FTS news
- FTS 2.2.8 now installed on the CERN pilot service. Stress tests from Altas, Phedex transfers, and Oracle 11 db all working. Action: Oliver will provide a table of FTS version / Oracle version / OS version compatibility. Now gLite FTS 2.2.8 is installed by CERN/IT/PES in production at the Tier0, wherelse EMI FTS 2.2.8 is installed on the pilot service (and in production at RAL). Official EMI release date is 2012/02/16. Sites should report every Thursday at the end of the daily meeting when they plan to upgrade so that all is done before LHC data taking (mid-March).
- gfal2, one of the component libraries for FTS3, has been released for beta testing - https://svnweb.cern.ch/trac/lcgutil/wiki/gfal2
- srmBringOnline being implemented at LHCb's request

Database services
- Experiment reports:
- All experiment databases have been successfully upgraded to 11gR2.
- January security patches have also been deployed all all experiment databases.
- Change of the compatible parameter from 10.2.0.5 to 11.2.0.3 ongoing.
- Several issues affected Streams replication after the upgrades:
- Bug when using segment advisor (metalink Streams Capture Aborting With ORA-26767 Due To Temp Tables Created By DBMS_COMPRESSION [ID 1082323.1]). Workaround: add additional capture rules to ignore offending LCRs.
- 11.2.0.3 cannot capture changes on compressed tables when 'compatible' parameter is not raised to 11.2.0.3.
- Compatible parameter has to be modified before or after the upgrade when all instances are up. Otherwise logminer will abort with ora-600. Making dictionary dump after change the parameter is a good practice.
- Capture process tends to crash during reading of logs written during upgrade. Workaround: recreation of the process to start just after the upgrade.
- Site reports:
| Site | Status, recent changes, incidents, ... | Planned interventions |
|---|---|---|
| BNL | None | Migration of the Conditions Database to 11g and a new hardware, Feb 22 2012. Oracle data guard (physical standby database) will be used during this intervention. |
| CNAF | LHCb updated to 11g on 31Jan-01Feb | We still have this problem of huge amount of FTS old data to delete, which is mainly slowing down FtsMonitor, that is too big to be purged by the official scripts. This issue will be treated starting with a clean DB after the scheduled down for FTS HW consolidation and upgrade to SL5+EMI. We are coming closer to this, but there isn't a fixed date yet. |
| KIT | Jan 24: ATLAS 3D DB migration to 11g, Feb 1: LHCb 3D/LFC DB upgrade to 11g and migration to new hardware. | |
| IN2P3 | On 7 february, ASM gets stuck what had for consequence to abort the apply process.ASM had rised many access errors to some old raw devices which had been deleted at the OS level.The problem has been fixed by bouncing machines Oracle has provided a solution for the problem observed during last upgrade attempt. Unfortunately the solution stop working just before redoing upgrade of LHCB database (09.02) |
|
| PIC | LHCb database upgraded to 11g (30.01) | Upgrade of FTS and migration of the ATLAS LFC is intended to do between 27th to 29th of february, but the exact day is not fixed yet. |
| RAL | LHCb 3D upgraded to 11g (31.01) | January security patches to be applied, no date yet |
| SARA | LHCb 3D upgraded to 11g (01.02) - took until 02.02 | |
| TRIUMF | Oracle's JAN 2011 CPU Patch applied to our ATLAS 3D, FTS & TAG database servers. | Short outage to change the database_compatible parameter to 11.2.0.3 to be scheduled |
