2. Remove the line corresponding to the shared memory record you wish to remove. Shared
memory records have the following form:
#!SHARED_MEM:{PRMID|GROUP}:MEGABYTES
3. Save the file and exit the text editor.
4. 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 [-fconfigfile] {-s | -c}
To keep the existing assignments of users, processes, and groups, use the command:
#prmconfig -k [-fconfigfile] {-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.)
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
Isolating private memory for a group
To isolate memory for a group, follow these steps:
1. Open the desired configuration file in a text editor.
2. Using the syntax shown below:
#!PRM_MEM:{PRMID|GROUP}:SHARES:[MAX]:::[[IMPORT]:[EXPORT]:]
and explained in the section “Memory record syntax” (page 59):
a. Find the memory record in the configuration file you wish to modify.
b. Set the EXPORT and IMPORT fields to zero.
NOTE: You cannot set EXPORT to 0 for the OTHERS group.
3. Save the file and exit your editor.
4. 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 [-fconfigfile] {-s | -c}
To keep the existing assignments of users, processes, and groups, use the command:
#prmconfig -k [-fconfigfile] {-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.)
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
