A belated response ...
You can't use dbverify either, with the filesystemio_options=setall option on a
jfs2 file system (which, as has been discussed, causes Oracle to use file-level
CIO). Not sure if the same restriction exists for jfs/DIO.

Subject: RE: CIO on AIX
I've been running with filesystemio_options=setall and no cio mount
option for 9 months with no problems. It sounds like the only problem
Louis reported was with running user-managed hot backups, but we never
do that and I can't really imagine why anybody would do it.
Louis, why don't you use rman?

- Brandon has 10g, no cio, param set to 'setall' and his lsoft showed
that files are opened with c_io.
- Louis has 10g, no cio, param set to 'setall' but he gets a crash.
Mounting the fs with cio fixes it.
- looks like safest way to go is have both enabled (cio and setall) on
9i and 10g.
