Hi gang.

I haven't seen this one discussed anywhere and can't really find any references
to it that are worth repeating.

Does anyone have any information on optimal file system block sizes for FRA?
As in: the area where one keeps RMAN backups and archived redo log backups?

Specifically, in my case: in 10gr2, 11gr2, Aix 5.3 and 6.1, using jfs2.

I've got my development node with an FRA file system with 512 byte block size.
And production is on 4096 - max for jfs2.

I haven't been able to prove conclusively that one is better than the other for
normal RMAN backup/restore operations.

Any accumulated wisdom/advice/experience on this?

Nope: I couldn't find a button for this in OEM or grid, either... Received on Sun Mar 27 2011 - 23:41:24 CDT
