How to see DBMS_OUTPUT error when pl/sql proc runs in the EM job scheduler?

Question

I have a pl/sql package that uses DBMS_OUTPUT to handle exceptions. When I run the package in sql*plus:
set serveroutput on;
begin
mypkg.myproc;
end;
and there is an exception, I see the output from my DBMS_OUTPUT.PUT_LINE.
However, when I use the job scheduler in Enterprise Manager... if there is an error, I do not see the output from my exception handling code (i.e., the output from DBMS_OUTPUT.PUT_LINE).

Answer 1

Using DBMS_OUTPUT to handle exceptions is generally not considered good form. At a minimum, you would want to log the exception to a table (or a file). If you are catching an exception that you cannot handle, you would really want to let that propagate back up to the caller so that Oracle knows that the job failed and can take appropriate action (i.e. retrying, not running dependent jobs, notifying a DBA, etc).
