RE: AIX vs Solaris

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.

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.
