IMHO, you failed to mobilize enough resources within Oracle to assist you.

This phrase confuses me:

> terminated the available patches...

I believe the phrase
>"but recently we have terminated the available patches..." loses something in the translation.
Does that mean that you terminated your Oracle Support contract? If so, then you shot yourself in the foot. If you were not happy with Oracle Support's response on your issues, you were entitled to escalate the issues, provided that you were meeting their criteria for working with them.

If you are not willing or able to apply patchsets and patches, then you don't belong running the software. Period.

why do I have a very strong feeling that you did not have a test system, and all changes were being applied to the production database on the production system?

how far up the chain within Oracle and SuSE did your issues go? did you attempt to post issues on the oracle-linux-l list?

People have 9.2.0.4 RAC running on Linux in production. Its highly likely that most of the issues that they have encountered have been identified and addressed via patches.

Your lack of willingness to apply them (patches) makes me think that I have completely wasted my time in posting to this thread.

good luck in your search for a turnkey solution that requires no work on your part.
