in order to access metalink you have to have a CSI number. Whomever bought Oracle at your shop would have this information. Simply goto http://metalink.oracle.com and register an account there. It takes all of about 5 minutes to do.
If you don't have a CSI number reply back here and I'll cut and paste the note.
Oracle it's not just a database it's a lifestyle!

You can only have as many dbwrites as you have db_block_lru_latches. Check this parameter and increase through your init.ora if necessary. However, bumping your dbwrites past 2 on a 2 cpu box will make them compete with each other if you in fact dbwriter can't get enough CPU already AND your on non-async filesystems.
