We have been dealing with IBM and Cybernetics for a few months trying to get
the write combination of drivers built to run Oracle RAC. Supposedly
everything is fixed, but now my database (just rebuilt) keeps getting
corrupt blocks. I don't expect an answer as to our problem, but what is
going to be the quickest way to determine the cause of the block corruption?
What trace mechanisms should I be activating from Oracle perspective? Block
checking and block check sum I assume, any specific RAC trace tools?
