HELP!
I am simply out of ideas. About every 3 days or so our production DB shuts down. We are running Oracle 8.1.7 on Windows 2000. I thought it was backup related, but it's shutting down even when no backup is running. Somehow the controlfile is becoming locked and not released. Below is the info from the alert file and trace file. Any help would be greatly appreciated because I am officially stumped!

I would start by replacing 'D:ORACLEORADATAPRISMPA2CONTROL01.CTL' with one of your other control files if this one keeps causing the problem. This would be to make sure your control file isn't corrupt. You would do this by:

Note: all control files are the same so you can copy them.

1. shut it down
2. rename CONTROL01.CTL to CONTROL01.CTL_OLD
3. copy CONTROL02.CTL to CONTROL01
4. start it back up.

If you continue to have the problem make sure there isn't another database using the same file/directory. If so fix it. If neither of these options fix the problem call Oracle Support.

Hi,
A better way would be use a util called nthandle from www.sysinternals.com. It's free and will show which program(s) have the file open. If you find it's only Oracle. i.e the other programs closed down already then you would have to audit the file.

I also have this problem. Oracle 8.0.6/NT
plenty of disk space, baseline is about 1/3 the total physical mem. It's driving me nuts.
thanks and all the best,
John
