5.Enable PRM’s application manager if it is not already enabled:
#prmconfig -e APPL
Alternatively, enable all PRM resource managers using prmconfig
#prmconfig -e
Example: Grouping an application by its alternate names and functions
To place an application in the same group as its alternate names, add the application’s name to the list of alternate names. For example, to put the main database program in the group order_process, add it to the list of alternate names in the record, as shown below:
#PRM application records
/usr/bin/database::::business_apps,db_inventory,db_payroll /usr/bin/database::::order_process,db_orders,database
Example: Assigning a running application to another group
Assume the sales department purchased a new application called CustomerTrack to help them track their customer base. Because the application does not have a record, it runs in the group of the users that invoke it. Because everyone on the sales staff is assigned to the sales group, CustomerTrack runs in the sales group.
However, due to the importance of this application as a sales tool, the PRM administrator decides to assign it to the crit_apps group where it is assured sufficient resources.
The procedure to
1.Open the desired configuration file in a text editor.
2.Add an application record for CustomerTrack with crit_apps as the assigned group.
3.Configure PRM using
# prmconfig -k
4.Wait for the application manager to automatically move the processes. This will take no longer than 30 seconds, the default length of the application manager polling interval. Alternatively, move the processes yourself as discussed below.
a.Find the process ID for CustomerTrack using the ps command:
#ps -efP grep CustomerTrack
UID | PRMID | PID | PPID | C | STIME TTY TIME | COMMAND |
root | PRM_SYS | 4435 | 4220 | 6 | 15:16:21 ttyp2 0:00 | grep CustomerTrack |
advisor4 | sales | 4418 | 4220 | 4 | 15:11:18 ttyp2 0:00 | CustomerTrack |
b.Move the CustomerTrack process and all its child processes by process group PID to the PRM group crit_apps using prmmove:
# prmmove crit_apps -g 4418
5.Verify that CustomerTrack is running in the crit_apps group by using the ps command:
# ps -PR crit_apps
PRMID | PID | TTY | TIME | COMMAND |
crit_apps | 4418 | ttyp2 | 0:00 | CustomerTrack |
crit_apps | 4485 | ttyp2 | 0:00 | CustomerOrder |
crit_apps | 4492 | ttyp2 | 0:00 | Issue |
Removing an application’s group assignment
To remove an application record with a text editor:
