SHMEM_MAGIC on HP

 SHMEM_MAGIC on HP
Hi - I'm posting this query for someone that doesn't have access to this
newsgroup..

We need to be able to address additional shared memory on our HP V2500
platform. We are running HP_UX 11 64 bit os and 32 bit informix
7.31.UC5.

I understand that by using SHMEM_MAGIC, we can address up to 2.75Gb of
shared memory? Has anybody done this? Is it
stable? What are the pitfalls?"

thanks,

rj

You would probably do better posting this question to comp.sys.hp.hpux

Yes, with SHMEM_MAGIC you can have sum of SM segments up to 2.75Gb in size
(instead of HP standard 1,75 Gb limit). I've got some info how to do that on
HP 10.20, things on HP-UX 11.0 should be definitely different.

I'd recommend you to contact HP guys (have you paid some money for
support?). Exact scenario depend on your OS patch level (recommended patch
bundle + critical patches + patches required for SHMEM_MAGIC).

BTW, according to HP, all 32-bit apps (including Informix) running on 64-bit
OS would be at least 10% slower due to address translation involved in
converting 64 bit to 32 bit and back again , and vice versa.

Hope this helps,
Sergey
