Thanks for your response. I have added the oracle account to the groups you mentioned and I still get the same error. I am looking into the vendors info on SHMAT at the moment.

I have been away from Oracle for a couple of years, there used to be a site that was run by oracle and it was basically linked to their tech support database. I used to go there and enter the error number and it would bring up multiple entries of people with the same problem and OTS's directions on fixing the problem. Anyone know that site? Could you please tell me what site it is? Thank you.
