ok the server specs are a quad 1.4ghz pentium 4, 4gb memory running win2k
advanced server.
What I did was erase the old log and database volumes, then do a dsmserv -k
format with the log and database volume specs.
It created the volumes and formatted the recovery log volumes rather
quickly.
After it format's the recovery log volumes it does a recovery log volume
mount.
This is what is taking so long.
I've been monitoring the IO and it seems to be doing something to the
database disk, perhaps formatting the database volumes too? I don't know.
I've done this before but never with a database this large.

Thanks,
Mark

3 hours? Wow!. What's are the hardware specs of your tsm server? What else
is going on, on that system (topas, if AIX, or top)?
I would probably consider running either a database audit or re-org, then
try mounting it again.
thanks!

      On more thing, are you starting the server up again in the foreground
or background?. If your initially trying to start it up in
the background, kill it and start it up in the foreground first then let it
do all of it's redo log record and undo passes, as well as log mount.
Then once it's up, and you get a tsm server prompt. Then halt the server
and restart it in the background for production operation
at that point. Just another thought.

Yesterday morning I had an incident and lost one of the drives I had about
half my database volumes defined on.
I'm in the process of reformatting the log and database volumes so I can do
a database restore.
The database is 100gb and my log size is 13gb.
It's been mounting the log volumes for over 3 hours now.
Does anyone have any experience with a database this large in as far as
approximately how long it will take to format and mount the database/log
volumes?


Thanks in advance,
Mark Remeta
