Using JFS2 filesystems with 10.2.0.2.0 (concurrent I/O)

Hi,

Just wondering if someone could clarify something regarding JFS2 and Oracle 10g on AIX 5.2:

Since with 10g we can enable Concurrent I/O on JFS2 at the file level, does this mean we don't have to mount the jfs2 filesystem with the cio option enabled?  The documentation says that with FILESYSTEMIO_OPTIONS set to "setall", it will enable concurrent I/O on JFS2 for all data file I/O.  And it says that the data files can reside on the same filesystem as the Oracle home directory.

Or do we still have to mount the jfs2 filesystem with the cio option enabled?

Howdy, Stranger!
