dbwr_io_slaves on Oracle 9i

[Bigcat37]

Hi

Burleson (the famous) said:
"...
# Use dbwr_io_slaves for applications that are not write intensive and run on operating systems that support asynchronous I/O.

# Use dbwr_io_slaves on platforms that do no support asynchronous I/O.
..."

But isn't contradictory !?
what do you think about it guys ?

dbwr_io_slaves is less CPU intensive than multiple DB writers, so if you are not doing much writing, (static DB) they save CPU resources, even though they are less capible.

And of course, if you can't use mutltiple DB writers (no asynchronous I/O) they are the best choice in any case.

I tried to remain child-like, all I acheived was childish.
