Changing the memory weight of a shared memory partition
You can use the Hardware Management Console (HMC) to change the memory weight of a logical partition that uses shared memory (hereafter referred to as a shared memory partition). Changing the memory weight changes the probability that the shared memory partition receives physical memory from the shared memory pool in relation to other shared memory partitions.
A Linux shared
memory partition supports changing the memory weight only if the DynamicRM
tool package is installed on the Linux shared memory partition.
To download the DynamicRM tool package, see the Service and productivity tools for Linux on POWER® systems Web
site.
To change the memory weight assigned to the shared memory
partition, complete the following steps from the HMC:
- In the navigation pane, expand .
- Click the server on which the shared memory partition runs.
- In the work pane, select the shared memory partition to which you want to add or remove logical memory.
- From the Tasks menu, click . The Add/Remove Memory Resources window is displayed.
- In the Memory Capacity Weight (0–255) field, enter the memory weight that you want to assign to the shared memory partition.
- Click OK.
Changing the memory weight of a shared memory partition is
temporary and is not reflected in the partition profile. The new memory
weight that you assigned to the shared memory partition will be lost
the next time you activate the partition profile. If you want to save
the changes that you made to the memory weight of the shared memory
partition, either change the partition profile or save the logical
partition configuration to a new partition profile.
