This is not quite true on the reduction side. In my database, I see the
following response to QUERY DB:
Available Assigned Maximum Maximum Page Total Used Pct Max.
Space Capacity Extension Reduction Size Usable Pages Util Pct
(MB) (MB) (MB) (MB) (bytes) Pages Util
--------- -------- --------- --------- ------- --------- --------- ----- -----
3,392 3,132 260 4 4,096 801,792 267,744 33.4 37.5
3,392 3,132 260 4 4,096 801,792 267,744 33.4 37.5
Clearly, many more MB are unused in the DB than I can reduce it. I conclude
that there must be many holes in the DB that prevent any further reduction.
However, I'd like to remove one (out of four) of the volumes from the DB,
since
I'm only using a third of the space in there. How can I do this? Will DELETE
DBVOLUME cause the DB to move records out of the volume-to-be-deleted, or will
it simply refuse to act?
Thanks,
Rich
