dbms_output.putlin show up AFTER completion???

P: n/a
Hello all,

I have made a procedure which is running a very, very long time (about
20 hours)

Within the procedure I put some output-lines, to show the user that
the procedure is still running. Lines like this
DBMS_OUTPUT.PUT_LINE('percentage ready : '!!mypercentage);

But when I start the procedure I DO NOT see these lines. The lines do
appear AFTER the procedure is finished. So after 20 hours I get a lot
of output-lines at once.

How can I show the user the lines while running the procedure???

(Using oracle 8.1.7, I am starting the procedure from sql+ (exec
Thanks a lot and kind regards,

you just discovered (the hard way, unfortunately!) probably the
biggest drawback of PL/SQL! What you have to do is rely on something
else than DBMS_OUTPUT.PUT_LINE to find out where you are in your
subroutine. I personally usually make use of
DBMS_APPLICATION_INFO.SET_MODULE spread through the code to see where
my PL/SQL block is at. If using this, you need to look in V$SESSION
(columns ACTION and MODULE) to see where the program is. One more
spy on the dynamic view V$SESSION_LONGOPS to see where you're at). 20
hours seems like a very long time for a procedure. What about posting
your code so that we can give some ideas for performance improvement?
Or you can email me if you want.
