There is too little information to do any more than speculate (guess).

When troubleshooting problems, you need to consider the system as a whole,
and not focus only on the area where the problem was immediately evident
(in this case, dsmsched.log). For TSM, you need to consider, at a minimum,
the TSM server (where the schedule is defined), the TSM client scheduler
(which writes dsmsched.log) , the TSM client acceptor (CAD) which you are
using to manage the scheduler, and the environment as a whole (client
machine, server machine, network, and any other related patterns that
might provide insight).

So with that in mind, your investigations should include examination of:

- The TSM server activity log for the duration of the schedule window
(from 17:43 through whatever the duration of the schedule is).
- The TSM server schedule definition and associations, to ensure that the
schedule definition or associations have not changed unexpectedly.
- The TSM client acceptor log file (dsmwebcl.log).
- The TSM client error logs (dsmerror.log, dsierror.log)
- The TSM client schedule log (dsmsched.log, which you've already examined
somewhat)
- The TSM client options file to verify that the options are configured
correctly for your environment

Also check the following:

Prevalence of the problem. For example, determine whether this happens
every day, or just one time. Check whether any other clients are affected,
or if only this one client is affected.

Check whether there are any networking issues (network itself, firewall,
etc.) that might have contributed to the schedule being missed

Check whether the CAD was stopped, or the machine powered down at the time
the schedule was to run.

Check the schedule duration. Very short duration (for example, 5 minutes
or less) might not run. Make sure the schedule has a reasonable duration.
I recommend at least 1 hour.

Check whether the TSM server was running and available to clients at the
time the backup was supposed to run.

There are almost certainly other things to investigate, too, but this
should help you get started.

Andy

Fairly basic stuff here - the TSM scheduler must be running within the
schedule window if you want TSM to do something.

This line in the schedule log:
08/22/06   14:39:53 Scheduler has been stopped.

And this line after it:
08/22/06   22:39:55 Scheduler has been started by Dsmcad.

Indicate that the scheduler was not up when the TSM server tried to
contact it - I guess you have it as a MISSED schedule?

Quote "Either the window has elapsed or the schedule has been deleted
:-S which is not true"

TSM is correct in reporting that the window had elapsed.

We have shadow scripts here to ensure that if the scheduler falls over,
the script picks it up again. It may be worth your while implementing
something like this if you want to make sure you don't miss the
scheduled window for backup.

Not to appear rude, but, this is simple stuff - please either go an a
course or read the manual(s).

Regards,
Matthew

why didn't scheduler start at 17:43 on 22.8 (yesterday) ????
the message in error log says :

Either the window has elapsed or the schedule has been deleted

:-S which is not true

i'm confused. i asked for help month ago and nothing :-)
