HP-UX
does support async I/O. /you only need to include /dev/async in the
kernel.
IBM
and SUN support async I/O, too. Linux does not.
John,
You should be able to
tune the SCSI device queue depth; I’ve done this on HP-UX and Solaris systems,
but haven’t had to under AIX yet. I don’t have an AIX system handy to
verify this, but I’m 90% sure you can do it. AIX also supports async I/O
where HP-UX doesn’t (not sure about Sun), which is a big win in an Oracle
environment.

AIX vs Solaris
We had an aix box and ended
sending it back and going with sun - only because we had a hitachi san and
there seems to be a bug between ibm and hitachi - something about depth
queue.

Hello,
What are the major differences between AIX
and Solaris regarding operating system features?
We are planning a
new machine purchase; currently we are on a Sun machine running Solaris,
but IBM is making a strong proposal to management (meaning significantly
less cost), and we are wondering what would need to be changed. We use korn
shell scripts extensively, and features such as crontab, background
processing, the sqlplus <<EOF ... EOF construct (not sure what this
is called). I'm fairly sure these are standard in most flavors of unix, but
I have never had contact with AIX. Does anyone know what features differ
between the two OS's?
If we went with Solaris, we would go with Solaris
9 running Oracle 9.2 on a Sun 4800.
Thanks for any
responders.
