Conﬁguring and enabling PRM on the command line

Conﬁguring PRM

Chapter 7 119

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

# prmconfig -e MEM

Alternatively, enable all PRM resource managers using prmconfig -e

without any additional arguments:

# prmconfig -e

Adding/modifying shared memory allocations

To add or modify a shared memory record, follow these steps:

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

Step 2. Using the syntax shown below:

#!SHARED_MEM:{PRMID|GROUP}:MEGABYTES

and explained in the section “Memory record syntax” on page 113:

a. Add or modify a line specifying a PRMID or group name for an

existing group.

b. Specify the size of the shared memory allocation in integer

megabytes.

Step 3. Save the ﬁle and exit your editor.

Step 4. Load the conﬁguration using one of the commands below.

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.)
