Re: Solaris - DBWR process chewing up CPU Time

This could be because you are
doing too much writing and are
also running async I/O.

It would help if you could quantify
'chewing up' as a percentage of
CPU. Look at v$filestat for the number of
writes per file, look at alert log
for frequency of checkpoints,
look at db_files compared to actual
number of files.
