMS servers, Store-and-Forward agents, JMS modules, JMS resources, path services, messaging bridges, and messaging bridge destinations
Create and configure security realms
Manage WebLogic Server diagnostics
Configure elasticity for dynamic clusters
Manage WebLogic Server in a multitenant environment
For more information, see Administering Oracle WebLogic Server with Fusion Middleware Control.
The new security features provided in WebLogic Server 12.2.1 are described in the following sections:
WebLogic Server 12.2.1 supports the following Java EE 7 standards and features for security:
Java Authorization Contract for Containers 1.5 (JSR 115)
Java Authentication Service Provider Interface for Containers (JASPIC) 1.1 (JSR 196)
Packaged Permissions (Java EE 7 Platform Specification)
Uncovered HTTP methods for Servlet 3.1 (JSR 340)
The following enhancements have been added to the LDAP Authentication provider improve the configuration process:
LDAP Authentication provider performance enhancements for improved caching, searching, and LDAP server connection handling, such as:
The ability to collect hit/miss metrics on user and group caching, allowing you to determine the best settings for user and group caching to maximize response time and throughput.
Support for specifying a timeout on the LDAP server connection.
Support for testing the LDAP server connection prior activating the LDAP Authentication provider, similar to the way JDBC connections can be tested during data source configuration. Testing occurs automatically at the time you activate the this provider: if the test succeeds, the provider is activated.
For more information, see "Improving the Performance of WebLogic and LDAP Authentication Providers" in Administering Security for Oracle WebLogic Server 12c (12.2.1).
The default minimum version of the Transport Layer Security (TLS) protocol configured in WebLogic Server 12.2.1 is Version 1.1.
The WebLogic Identity Assertion and WebLogic Credential mapping providers have been enhanced to include support for the JSON web token, weblogic-jwt-token. This token type, which is configured by default in these security providers, is used internally for propagating identity among web applications in the domain.
In WebLogic Server 12.2.1, the WebLogic logging services include the following changes:
Partition scope logging — The logs for several WebLogic Server components, such as partition scope JMS, SAF, and servlet resources, are kept in partition-specific log files. The logs for server and domain scope resources, such as the server scope HTTP access log, the Harvester component, the Instrumentation component, and also the server and domain logs, can be tagged with partition-specific information to enable logging that is performed on behalf of a partition to be identified and made available to partition users.
For details, see "Monitoring and Debugging Partitions" in Using WebLogic Server Multitenant.
Note:
To revert the format of generated log messages to that they are compatible with the format used in versions of WebLogic Server prior to 12.2.1, you can enable theDomainMBean.LogFormatCompatibilityEnabled attribute. For information, see "Log File Format Compatibility with Previous WebLogic Server Versions" in Configuring Log Files and Filtering Log Messages for Oracle WebLogic Server.Monitoring for excessive logging — When enabled, the logging service monitors the domain for excessive rates of logging and, when present, suppresses messages that are being generated repeatedly.
For details, see "Preventing Excessive Logging" in Configuring Log Files and Filtering Log Messages for Oracle WebLogic Server.
In WebLogic Server 12.2.1, the WebLogic Diagnostic Framework (WLDF) includes the following changes:
The terms watch and notification are replaced by policy and action, respectively. However, the definition of these terms has not changed.
Four new action types are introduced as part of the Policy and Action component of WLDF. Actions are triggered when a policy expression evaluates to true. In addition to JMX notification actions, JMS message actions, SMTP (e-mail) actions, SNMP trap actions, and diagnostic image actions, WebLogic Server now supports the following new action types:
Elastic actions — scale a dynamic cluster up or down
REST notification — sends a notification to a REST endpoint
Script — executes an external command line script
Log — sends a custom message to the server log
In addition, WLDF enhances the SMTP action to allow you to send custom subject and body elements in an email message.
For more information, see "Configuring Actions" in Configuring and Using the Diagnostics Framework for Oracle WebLogic Server.
WebLogic Server 12.2.1 introduces dynamic debug patches. Dynamic debug patches allow you to capture diagnostic information using a patch that is activated and deactivated without requiring a server restart. Dynamic debug patching requires target WebLogic Server instances to be started with the WLDF instrumentation agent. For more information, see "Using Debug Patches" in Configuring and Using the Diagnostics Framework for Oracle WebLogic Server.
Oracle WebLogic Server 12.2.1 introduces smart rules. Smart rules are prepackaged policy expressions with a set of configurable parameters that allow the end user to create a complex policy expression just by specifying the values for these configurable parameters. For more information, see "Configuring Smart Rule Based Policies" in Configuring and Using the Diagnostics Framework for Oracle WebLogic Server.
When you initiate a diagnostic image capture, the images produced by the different server subsystems are captured and combined into a single .zip file. In previous releases of WebLogic Server, the components of a diagnostics image capture file all used the .img extension even though these files are all in text format and can be viewed in a text editor. In WebLogic Server 12.2.1, the file extensions have been updated to either .txt or .xml to clarify that these are text files.
For more information, see "Data Included in the Diagnostics Image Capture File" in Configuring and Using the Diagnostics Framework for Oracle WebLogic Server.
WLST command changes, described in WLST.
As of WebLogic Server 12.2.1, the WebLogic Server Development and Supplemental distributions are available as JAR files and are installed using the java command. The installation uses the Oracle Universal Installer (OUI) and is automatically done in silent mode; you only need to specify the ORACLE_HOME location for the installation.
WebLogic Zero Downtime Patching (ZDT Patching) automates the rollout of out-of-place patching or updates across a domain while allowing your applications to continue servicing requests. To use ZDT Patching, you create a workflow that orchestrates how updates are rolled out, and then you execute the workflow using use either WLST or the WebLogic Server Administration Console.
ZDT Patching supports the following workflow types:
| Workflow | Description |
|---|---|
| Move servers to a patched Oracle Home | Transitions the Administration Server or clusters, or both, to another Oracle Home that has already been patched using OPatch. |
| Update to a new Java version | Updates the Administration Server or clusters, or both, to use a newly installed Java Home. |
| Deploy updated applications | Deploys updated applications to the selected clusters. |
| Perform a rolling restart of servers | Sequentially and safely restarts the Administration Server or servers in the selected clusters, or both, including graceful shutdown and restart. |
For more information, see Administering Zero Downtime Patching Workflows.

Please note the following restrictions and advice when running Oracle WebLogic Server 12.2.1, and Oracle WebLogic Server 12.2.1 applications, on Java SE 8:
Oracle WebLogic Server 12.2.1 does not support applications using the new Java SE 8 fork/join and parallel streams features. Avoid these features when building Oracle WebLogic Server 12.2.1 applications using Java SE 8. The reason for this restriction is that the threads used by the fork/join thread pool will not be WebLogic Server managed threads. Any of the work performed in these threads may not be able to make use of WebLogic Server or Java EE facilities because the state of these threads, including security and transaction state, may not be created properly. Further, these threads will not be controlled by WebLogic Server Work Manager thread management facilities, possibly resulting in excessive thread usage.
Check all third party vendor software you are using for Java SE 8 compatibility. It may be necessary to upgrade to a later version of the software that correctly handles Java SE 8 classes, and some software may not yet be compatible. For example, the current version of the open source tool "jarjar" does not work correctly with Java SE 8 yet.
Java SE 8 has new APIs for JDBC 4.2 that are supported for versions of WebLogic Server 12.1.3 and later that are running on Java SE 8 with a JDBC driver that supports JDBC 4.2. However, although the Oracle JDBC thin driver bundled with WebLogic Server is certified on Java SE 8, the Oracle JDBC thin driver does not support JDBC 4.2. The Derby 10.10 driver that is shipped with Oracle WebLogic Server 12.2.1 has been tested with JDBC 4.2 and may be used. The corresponding Derby documentation is available at http://db.apache.org/derby/docs/10.10/ref/rrefjdbc4_2summary.html.
When running using SSL connections with JCE on JDK 8, it may be necessary to install the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 8. You can download the JCE Unlimited Strength Jurisdiction Policy Files for JDK 8 at http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html.
For the most current information on Oracle Fusion Middleware Licensing, see Licensing Information.
For the most current information on compatibility between current version of WebLogic Server and previous releases, see "WebLogic Server Compatibility" in Understanding Oracle WebLogic Server.
The certification matrices and My Oracle Support Certifications define the following terms to differentiate between types of database support:
Application Data Access refers to those applications that use the database for data access only and do not take advantage of WebLogic Server features that are Database dependant. WebLogic Server support of databases used for application data access only are less restrictive than for database dependent features.
WebLogic Server provides support for application data access to databases using JDBC drivers that meet the following requirements:
The driver must be thread safe.
The driver must implement standard JDBC transactional calls, such as setAutoCommit() and setTransactionIsolation(), when used in transactional aware environments.
Note the following restrictions:
JDBC drivers that do not implement serializable or remote interfaces cannot pass objects to an RMI client application.
Simultaneous use of automatic database connection failover and load balancing and global transactions (XA) with a highly-available (HA) DBMS architecture is supported with Oracle DB RAC only, and only for the Oracle DB RAC versions indicated on the System worksheet. These HA capabilities are only supported by Active GridLink for RAC and Multi Data Sources with RAC. These HA capabilities are not supported on other Oracle DB RAC versions or with other HA DBMS technologies on other non-Oracle DB products. Multi Data Sources are supported on other Oracle DB versions, and with non-Oracle DB technologies, but not with simultaneous use of automatic failover and load balancing and global transactions.
Application data access to databases meeting the restrictions articulated above is supported on other Oracle DB versions, in addition to those documented in the certification matrix.
WebLogic Type 4 JDBC drivers also support the following databases. For these databases, WebLogic Server supports application data access only, and does not support WebLogic Server database dependent features:
DB2 for z/OS 10.1
Informix 11.7+
When WebLogic Server features use a database for internal data storage, database support is more restrictive than for application data access. The following WebLogic Server features require internal data storage:
Container Managed Persistence (CMP)
Rowsets
JMS/JDBC Persistence and use of a WebLogic JDBC Store
JDBC Session Persistence
RDBMS Security Providers
Database Leasing (for singleton services and server migration)
JTA Logging Last Resource optimization
JDBC TLog
