Hi, I've installed Oracle 9i on a Red Hat AS 2.1, but after the installation, when running the Database Configuration Assistant gave this error:

ORA-03113: end-of-file on communication channel

I found an installation guide on http://www.puschitz.com and it recommends you, when this error comes up , to remove the shared memory segments owned by oracle, and i did so, it just couldn't remove on , which chmod was 777..after that i retry the Database configuration assistan and it failed again but telling me a different error happened:

ORA-12571:TNS:Packet writer failure....

And i tried again and got the same error i got in the first place...and so on, and so on....

What can i do????

thanks...

Mario
