Re: Determining Oracle status

Barry,

Depending on your shell, start a timer (korn supports TMOUT). If you don't get a valid response within N seconds (trap the signal), you've got a problem.

Hi all,

I am trying to write a script in unix that determines if a specific oracle instance is available. I'm trying to avoid using the 'ps' command, so I thought the easiest method would be to connect via sqlplus - If it connects its up, if it doesn't then its unavailable. However, the problem is that when it isn't up, the script hangs and does not return anything - I think that this is because sqlplus by default gives you 3 attempts to logon, so even though the logon attempt failed, it is waiting for you to try again, so
unfortunately I'm not getting a failed return code. If anybody could tell me how to change this so that it only allows 1 login attempt before 'kicking you out' or whether there is a better method to finding out the status of an instance, I would be extremely grateful to hear
from you.

TIA for any responses.

Best Regards,
Barry.
