I had to do a shutdown abort to shutdown oracle fully. Then I connected internal and tried to start it up, it mounts the database but is not able to open it I get the error:
Ora 3114: end of file communication channel, then when I try to reconnect it gives me tns protocol adapter error, I have to again do a shutdown abort......, I rebooted the server to release memory and then tried to restart but no success. There are 3 other instances in the same server which are running ok.
Oracle is looking at the trace files but no response yet.

Thanx
