Re: Squishing the unused space out of my ADSM database

Hi Trevor, Brian,
I would be a bit cautious on the expected outcome of a smaller database
when using the dump/load DB. There is a very strong possibility that
the database will end up bigger than you started with! I can't explain
this in full detail but it is to do with the way records are packed into
DB pages when the load occurs, and space is left in pages for later
expansion.
I think Trevor is right with the time factor ... it would take
significantly longer (and then you might have to do the restore DB as
well to get back to what you are now).
I think there is a need for a tool for optimising and reclaiming space
in the ADSM DB and IBM should be encouraged to produce such a tool.
Regards, Sheelagh
