Hmm... I agree with Wanda and Dwight.  Definitely not in the Activity Log.
However, if there were an option you could turn on in the dsmserv.opt to
have all your proposed output directed to the server's stdout, you could
easily capture it with dsmulog or whatever else you might like to use.

Realistically, though, I can't think of too many situations where seeing the
output of other admins' queries and selects would help me very much, and
most things that aren't a queries or selects are pretty self explanatory.
Out of curiosity, what would you expect to get from it?
