Does Oracle make a mistake in this doc?
hi
would any storage-DBA expert explain to me, please, this section of Oracle documentation:
http://download.oracle.com/docs/cd/E11882_01/server.112/e16638/iodesign.htm#i28823
?
I thought for DSS it's recommended to use larger RAID0 stripe's depths (simply : stripe size).
Here, it's written that, opposite, it is so with OLTP.
In example
for OLTP they say the stripe size is like:
n * DB_BLOCK_SIZE => (DB_FILE_MULTIBLOCK_READ_COUNT -1) * DB_BLOCK_SIZE
I assume (at least in my case), usually MBRC is more than 2.
and for DSS:
n * DB_BLOCK_SIZE

Then at the end of this section we find this hint:
