- 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. - Deploy monitoring scripts on PS,PPS and Preview -
Antony -
7/8/2006
Monitor what can be monitored on both PPS and Preview. - 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. - 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
Made contact with Torsten. - 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. Rgma17 is now going quite well. - Eliminate RemoteService and RemoteResourceService -
Kush -
17/12/2006
Good progress - but a bit more work needed with "ping". - 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 - Alastair - 27/11/2006
- Update "Remote Call Subsystem" in design doc - Steve - 27/11/2006
- 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 (spec) - 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 remain as an internal call. - ??? -
11/1/2006
Need to remind ourselves about the spec - Alastair, Antony and Steve - 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
Will use an inner class for each service to be contacted. - Problem with registry needing repair tables. Should investigate relative timings of check table and repair - and find a fix - Antony - 11/12/2006
- Describe measuremntdate and time format in doc - Steve - 11/12/2006
- Make CLI updates available with 20 minute termination interval - with test - Kush - 18/12/2006
- Look into new job wrapper scripts - Antony - 18/12/2006
- Cable up rest of machines - and turn off what is not needed on Friday morning - Alastair - 18/12/2006
- Need an RGMABusy exception (code) - Kush - 18/12/2006
- Produce a list of messages which we need to deal with for compatibility (such as StreamingProperties and QueryType) - Alastair - 18/12/2006
- Make the quick start web page point to the user guide. Should ask Stephen B. User guides need to point to new web pages and some refs to non existent env setup script at CERN need removing - Antony - 18/12/2006
