Resend: Indeed, the PL/SQL engine can be in Oracle forms or reports. I wish it offered something equivalent to dba_* and v$* views, an easy way to monitor its working mechanism. For now, I'll write a cron job (in addition to another one that creates a dummy report) to run strace on all report server processes. If the output has strings like ORA-4020 or deadlock, it emails me.
