Upgrade status and plans
• Upgrade to 10.2.0.5 • DLF and PPS databases already upgraded• SRM and Stager databases to be upgraded
when Heavy Ions run is finished (December)• Nameserver database to be upgraded during
January technical stop• Standard optimizer & statistics gathering to
be stress-tested to review the possibility of removing hints

New hardware plans
• SRM, Stager and DLF databases are to be migrated and consolidated
• Where: Gen3 machines: 48GBs RAM
Intel Xeon 8 * 2.27 GHz• When: January/February • Possible consolidation plans
• By experiment – 3 node cluster containing STAGER, SRM and DLF
• By DB type – separate clusters for SRM/Stagers and DLFs
