17:00 → 17:20 Protocol discussion

Exception protocol discussion. See the latest protocol version.
How to stream big BLOB-s?
What if there are multiple big BLOB-s in one AttributeList? - Alexander's account on the topics.

paper CoralServerProtocol.pdf

Large blob-s are not handled by Atlas, so it is not the use case for the moment. So, we ignore this issue now, and we keep it as a constraint on the CORAL messaging. Alexander is working on the attribute list encoding. Query and QueryDefinition is ready.

17:20 → 17:40 Developmment status

• The observations with the latest CoralServer suite (CORALSERVER_0_0_7)
• Query and TableDescription achievments
• dbProxy development status
• Exception handling experiences

According to Alexander, his CORAL server version was able to execute the basic tests, so the server versions after it were regressions. He will reproduce that version, and we analyze the results. The server uses some functionality from Boost 1.35 that is not compatible with Boost 1.35. This version is installed in the nightlies, so Andy will need to recompile the server using the nightlies. Path to the nightlies: /afs/cern.ch/sw/lcg/app/nightlies/dev {DAY}

17:40 → 17:55 Plans for the next week

Try to execute the CORAL and COOL basic tests.
