Help a newbie trying to learn PL/SQL - No trace is showing up

Hi Folks:

I'm doing the examples on p.126/127 of the Oracle 8i Advanced PL/SQL programming book. I have 9i installed so I am not sure if this makes a difference. Mind you, I've only been doing this since Thursday of last week so I am VERY new to this and a moron.

I created a user and have issued the following thru SQLPLUS
--

ALTER SESSION SET EVENTS '10938 trace name context level 10';

ALTER PROCEDURE RaiseIt COMPILE DEBUG;

• Anonymous block which raises some exceptions. BEGIN CallRaise(1001); RaiseIt(-1); END; /
  --
  

Then I go to the udump directory and examine the trace file and do *not* receive the stack trace like the book says I should. Rather I see the following in the trace file... Am I missing some type of setting/option in order to see the same call-stack trace that the book says I should see??? I don't see any callstack trace in this trace file... Although, I can query the sys.plsql_trace_events and the sys.plsql_trace_runs table and see data in it. I just don't see it echoed to the following trace file.

thanks in advance, Theron
