1. Database Administrator Workshop @ RAL Proposed Workshop Goals Dirk Duellmann, CERN

2. Meeting with LHCC RefereesDirk Duellmann2 Pre-Production Starts Soon Official start end of this month –Will ramp up during next three month –Larger scale (insert volume, clients and sites) – Goal: define full service setup for October milestone –At workshop after summer

3. Meeting with LHCC RefereesDirk Duellmann3 Pre-Production Service Targets Comments during discussin with LHCC reviewers –Experiments should define targets for “service success” –Main problem: DB payload and not always defined yet Proposal to ramp up tests using existing load generators (eg David Front’s COOL suite) –ATLAS paper for online COOL use case exists Number of IOVs / sec, payload rate Need similar target definition for Tier 1 –Now: start to explore parameter space –How far can we get with the current system? –Input to experiment planning

4. Meeting with LHCC RefereesDirk Duellmann4 Today Collect complete list of open service questions –Document answers (and alternatives) Implementation reference - how are the sites implementing the service User guide - how do experiment use the service –List open questions And agree on required tasks to conclude on them Short presentations by topic –Mainly to raise questions (and propose answers) Keep a log of the discussion –Turn that into wiki documentation after the workshop

5. Meeting with LHCC RefereesDirk Duellmann5 Main Topics –Database and storage configuration –Monitoring Initial OEM setup Agent installation, OEM configuration Session auditing and resource consumption –Network configuration and security connectivity and emergency procedure –User Support Bug reports & integration in existing problem handling (eg GGUS)

6. Meeting with LHCC RefereesDirk Duellmann6 Points for later Backup and Recovery –Assume Oracle in archivelog mode –Experiment DB from CERN will be backed up at source –Data created at a Tier 1 (grid services & castor) ? Shared DBA Service –Need to prepare accounts and required previledges –But after more experience with typical operations –Until then: each site administers site resources
