APEX

We are currently running Application Express 4.02 using Oracle Web Logic on a Suse Linux 11 server. We had a new database set up for APEXPRD port 1542 that was working correctly with application express. We also had a database set up for APEXTST port 1542 (on a different database server). We removed the APEXPRD database from the database server using DBCA and then used OEM to clone the APEXTST instance to the production server. Our new database instance has the name APEXPRD with the port 1542. We have recycled all services on the APEX server but our APEX Production site no longer runs -- just getting unable to display page error 404. We checked our dads.conf file to ensure no changes were needed but everything appears correct there since the database name and port did not change.

Is there anything within the database or any other configuration files that I would need to change to get APEX to work after a database clone?

Thank you!
