  1. Online Databases Status V.Sirotenko, 11/1/2002 • Oracle 8i Servers, release 8.1.7.3 • Platform: Compaq Tru64 UNIX V5.1 (Rev. 732) • Production DB d0onprd, on d0olc, 64 users, • 34Gb allocated, 15Gb used • 79Gb disk space available, RAID-1 • Development DB d0on, server on d0olb, 105 users, • 24Gb allocated, 4Gb used • 36Gb disk space available, RAID-1

  2. User Applications • Platforms: Linux,OSF1 Unix,Windows • d0onprd: • 1) Detectors calibration and download APIs with online • to offline transfer tools ( smt,cft,muon,cal ) • EPICS hardware database (HDB) toolkit • RUNS database APIs : runGrabber/runPusher • Monitoring daemon: dbMonitor • d0on: • Solenoid Hall probes DB API (solGrabber) • FPD pot position/alarms DB API • historyDB (hisDB) toolkit : slow EPICS archiver

  3. Major schemas and tablespace usage in d0onprd TABLESPACE USED MB FREE MB TOTAL PERCENT USED ------------------------------ ---------- ---------- ---------- ------------------------------------------------------------------------------- CAL_CALIB 3006 994 4000 75 CFT_CALIB 2942 1058 4000 74 HDB_01 196 304 500 39 MUON_CMSC_CALIB 6 194 200 3 MUON_FMSC_CALIB 12 188 200 6 MUON_MDT_CALIB 3 197 200 2 MUON_PDT_CALIB 8 192 200 4 RUNS 389 1611 2000 19 SMT_CALIB 6387 2612 9000 71

  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 • From Python: Dcoracle and Dcoracle2 • 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 (?)
