Thanks for all of your thoughts so far.... I am aware of the async I/O
requirements for Oracle, but never played with direct I/O. I will do
some
testing with this and see what I can find out, and post some any
findings
here for your reference.

I haven't got the PDFs handy, but I have a vague recollection that
direct I/O is enabled by default in the 5.1 server on AIX...

It should provide almost all the advantages of using raw volumes, and
IMHO, for TSM DB, log and stgpool volumes, is an excellent idea. I
wonder
if/when Oracle is going to support this?
