- Actions
- Read the UDDI specs to relate to SD API - Steve F - 31/10/2005
- Code Registry and Schema - Alastair - 27/4/2006
Registry is just about there - but without replication of course. Uses a dummy schema. Using Martin's remote registry service which needed some changes. Not yet described in design. - Try to break JDK socket library - Alastair - 6/6/2006
Various ways to get socket into closed wait state. 1.4 and 5 look similar. It would appear that JVM being out of memory can provoke this. - Follow-up on MonAMI - Antony - 5/7/2006
Slight progress - Follow-up in Metadata Authz - Antony - 5/7/2006
- Package monitoring scripts - Antony - 7/8/2006
Generalized but not yet packaged. - Deploy monitoring scripts on PS,PPS and Preview - Antony - 7/8/2006
- Investigate protection against running out of memory -
Alastair -
7/8/2006
He thinks that we should detect and restart the service - not clear how to do it. Lots of discussion... Maybe we should make some measurements. Alastair has done some work (it stops the service, trys to start the GC and restarts the service). Tested with big linked list on 1.5 - it did not recover well. Maybe add another exception to allow service to say it is too busy. Maybe do a better job of estimating total memory used. - Follow up on gEclipse - Steve - 2/10/2006
- Consider extra functionality in SD to allow complex
queries on
ServiceData. - Paventhan - 2/10/2006
Discussion has started. He has also started looking at the code and the SAGA documents. - Try ETICS (cleanly) - Alastair - 2/10/2006
Done a bit and asked some questions. Alberto is converting an old 3.1 tag. - OGSA Naming into GLUE 2 - Antony - 2/10/2006
- Service Proxy Module - add to GIN etc - Alastair -
2/10/2006
Antony has done this for the job status raw archiver - can it be done in a more generic way? GIN has some bug fixes to make as well. Need to assign bug to Alastair - Antony will check that it is in Savannah. - Investigate Tomcat long running test (memory leak) and use of log4j - Alastair - 2/10/2006
- Find why the PPS SFTs are not working - Antony - 16/10/2006
- Contribute to devlopers' guide. It should be small and HTML compatible - lots of links. No repetition of other documents. No attempts to cover up inadequacies of other documents. - Alastair - 13/11/2006
- Circulate list of mail lists for people doing support - Alastair - 13/11/2006
- Update web page with instructions for how to carry out support - Antony - 13/11/2006
- Track down what has gone wrong with GridView reports. - Alastair - 13/11/2006
- Consider jGAF or gJAF - Ming - 17/11/2006
- Study - mode/state in consumer maybe mode is a substate. We should try to eliminate modes that overlap with state information - Kush - 17/11/2006
- Study start() in Consumer. In what circumstances can mode not be ``STARTED'' but already be RUNNING. Worse still if the task starts too soon (before STARTED) it will just do nothing. - Kush - 17/11/2006
- Eliminate RemoteService and RemoteResourceService - Kush - 17/12/2006
- In the Consumer the maximum count of tuples to pop does not appear to have been coded. This needs checking.- Ming - 17/11/2006
- The consumer has code to remove things from the HashMap (m_replies) but does not appear to add them. This needs checking.- Ming - 17/11/2006
- removeProducer call in consumer. This call is not in the spec nor in the design! Currently for a directed query it just sends reply.abort() and unlinks the reply otherwise it makes an asynchronous call to the mediator to get update instructions which are then sent to modifyPlan which will in turn abort the reply and unlink them. This needs checking. - Alastair - 17/11/2006
- In the consumer wouldn't it be better to pass the TupleQueue reference to the ProducerReply - but would there be synch issues?. This needs checking. - Alastair - 17/11/2006
- Does the resource need a flag to show when ready? This flag may not be necessary - it needs some thought. If startup and shutdown are synchronous it would appear not to be needed. This needs checking.- Ming - 17/11/2006
- In the resource code the resource manager is a singleton so there is only one timer therefore calling cancel will cancel all timer tasks. This needs checking. - Alastair - 17/11/2006
