Kevin, Nothing wrong with just going with the defaults unless you actually discover there is a problem with DBWR IO. I would suggest some clear goals and benchmarks. Play with async_io, dbwr_io_slaves and other dbwr parameters. Run a performance monitoring tool during the tests and get some real comparisons. I think you can also hook up statspack to 8.0.5. Might even be DBWR is not the bottleneck. - Ethan - http://www.geocities.com/epost1 <http://www.geocities.com/epost1> -----Original Message----- Sent: Thursday, August 30, 2001 9:54 AM To: Multiple recipients of list ORACLE-L I am trying to figure out how to configure the DBWR_IO_SLAVES parameter on our system. We are running 8.0.5 and are using Network Appliances as our file storage. For those who do not know Network Appliances, they have a file system called the WAFL (Wrate Anywhere) file layout. This means that you really do not configure individual drives or mount points based on individual physical drives. The OS takes care of placing the data where it wants to. Its prety quick and is working out well for Oracle. But, since there are no specific drives to count up, how do you come up with a reasonable DBWR_IO_SLAVES value on this system ??
