Hi Derek,

It looks like you have been struggling with this problem for at least three weeks, so I suggest being a little less academic and a little more pragmatic.

I would suggest going to your manager (or straight to the DBA) and ask whomever to open an SR with oracle about "why your sessions are 'disappearing'". This is not "normal" behavior (assuming there is nothing they catch right off the bat in the config). I wouldn't worry (right now) about any ORA-7445, or ORA-3135, or redo logs, or huge cursors of 35 million rows, etc.

Just open the SR with that as a generic question and ask where they suggest you start troubleshooting. If you have a support contract, they are getting paid a bazillion bucks, so you may as well use it.
