A bit more time needed - 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
Only runs on insecure port. Discussion with Paul underway. - Follow-up in Metadata Authz - Ming - 5/7/2006
- 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. - 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
- 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
This is becoming urgent. - Track down what has gone wrong with GridView reports.
- Alastair
- 13/11/2006
Need to get a decent r-gma python library to them very soon - and talk to them. - 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
Some more progress. - 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
Kush thinks it is OK - Steve will take another look. - Eliminate RemoteService and RemoteResourceService -
Kush -

See diagram. In progress. - In the Consumer the maximum count of tuples to pop has
not been
coded. - Ming - 17/11/2006
It will not generate a warning. In progress. - 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
It appears to be OK - Ming will add the explanation. In progress. - 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
- Look into SAM to ensure it checks R-GMA properly. Should it publish to GOC Node? Maybe Dave K could publish. - Steve - 27/11/2006
- Check pop documentation - Steve - 27/11/2006
- See if it is feasible to share a TaskQueue betwen
servlets - Kush
- 27/11/2006
Continue the work for now, but if it looks hard it should be done later. - Consider load on registry in new design - consider stored procedures in RDBMS - ??? - 27/11/2006
- Update schema design in doc - Steve - 27/11/2006
- Update "Remote Call Subsystem" in design doc - Steve - 27/11/2006
- Produce some "position" slides for Copenhagen - Paventhan and Steve - 4/12/2006
- Monitoring scripts don't detect some registry problems
- Antony - 4/12/2006
- Resource need no flag to show when ready. This should be explicit in the design - Steve - 4/12/2006.
- Consider impact of using a single servlet for all R-GMA - Kush and Alastair - 4/12/2006
- Eliminate RGMACheckSumException and RGMAUnsupportedProtocolException - Kush - 7/12/06
- Read the UDDI specs to relate to SD API - Paventhan -
