ORA-01034: ORACLE not available ORA-27101?
I have the following error, when i try to retrieve data from oracle database. It was working fine all these time, but all the sudden i got this message. Andy Idea, how to fix this. I am posting this question I am using linux.
And I am not sure how to check my ORACLE_SID value. Does any one knows how to check the oracle sid value? Command for that..
Any hints or Ideas;
