Connect locally -- logged on as oracle? If so, try a different user account. Two possibilities immediately come to mind - one is that the root chmod to run the oracle.exe as oracle was not done, so it can't access the shared memory, the other is that there is a general problem with the permissions created on the shared memory segments. If you're logged on locally as oracle, that would mask either of these two problems. Of course I didn't even look up your error numbers and this could be something completely different.

When I try to connect remotely I receive these errors. I can connect locally without problems and if I run ipcs I see the shared memory. I'm running Oracle 9.2.0.6 on RedHat EL 3 AS Any help is appreciated. Sincerely, Magnus Andersen
