you will find the underlying error by looking at the alert<SID>.log file, which is in the folder indicated by the bdump setting in the pfile/spfile.

It is never good when one of Oracle's background processes (PMON, SMON, DBWR, ARCH, etc.) terminate with an error.  This apparently happened right after you tried to do: "shutdown immediate;".  Is that correct?

You may have to look in the alert_[SID].log file or in the [SID]_dbw*.log file for more information, if you want to figure out what caused the ORA-00471 error.

I would try a "startup;" to see if that succeeds.  If it does, you may be OK.  But,it would be good to take a backup now just to be safe.

Hi,

this is what oracle recommends :

[oracle@ed-olraclin68a oracle]$ oerr ora 471
00471, 00000, "DBWR process terminated with error"
// *Cause:  The database writer process died
// *Action: Warm start instance
[oracle@ed-olraclin68a oracle]$

just restart the database.

good luck :)

As rbrooker suggested, just try re-starting again..
It could be very well due to some server issues.. If the error is persistent then its a serious issue.. If it is not replicated then it can very well be ignored!
