  • General announcements:
    • Licence agreement letters sent out, some already back and signed. Waiting for payments.
    • 3D quartely report done: changes on the milestones concerning phase 2 sites.
    • Data corruption Oracle bug: patch has been delivered. It would be nice if the sites can obtain the patch available in metalink and disable the workaround suggested. An email will be sent.

  • Update on phase 2 site status:
    • Triumf (Denise): hw and power installed but hw problem on the disk array.
    • PIC (Gonzalo by email): position for dba has been opened, still not completed the set of hw. Schedule: January 2007 available, March 2007 production.

  • LHCb and ATLAS COOL/TAGS tests:
    • ATLAS TAGS (Florbela): throughput tests only to GridKA. Networking tests to BNL ongoing: normal network latency impacting Streams throughput. Luca has run some tests on data transfer without using Streams, some improvement has achieved. Looking on how to tune Streams.
    • ATLAS COOL (Gancho): wait events on the apply site observed. Apply paralellism increased to 8 and streams_pool_size increased to 800M do not help the throughput.
    • LHCb (Marco): Online server upgraded to 10.2.0.2. Patches related to Streams bug applied. Waiting for the agents from the grid sw. Dirk proposed a base and continuous activity for the Streams environment to test the stability.

  • CMS Frontier tests:
    • Error using Persistency version 1.5.3: segmentation fault, few percentage of jobs being affected, crash happens on random status of the jobs. Using version 1.5.1 the error is not observed.
    • Cache refresh issue: plan for another meeting in order to know the CMS policy.
    • Authentication file uses Oracle pwd inside. Question: option to use grid certificates.
