- 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. It must also be protected from bad ACL files. - 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
Waiting for a reply - 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. Will add an RGMABusy 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. Will get the archiver going again - 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 -
17/12/2006
Good progress - but a bit more work needed with "ping". - 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
- 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
- Consider load on registry in new design - consider stored procedures in RDBMS - ??? - 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.
- It is possible to access our services on port 8080 if the server.xml has connector. We should be able to secure the service however the connectore is setup (as others may be using tomcat - Antony - 11/12/2006
- Need an RGMABusy exception - Steve - 11/12/2006
- Remove FIXME about "mode/state in consumer maybe mode is a substate." from design doc. - Steve - 11/12/2006
- Remove the "removeProducer" call from the consumer interface - or make it do nothing. It may reamin as an internal call. - ??? - 11/1/2006
- In the consumer, pass the TupleQueue reference to the ProducerReply - take care with synch issues. - ??? - 11/12/2006
- Refactor to use a single servlet for all R-GMA - Kush - 11/12/2006
- Problem with registry needing repair tables. Should investigate relative timings of check table and repair - and find a fix - Antony - 11/12/06
