  6. D0 Taking Stock ’08 – Backup Space Used

  7. D0 Taking Stock ’08 – Backups Details • D0ofprd1 • Daily, 4 days of archives. • Allocated 4TB, Used 1.5TB (2 copies),Back-up time -> 2.25 Hrs. No Export. Both copies of rman backup to SAN. No local copy. • Backups to dcache 3x/week • D0lump • Daily, 4 days of archives • Allocated 3.5TB, Used 2.9TB (2 copies),Back-up time -> 6 Hrs. No Export. Both copies of rman to SAN.

  8. D0 Taking Stock ’08 - Accomplishments • Replaced the Clariion Array with 3par SAN storage including int/prd d0 offline database instances to 3par array. • D0 Online Production 317 minutes down 99+% uptime D0 Offline Production 525 minutes down 99+% uptime D0 Offline Luminosity Production 100% uptime • Took Over support for d0 online databases. • Upgraded the Oracle databases to version 10.2.0.3 • Deployed the Speaker Bureau schema to production. • OS and DB Security Patches up-to-date • Proof of product for ASO ( Advanced Security Option) • Deployed Six SAM Schama cuts • Reverse Engineering of Enstore Schema and deployed the supporting db tablespaces, users and roles.

  9. D0 Taking Stock ’08 - Next • Upgrade the Oracle databases to version 10.2.0.4 OR 11g • ASO ( Advanced Security Option) Deployment • Test Automated Failover of D0 online DB machines otherwise move to SAN • Rebuild of Indices for d0 luminosity. • Attach 3PAR array in order to have Integration refreshed from Production.

  10. D0 Taking Stock ’08 - Concerns • Single point of failure with D0 offline database. • Hardware for D0 DB server machines is very old. Should consider upgrading the hardware for d0 db servers. • D0 Online DB machines failover is manual. Working on to test the automation of script. If we continue with issue we need to revisit move back to the SAN.
