Hi
We are using Informix 7.24.UC3 with Tivoli storage Manager on AIX 4.3.3. My
problem is about Database restoration.
I take complete databse backup by using onbar -b -w -L 0 command. For 194 GB
Database, system takes 3 hours and 30 min. But when I tried to restore same
backup using onbar -r -w -p, it takes around 26 Hours.
The hardware setup is as follows:-
RS/6000 H70 with 1.5 GB main memory, 2 SSA Advanced RAID controller
connected to SSA cabinet having 16 disks each of 36 GB. The 2 SSA
controllers have 4 SSA loops with 4 disks per loop and each loop is
configured as RAID 0.
The tape drive 3590 E11 is exclusively connected Fast / Wide SCSI controller
on H70.
The relevant contents of onconfig file are as follows:-
BAR_MAX_BACKUP 6
BAR_RETRY 1
BAR_NB_XPORT_COUNT 10
BAR_XFER_BUF_SIZE 4
BAR_BSALIB_PATH=/usr/tivoli/tsm/client/informix/bin/bsashr10.o
Can anyone have any helpful OS/Informix/Hardware level hints to reduce the
restoration time ?
Pls feel free to contact me in case of any doubt.
