To completely install the DBMS_PROFILER package, run:

$ORACLE_HOME/rdbms/admin/profload.sql - to install the package (run as SYS)
$ORACLE_HOME/rdbms/admin/proftab.sql - to create the appropriate tables for the package. You can either run this script in the schema of the user who is going to use DBMS_PROFILER or, as I do, run it as SYSTEM, then create the appropriate synonyms and grant the appropriate permissions to use the tables.

Looks like DBMS_PROFILER is not installed using catproc. I found loadprof.sql rdbms/admin which will install it. Any other way to install it? I did not find any scripts in rdbms/admin which call profload.sql.

DBMS_PROFILER is great, if you have PL/SQL Developer, it has a great interface to it.

Hi guys

Thanx everyone, I found what was going on. A special thank-you to Raj for pointing out the dbms_profiler, what a wonderful tool. Using that tool I discover that it was my select, and not the parsing or inserts, that were causing the problem. I created a bunch of indexes for all my dimension tables, and voilà... Down to 500 rows in 5 seconds. I love that list :-)

FYI: SGA is fine, hit ratio ok, on that side, server and DB are going well, it was really my coding or pl/sql the problem. Now I know I was not helping my code at all.

Thanks again to everyone who helped. Merci Steph, je te répond bientôt...

Daniel
