2 Plan : –HDB size –TDB size –Infrastucture & security strategy May 26, 2010TANGO MEETING

3 HDB size 8835 attributs are in archiving 250 inserts per second PeriodQuantity > 1 hour minutes minutes minutes minutes452 8 minutes1 6 minutes1 5 minutes12 3 minutes50 1 minute secondes secondes1712 May 26, 2010TANGO MEETING

4 evolution May 26, 2010TANGO MEETING Grows 40G per month

5 HDB size Database size 1.1 To (1.7 To used) May 26, 2010TANGO MEETING

6 TDB size 6512 attributs are in archiving Should have 6400 inserts per second, but we use temporary files. PeriodQuantity > 1 hour minutes minutes545 1 minute secondes1 10 secondes317 5 secondes5 4 secondes197 2 secondes645 1 seconde ms ms10 May 26, 2010TANGO MEETING

7 TDB size TDB database : –Grows 21G per day –31 days kept online – files inserted per day (~3 sec for a file containing rows). May 26, 2010TANGO MEETING

10 Disk Array New storage configuration : –SAN (Fiber Channel 400Go disks) HDB : 3 To RAID5 (11 disks) TDB : 1,5 To RAID10 (10 disks) TEST : 1 To RAID4 (5 disks) –NAS (SATA 1To disks) BACKUP : 3 To RAID6 (~ 8 disks) –NAS (Fiber Channel 400Go disks) TDB_files : 1 To RAID5 (~ 6 disks) May 26, 2010TANGO MEETING

12 HDB Backup strategy Logical Backup : –Every 4 hours : synchronisation between HDB and degrad databases (configuration tables) –Every day : Export (Dumpfile) of configuration tables (ADT,APT,AMT) Physical Backup : –RMAN (Recovery Manager) Every day, Bkp RW, 15 Go (40 minutes) every 2 months, Bkp full, 300 Go (5 hours) –Copy Backup Ponctually, copy the backup to another media (band) –Test backup Ponctually, I restore the backup on test server. (3/4 times per year) May 26, 2010TANGO MEETING
