Operations News

  • Tape servers upgraded to 2.1.10-0
  • On Thursday DB team changed an OS parameter on all remaining nodes to fix internal logging at ORACLE's request. It will only be known whether this change is successful at the next intervention.
  • No increased rate of failures on 4 WNs upgraded to CASTOR Client 2.1.10-1

Operations Problems

  • On Wednesday, continuing high load from CMS caused instability on LSF which led to 1h30m of unscheduled downtime. Restarting LSF didn't help, when large logs were re-created upon startup. It only started after all LSF logs were deleted. The logging level has now been reduced on this instance.

Blocking Issues

  • Lack of production-class hardware running ORACLE 10g needs to be resolved prior to CASTOR for Facilities can guarantee the same level of service as the Tier1 instances. Has arrived and we are awaiting installation.
