Barry,
A while ago, when I wrote a script to do this for a site, I attempted to
login with a bogus userid/password and then checked for the Oracle error
message. Thereby, eliminating a security hole, and not "hugely" impacting
Oracle by logging in for a simple check.
Also, I was poking around Steve Adams's site and came across his script to
do this, which is more through. So I would check his site. This link
should take to the misc page on his website, then scroll down to the
bottom...

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.
