Thanks for the reply.
You are saying exactly what I said/read and felt. We did go through IBM
and Notes support and they couldn't come up with anything tangible to
explain the hangs.
People were constantly complaining about the slow-downs/hangs. When we
tracked them for a while, we noticed they always occured during the
archlog dumps being performed, every 2-hours.
I think IBM was the one who suggested the MOUNTWAIT parm (the Domino
person handled this). I told them that none of the management classes go
straight to tape. *ALL* backups (logs, daily, weekly) go to disk, first,
and this parm shouldn't make any difference.
When we added the MOUNTWAIT=NO, the complaints stopped and our monitoring
showed no more seizures.
I too realize it doesn't make sense but it did make a noticible
difference.

Re: [ADSM-L] Domino TDP and MountWait parm
Hi Zoltan,
The /MOUNTWAIT=NO says that if the backups need
to be stored on offline media that would require a
tape mount, then don't proceed with the operation.
If what you say is correct... and all log backups are going
to disk and not tape, using the /MOUNTWAIT=NO parameter
should have absolutely no effect. I have a feeling that the
accident and experimentation are probably more of a
coincidence... but you never know.
I would recommend placing a call with the IBM Support Team
so they can help you can get this sorted out.
Thanks,
Del

Solaris 9 - TSM 5.3.0 client
Domino TDP - 5.3.0
We have been having lot of issues with Domino servers/processes
hanging/stalling when the TDP backups kick off, especially when doing
transaction log dumping. Everything would seize up while the
transaction
logs were dumped. We also have been noticing slowdowns caused by the
actual backups.
Through accident and experimentation, we discovered this can
minimize/stop
these hangups by adding the /MOUNTWAIT=NO parm to the DOMDSMC command.
This makes no sense since the book describes this as waiting for tape
resources when in fact, all backups to all Domino systems go directly
to
a 2TB disk LZ.
Can someone (Del ?) please explain this and what are the consequences of
using this parm and why do I seem to need it ?
