My db/system config: I have 256Mb of mem, and 2 x 166Mhz proc (F40).
The adsm database is on 6 db vols on 2 different disks. The dbvols are
mirrored by adsm, so I actually have 3 dbvols.
Maybe i should mirror the dbvols by AIX instead of by ADSM, I suppose that
it would give me better readperformance.
