Hi, listers

A bit broad question... Is there a way to find out (by querying V$ views) what would be the optimal value for db_writer_processes parameter? As changing this parameter requires restart of the database, I have to provide proper justification (ITIL process) for this change.

Oracle, SLES 10.1 64 bit, OCFS2, db_writer_processes=1, filesystemio_options=directio, db_cache_size currently at 16GB, 4 dual core cpu server, RAM 32GB
