6. Backup strategy Oracle Backup: /db/backup 142 Gb available - d0onprd - rman ( every day, keep 3 days, 1 set = 21 Gb ) - export (every other day, keep 2 days, 6 Gb each ) - d0on - rman ( every day, keep 3 days, 1 set = 7 Gb ) Backup to tape: DLT8000 tape drive mounted in a automated tape library with a 26 tape capacity in two 13 tape cartridges, almost 2 weeks of unattended backup Tape pool – 200 tapes, 12 week (3 month) rotation - full backup : /db (every Friday, 2 tapes) (d0onprd) /usr (every Monday, 1 tape) (d0on) - incremental: every day - every 3 months week long backup is kept forever

7. Performance: d0onprd Use Statspack Viewer 8.1.7 to monitor performance, every two weeks plots are posted on the web ( Online Computing)

8. Performance: d0onprd (2)

9. Performance: d0onprd (3)

10. DB access software currently supported 1)From Python: Dcoracle and Dcoracle2 2)From C++ : d0om_oracle It’s OK if user is using d0om, but if not? For online people use mostly python, but sometime there is a need to access DB from C/C++ programs Should we consider to provide support to users from generic C++ based on OTL (Oracle Template Library) ? Or OCI library? MisWeb: add graphics capability (?)
