connected to idle instance
Hi,
I am a DBA. I have oracle10 R2 in our Acc environment. Today after login as oracle user when connect through SYS I got a message "connected to idle instance". Then when I tried to shutdown it gives the same message and when tried to startup with parameter file in the correct location(permission and location checked twice) it gives me "File can not be opened" when the file is not corrupt and the oracle processes are running(run ps -ef| grep -i oracle) . Is there any reason why it happened?
