Database services

  • Experiment reports:
    • All databases upgraded to Oracle 11gR2 ( Additional interventions to change the compatible parameter were necessary.
    • Latest Oracle security patches applied on all production databases.
    • Hw (storage) problems observed in RAC10. Several interventions already performed transparently. One issue this week due to high load also related to the storage problems. Being investigated by NetApp support.
    • CMS online database has been migrated today back to the CMS PIT.

  • Site reports:
Site Status, recent changes, incidents, ... Planned interventions
BNL Migration of Conditions database to 11gR2 ( and a new hardware. In addition, latest CPU Jan 2012 patch was applied Decommissioning former Condition DB 10gR2 database Wed 29.02
KIT Old hw being decommissioned Maintenance downtime in the week 12.03-16.03: migration of Compass-LFC Schema to the new Hardware (FTS-DB) and upgrade to 11g. The FTS-DB will be down on 14.03 approximately between 9:00 14:00 CET.
IN2P3 Waiting for patch to fix issue with Oracle installer (SR 3-5225032577, bug 13731278)  
PIC FTS database was upgraded last tuesday, and at the same time, LFC of ATLAS database was completely stopped due to LFC migration to CERN. Currently all databases are in There are no scheduled interventions.
RAL Applied the Jan PSU on the 3D system ( Compatible parameter has not been changed accordingly since the intervention was announced as an at risk. Castor DB will be moved to new HW next week on Tuesday
TRIUMF ntr  

  • Decommissioning of the 3D OEM.
