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
Appreciation is a wonderful thing;
It makes what is excellent in others belong to us as well.

The error suggests that there was an error reading the controlfile.

Hi,
oerr ora 204
00204, 00000, "error in reading control file '%s' (block %s, # blocks %s)"
// *Cause: Disk read failure of control file
// *Action: Check if disk is online, if it is not, bring it online and try
// warm start again. If it is, then need to recover disk.
If you can access an UNIX server, you can retrieve the signification of oracle-based errors:
just log as dba (belonging to the dba group), and type:
oerr 'module' 'err#'
for example, in your case:
oerr ora 204
cheers
