Conﬁguring PRM

Chapter 7112

Removing groups/CPU allocations

To remove group/CPU allocations with a text editor:

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

Step 2. Remove the line corresponding to the group/CPU record you wish to

remove. If the group is a parent group, you will need to remove all the

child groups ﬁrst. Group/CPU records have one of the following forms:

GROUP:PRMID:SHARES:[MAX]:

GROUP:HIER:SHARES::

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

Step 3. Remove or modify application, memory, disk bandwidth, or user records

that referenced the PRM group removed in Step 2.

Step 4. Save the ﬁle and exit the text 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.)

Step 6. Enable PRM’s CPU manager if it is not already enabled:

# prmconfig -e CPU

Alternatively, enable all PRM resource managers using prmconfig -e

without any additional arguments:

# prmconfig -e
