Home -> Community -> Mailing Lists -> Oracle-L -> RE: TSPITR and one table per tablespace
I agree that putting every table in its own Tspace is a pretty Dilbert
thing to do.
However, we run Peoplesoft and had I the disk spindles available, there are at least a dozen or so of the most heavily hit tables which I would cheerfully put individually on their own Tspace on their own spindle.
Sometimes when I see the disk activity on the RAID subsystem I think it might go into meltdown.
