Conﬁguring and enabling PRM on the command line

Conﬁguring PRM

Chapter 7120

Step 5. 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

Removing private memory shares

To remove a memory record manually:

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

Step 2. Remove the line corresponding to the memory record you wish to remove.

Memory records have the following form:

#!PRM_MEM:{PRMID|GROUP}:SHARES:[MAX]:::[[IMPORT]:[EXPORT]:]

Step 3. (Optional) Adjust the memory shares of the remaining records to ensure

their resource allocations are as desired.

Step 4. Ensure there is still a one-to-one correspondence between memory

records and group/CPU records if there are any memory records still

present in the conﬁguration.

Step 5. Save the ﬁle and exit the text editor.

Step 6. 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 7. Enable PRM’s memory manager if it is not already enabled:

# prmconfig -e MEM
