Re: Database and log format question.

Hi
When referring to "mounting the logs", do you mean the recovery log mount
which is initiated during dsmserv startup?
The db volumes you lost, do you have fresh copies of theese? As I
understand it, you need to do a database restore, which for me means that
your databas is unusable. In this case, you should define the new volumes,
do a dsmserv format, and then do the restore. If you choose to do a commit
of the logs, then the answer is yes, this will take a very long time, as
TSM will need to commit everything that is stored in your log(13GB:s).
If you're running TSM on a UNIX box, easiest thing todo is to check your
IO stats to see wether or not the database disks are used. If you dont
have any activity, there's a large possibility that the dsmserv process
has hung.

Database and log format question.
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
