09:30 → 10:10 New Middleware Directory Server (M. Sobczak)

The prensentation will focus on the new middleware directory server that is planned to replace the existing solution. Improvements in reliability, scalability and convenience for final users as well as the potential for future growth in the area of application and middle-tier software will be presented and explained. In addition to the technical presentation, the transition plan for the middleware users will be announced.

10:10 → 10:40 Oracle Publishing in the Control System (K. Kostro)

The requirement for publishing modifications of important data stored in Oracle databases (e.g. accelerator modes) has existed since some time. The Oracle technology ‘Oracle Streams Advanced Queuing’ (AQ) that provides database-integrated message queuing functionality became available to us in March 2008 following an upgrade of all of the Accelerator databases. Mid 2008, a first implementation using AQ was developed and used operationally to publish certain LHC data via DIP to the experiments. Recently the publication implementation was improved, simplified, and a CMW server put in place – enabling subscriptions to database changes to be made in a generic manner. This facility is fully managed by the DM section, and will be used to publish key data changes from the accelerator databases.
