Memory utilization too high
I"m quite new in HPUX, as you can see from the attachment, the memory utilization is too high (98-99%), can someone please guide me how to check what process/things is causing this?
Thanks!

Re: Memory utilization too high
TOOLS
Best tools to use to analyse memory usage on HP-UX are Glance (license required, although you should be able to get a trial version from your account manager) and the kmeminfo tool (if you have a support contract with HP, open a support case to request the tool).
SUPPORT ARTICLE
There is a pretty good support article available with the title "HP-UX Operating Systems - How to Account for Memory Usage on an HP-UX System". If you have linked a valid support agreement to your ITRC account you should be able to search for it here on ITRC:
http://www11.itrc.hp.com/service/james/home.do
KNOWLEDGE ON DEMAND
There is also a video available on HP's Knowledge on Demand website that has quite a lot of information regarding performance/CPU/memory issues:

ITRC FORUMS
This thread below is also a good start:

Re: Memory utilization too high
As for processes, what does top and ps(1) show for process memory sizes?

Re: Memory utilization too high
it could be ok.
It seems that 20-25% is "B" = Buffer cache or File Cache.
With this command you could see the ram allocation !!
"UNIX95= ps -ef -o vsz,ruser,pid,comm,args|sort -rn |more"

Re: Memory utilization too high
You may want to reduce your buffer cache value: dbc_max_pct(5)
>total 32768 12613 20155 38%
You aren't using that much of your swap. Was this taken during the same time glance said you were using 99% of memory?

Re: Memory utilization too high
Your swapinfo -tam doesn't contain a memory line. Something is terribly wrong, you should set swapmem_on(5) to on. You appear to be on 11.23.
-> You mean the physical memory is not working? There is a hardware-RAM issue last week, HP engineer changed a new RAM. swapmem_on is to "TURN ON" this?

Re: Memory utilization too high
No, just somebody didn't configure the kernel parm swapmem_on to on.
