Greetings,

One of my system is p570, 4 procs, 16 GB RAM with Oracle 9iR2
installed.
AIX 5.2, ML 6
Before to use CIO on oracle FS, I configured AIO to start at boot
(minservers=20 ; maxservers per cpu=100).

Since I discovered CIO, I configured it on 2 FS (/oradata1 and
/oradata2) and changed the oracle parameter filesystemio_options from
asynch to setall

>From what I understand : if you configure setall on cio-fs, oracle uses
cio (and only in this case).

AIO consumes kernel processes.
So my questions are : is AIO still needed to be configured ? Does CIO
need AIO to be present or not ? Can I change the "STATE to be
configured at system restart" from AVAILABLE to DEFINED (smitty chaio)
?

Thank you in advance,
Wilfrid
