Managing memory
Now we have management of processors in shared-processor partitions, we will
move on to managing memory. Before continuing, you should stop the PLM
server instance.
In this second example, we will configure PLM to manage the configured
memory of two dedicated processor partitions: app_server and db_server.
Because PLM cannot manage different processor types within the same group,
we must create a new group. This new group can either be incorporated into the
existing PLM policy or we could create a new PLM server instance to manage it.
In this example, we will choose the first option to show the management of two
groups from a single PLM server.
The two dedicated processor partitions are configured identically on the HMC.
This is shown in Table 6-6.

Resource Min Desired Max
CPU 1 1 4
Memory (MB) 512 512 3076
The configuration steps are:
1. Edit the existing PLM policy file.
Choose the Edit a Policy File from the main PLM window. This produces a
window, as shown in Figure 6-17. Type in the file name of the previous policy
file or navigate to it using the Browse button. Click OK, which pops up the
Edit Policy File window.
