Conﬁguring PRM

Chapter 7110

• An FSS PRM group mailserver (PRMID 5) with 10 CPU shares.

•Amanagement PSET PRM group with two cores assigned. The

speciﬁc cores assigned are Core 3 and Core 4.

Adding/modifying PRM groups and CPU allocations

To add or modify a group/CPU record, follow these steps:

Step 1. Open the desired conﬁguration ﬁle in a text editor.

Step 2. Add or modify a line specifying the group name, PRMID, HIER or PSET

keyword, and CPU allocations. Use the syntax shown below:

GROUP:PRMID:SHARES:[MAX]:

GROUP:HIER:SHARES::

GROUP:PSET:::[CORES]:[CORE_LIST][:PSET_ATTR]

and explained in the section “Group/CPU record syntax” on page 105.

Step 3. Add or modify memory and disk bandwidth records as needed. For more

information, see “Controlling memory use” on page 113 or “Controlling

disk bandwidth” on page 123.

Step 4. Save the ﬁle and exit your editor.

Step 5. Load the conﬁguration using one of the following commands:

To initialize, moving user processes to the owners’ initial groups and

moving applications to their assigned groups, use the command:

# prmconfig -i [-f configfile] {-s | -c}

To keep the existing assignments of users, processes, and groups, use the

command:

# prmconfig -k [-f configfile] {-s | -c}

Use the -f configfile option to specify a ﬁle other than the default

/etc/prmconf. The -s option displays warnings regarding the

conﬁguration ﬁle. (The -c option displays a subset of the -s warnings.)
