ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exi
Hello
I have Oracle 10 g express edition installed on windows server.
The server rebooted suddenly due to some problem
The client while trying to connect to oracle on this server started getting
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
When I tried to connect as sysdba on server it gave me error
ORA-01034: ORACLE not available and
ORA-27101: shared memory realm does not exist
I tried restarting services.
I tried rebooting server.
I also checked that Oracle_SID is not present in Mycomputer- properties - Advanced - Environment Variables.
How should I approach the problem?
Thank you very much
