Do you have archive logging turned on?

Yes: Is your log_archive_dest full?
Is the directory for your online redo logs full?

Last Friday, our 9012 database froze, I mean the only way we could get in was through sqlplus, no other tool would connect. We needed to bring the other side up as soon as possible so didn't spend any time running any queries to see what was the problem. The other side (of the cluster) wouldn't come up because it reported that some resource it needed was locked. So we had to shot the pmon process.

When analyzing the situation later, we found that Oracle didn't dump a single useful trace file, so contacting OWS was pretty much useless. OS logs were clean, no alarms raised there.

Has anyone encountered this situation that Oracle freezes and crashes without any trace files? How does one collect useful information in such cases? Are there any tools that we could use to gather at-lease some information before the DB crashes?

Thanks in advance for any ideas and tips. Raj
