Re: Determining Oracle status

Don't know how to change it to only 1 login attempt. But I would do a "select sysdate from dual;"
after connect via sqlplus. This way if the 1st login failed, the SQL statement will cause the next two
attemt fail as well and sqlplus will exit.

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.
