Hi,
Today morning when I came to work I saw that the database was down and the following error was logged in the alert file.

Tue Jun 12 03:45:55 2001
CKPT: terminating instance due to error 204
Instance terminated by CKPT, pid = 65

I started the instance and it started successfully, but my question is why did it fail and what does this error mean.

Please suggest.

Thanks
Anurag
