  • <big> EGEE issues coming from ROC reports </big>
    Reports were not received from these ROCs:
    1. (CERN ROC): Maintenace day correctly handled by GOC, but timezones in SAM were all wrong. They had the maintenance starting 8 hours earlier than it did, i.e. interpretted GOC time as UTC rather than PST. This lead to SAM reporting filure diring downtime, and affects efficiency stats. https://gusiwr.fzk.de/pages/ticket_details.php?ticket=12884.


    2. (CERN ROC): SAM test in every job on WN seem to take up to 300s at beginning and end of job - this is an enormaous waste of cpu, and makes job turnaround poor. Can we disable it? Do other sites see this, or could it be a local mon box(rgma) problem?


    3. (France ROC): How is a VOMS proxy mapped on a grid node (CE, SE, etc.) using LCMAPS ? Is there an official document that explains this mapping mechanism?


    4. (DECH ROC): 64-bit support: Do others have experience finding workarounds? (in addition to discussion e.g. on LCG Rollout, "Who's planning to move to SL/SLC/CentOS 4.x and when?")


    5. (DECH ROC): Problems with LFC upgrade - Impression: testing/certification of MySQL related middleware features has flaws. Improve MySQL support for the future? Is the current testing of MySQL in PPS enough?


    6. (SE Europe ROC): It seems that CIC daily reports for sites contain incorrect links to SAM failures details as of today: https://gus.fzk.de/pages/ticket_details.php?ticket=20043


    7. (SE Europe ROC): One site in IL reports that they get "submitter proxy expired" ggus ticket https://gus.fzk.de/pages/ticket_details.php?ticket=19854 any ideas?


    8. (UK/I ROC): The site is marked as having failed some replica management tests on 22-03-2007. However, the "details" link does not display any data about this job or the reasons for this job failure.
