Is it a must to set MULTIPROCESSOR to 1 on a multiple CPU server even if
you only using 1 CPUVP and SINGLE_CPU_VP is set to 1?

Some posts on c.d.i say yes, some say no and the IDS docs do not give a
concrete answer.

Also, it has been said that when configuring ipcshm poll threads you
should configure 1 per CPUVP to load balance the polling work on all of
the CPUVPs. On HP/UX this can cause your number of shared memory
segments to be greater than the optimal value of 3. Anyone have any
thoughts on which is better, load balancing the polling work or keeping
the number of segments at 3?

Thanks,

MULTIPROCESSOR Specifies that you are running on a multiprocessor
computer

so I would set it to 1.

2. Not sure so I would benckmark. I would probably go with more Poll
threads. Which IDS version
are we talking about? The main problem is having more than 1 Virtual
Shared Memory Segment.
Pity HP designed a crap processor that does not handle more than 3
shared memory segments.

I though IDS merged the resident and 1st virtual segment under HPUX?
Can IDS 10 merge
shared memory message segments if you have more than one poll thread on
a CPU VP?

Another feature request? Are HP dropping PA-RISC in favour of Itanium?
I though HP-UX 11.23
is Itanium only?
