---++ Database services

   * Experiment reports:
      * Generic:
         * LHCb and ATLAS downstream capture databases have been patched to 10.2.0.5 on Wednesday 5th of Jan.
      * ALICE:
         * Online DB upgraded to 10.2.0.5 on 12 of Jan
         * Online DB not available between 19th of Jan 16h and 20th of Jan 19h due to power tests in the pit.
      * ATLAS:
         * Atlas offline database for ADC applications (PANDA, DQ2 and prodsys accounts) have been moved to a dedicated database on Monday 17th of Jan 2011. The operation has involved a scheduled downtime for the affected accounts from 9am till 6pm and has included a full backup to tape of the new DB accounts. The rest of Atlas offline DB, in particular conditions and PVSS have been untouched.
         * Atlas online DB has been upgraded to 10.2.0.5 on Wednesday afternoon (19th of Jan).
         * After the CC power cut on 18th of December, the ATLARC database did not want to reboot. The investigation showed, that one of online log files was corrupted. This file has been already archived by the database but it turned out that it was archived corrupted. That looks like a database bug, since a corrupted online log file should not be archived successfully. In the consequence, the restore of the database from the backup was needed. The recovery operation was possible only to the point in time few hours before the power cut (7.30 a.m.), because TSM service lost some backup data after power cut and the existing archivelog was corrupted. The users agreed to restore the DB to the point in time several hours before, without waiting for TSM to be able to recover more data. 
      * CMS:
         * CMS online DB was not available between 8:25 and 19:10 on the 4th of January, due to power cut in P5. Manual interventions were require to start the DB after power was back (~17h).
         * Maintenance activities over the weekend on schemas replicated by CMS PVSS streaming introduced aborts and high latency of the replication. To avoid further problems other changes has been done manually on the target database - 17th of Jan
         * CMS online production database was stopped twice during last week on Monday and Tuesday morning (10-11 Jan). First downtime was necessary due to power tests at P5. At the same time several disks critical for database operation were replaced with new ones. Second downtime was related to upgrade to 10.2.0.5. The upgrade was completed successfully. 
         * CMS offline database has been upgraded to version 10.2.0.5 on Wednesday afternoon (19th of Jan).
      * LHCb:
         * LHCb online DB was not available between 0:10 and 19h on the 20th of Dec due to scheduled power tests in LHCb pit.

   * Site reports:
| *Site* | *Status, recent changes, incidents, ...* | *Planned interventions* |
| ASGC | LFC DB upgraded to 10.2.0.5 | None |
| BNL | Conditions DB - underlying storage firmware patches applied%BR%Updates of OS RHEL 5 and Oracle to 10.2.0.5:%BR%- LFC BNL, LFC Tier 3 and FTS database service successfully migrated to a new hardware (head nodes/storage)%BR%- VOMS / Dcache Priority Stager database successfully migrated to a new hardware service (head nodes/storage) | Upgrade 10.2.0.5 Conditions DB |
| CNAF | | Still no exact plan for the 10.2.0.5 upgrade, but will define it soon.  |
| KIT | A new DBA: Stefan Waldecker | Upgrade of 3D RACs (ATLAS, LHCb) to Oracle 10.2.0.5 on Jan 26 (during full GridKa/DE-KIT downtime 7:00-18:00 UTC). |
| IN2P3 | Nothing to report | - DBLHCB,DBATL and DBAMI - On 8th feb [9:00 - 18:00 CET], we are going to upgrade our storage system and network switch. All 3D databases will be shutdown during this intervention. %BR%- DBAMI - On 20th Jan, we will add a new schema into the AMI stream. |
| NDGF | Nothing to report | None |
| PIC | | We are planning a downtime for early of February to upgrade our Oracle databases and other tasks, but the date is not fixed yet. |
| RAL | We have installed the new CASTOR and ATLAS LFC hardware which is now been tested. Next step is to install Data Guard in High Availability mode and test it before going in production. | - Planning to upgrade Castor DBs on the 31st if we get the final approval from the experiment.%BR%- Waiting for CERN to finish their upgrade before we proceed to upgrade our 3D and LFC/FTS DBs |
| SARA | Successfully moved the database back to the original cluster hardware on 18th of Jan | No date for 10.2.0.5 upgrade yet |
| TRIUMF | Nothing to report | Planning to upgrade to Oracle 10.2.5 sometime in February. |
