  • CERN:
    • 3D: Dirk, Zbigniew, Luis, Eva
    • LHCB: Marco
    • RAL: Gordon
    • ATLAS: Florbela, Gancho

  • Update on phase 2 site status:
    • Triumf: Hw received, working on power setup, RACs will be installed next week (expected). Denise has reviewed documentation available on wiki.

  • Recovery tests with Streams:
    • First tests and results presented on the 3D workshop.
    • Recovery on source database (when source has applied transactions which have not sent to the destinations) test ongoing: RMAN + ASM have renamed the archive log files restored from the backup, so capture process hangs because it cannot find the archive logs to mine. Working on how to reasign the restored logs to the capture process with the Oracle Suppor help.

  • LHCb and ATLAS COOL tests:
    • LHCb:
      • database configuration problems (single node, basic installation)
      • Stream configuration completed. Marco will start the tests.
    • ATLAS:
      • Network problems to BNL: network expert required
      • Propagation to GridKA is not working since last intervention on the database
      • Observed:
        • David client - only inserts workload ~ 800 LCRs/sec
        • Stefan client - mix workload ~ 200 LCRs/sec
        • Update/delete operations contain old values => update/delete LCR is bigger than insert LCR
        • Update statements are rewritten from source database to destination database
        • To follow up with Oracle
