 Restart WLM / MeasureWare

Restart MeasureWare if it was running before the PRM upgrade/installation:
# /sbin/init.d/mwa start
Preparation
Your PRM configuration should reflect some aspect of your business priorities. You may choose
to configure your system based on how much each user group funds the system (budget model).
Alternatively, you may configure the system to reflect the priorities of the applications that run
on it (application priority model). Perhaps, you will devise another configuration model.
In general, when planning a PRM configuration, you should determine:
1. Your total available memory, number of cores, number and throughput speed of disks.
2. Who the users are and what their needs are.
Whatever model you choose, it is important to identify the configuration model you want before
you begin to identify resource use and assign PRM groups and resource allocations.
The following sections help you to answer the following questions:
 Which applications should run under control of PRM?
 Which processes belong to those applications?
 What should be the names of the PRM groups?
 Which of the system resources (CPU, MEMORY, DISK) should be controlled by
PRM?
 Which entitlements should each PRM group have?
Dividing Processes into Groups
