Michael,

There is not much to go on here... but since the
"TDPEXCC QUERY TSM" command uses the TSM API, it appears
as if there may be a possible problem with the TSM API
installation or pathing. Take a look at the DSIERROR.LOG file.
If it does not give you any ideas on what is wrong, your best bet
is to call IBM Support so some traces can be looked at to
find out exactly where the problem is occuring.

Thanks,

Del
