HP PRM & WLM Config & Use

[Nelson Laracuente]

We have an RX4640 that needs some tweaking of memory and CPU usage. We want to implement HP PRM & WLM to do the capping of these. I have loaded trial versions of these softwares to a test RX1600. I am having a heck of a time trying to figure out how it is configured and how it is suppose to work. I have several PDF manuals and to me they are not helpful. Short of actually taking the class HP offers, any ideas where I can find a document that covers step by step installation, configuration and usage of these features??? Thank you.

Hi Nelson,

Try some of the links and attachments in the below thread. Hopefully one of them can help you out.

The link you sent me took me to another page with three links which were of no help. Thanks.

Following 2 white papers would give you an idea of steps for PRM and WLM configuration.

http://h20338.www2.hp.com/hpux11i/downloads/prm.overview.pdf

http://h20338.www2.hp.com/hpux11i/downloads/wlm.gettingstarted.pdf

Integrating of both products would consist of including PRM structures in WLM as mentioned in the documents.

Take a look at this as well.

Thanks for the help. I think I may need to contact someone at HP for step by step guidance. I have most of the pdf manuals and none are helpful.

Hi Nelson,

The other folks posting have given links to good getting started documentation. If you
prefer to start with example configs then
copy and edit (a style of learning many
use), then you can see many WLM config examples
on the system where you have WLM installed.
Check /opt/wlm/examples/wlmconf
and, for specific applications, the
/opt/wlm/toolkits/*/config
directories.

Below is a listing:

Thank you Bryan.

If you simply want to split CPU resources between some systems... A simple PRM config might be what you need...

You probably have a file named /etc/prmconf.
Take a look in this file, as it contains a lot of comments that might explain a bit.

Here is an Example on a stripped /etc/prmconf that split CPU resources between 3 systems + Others (unassigned processes).

This example split based on process owner (username).

# Groups and shares
OTHERS:1:20::
SYS_A:2:40::
SYS_B:3:20::
SYS_C:4:20::
# Defined users and
# which PRM group they should belong to
root::::(PRM_SYS)
daemon::::OTHERS
bin::::OTHERS
sys::::OTHERS
adm::::OTHERS
uucp::::OTHERS
lp::::OTHERS
nuucp::::OTHERS
hpdb::::OTHERS
nobody::::OTHERS
www::::OTHERS
smbnull::::OTHERS
a_user::::SYS_A
a_oracle::::SYS_A
b_user::::SYS_B
b_oracle::::SYS_B
b_apache::::SYS_B
c_user::::SYS_C
c_oracle::::SYS_C

See man prmconfig and related prm stuff.

Thank you everyone for your help and suggestions. I will contact HP for the set up of this. I have read the manuals and tried the suggestions but I cannot get this thing to work. I will proceed to close this event. Thank you again everyone.

[Nelson Laracuente]

Cannot figure this out. Contacting HP. Closing event.
