We had IBM come in and try to tune the depth queue - apparently there is some bug between their aix box and the hitachi san - they could only get a depth queue of 1 - whereas the sun box could go to a depth queue of 32.

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.

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.
