Hello everyone, I get the following error at the end of 9i installation, when the different tools are being started. The tool in question is the Database Configuaration Assistant, which fails during the "Creating and starting Oracle instance". I get the message "ORA-27123: unable to attach to shared memory segment". The error messages book says the following about error 27123:

Cause: SHMAT() call failed.
Action: Check permissions on segment, contact Oracle Services.

I am not sure if the oracle account under which I am installing 9i has the right credentials, how can I check that? The problem might be something else though. Any help is greatly appreciated. Thank you.
