If you mean SQLTRACE, that can only be constrained by database and/or user, not object name. You would have to poll it every few seconds for that procedure name, and in any case the return values are not accessible. You could use "SET DEBUG TO filename WITH APPEND" within the procedure, but the resulting file would be huge and cumbersome to extract what you want. The best solution would be to create a history table into which you insert a row at the end of the procedure. That could include parameters, return values, CURRENT, USER, etc.
