PRM configuration planning
Identifying resource use
Chapter 380
• If response times are appropriate for representatives of each
conflicting group.
Step 2. Set up a preliminary configuration
With the preliminary data you have gathered, set up some PRM groups
and assign them CPU, memory, and disk bandwidth resources, users,
and applications, then observe system usage to determine:
• The PRM groups you need to match your configuration model.
• The initial and alternate PRM groups users need access to.
• The PRM groups that applications should be placed in to achieve a
desired level of performance.
Step 3. Determine the resource allocations
To decide on the final resource allocation for your PRM groups:
1. Determine the allocations necessary for each group to get an
appropriate level of performance.
2. Separate out the highest level user groups.
3. Determine which user groups could demand lots of CPU, memory,
and disk bandwidth resources—if not limited.
4. Extrapolate from current data to identify user groups that will have
increased resource needs in the future.
5. Determine the maximum CPU, memory, and disk bandwidth
resources that each group should get at peak load.
Step 4. Make adjustments
After a trial period using the initial configuration, make adjustments to
the configuration based on the following:
1. Collect data again.
2. Does the data reflect what you want and expect?
3. Are there any new conflicts?
4. Are there any new user or business demands?
5. Are there specific times when you might benefit from changing your
configurations regularly?
