Viewing and setting huge-page memory values for AIX dedicated memory partitions

View and set values for AIX® huge-page memory allocation.

On systems that support huge-page (16 GB) memory allocation, you can set the current value in the huge-page memory table. On a new system, you must set this value initially to establish the huge-page memory pool. You must set the value when the managed system is in the powered-off state. If this value is already set, you must change the value to adjust for performance needs based on the applications that you are running and your logical partition configurations. You can also change the values set for the number of huge pages allocated to your logical partitions. Use this task to set or adjust the number of 16 GB pages for the huge-page allocation according to your needs.
Note: To change the values for logical partitions, you must shut down the logical partition. The new value takes effect when you restart the logical partition.

To set huge-page memory values for a logical partition, do the following:

  1. In the navigation pane, expand Systems Management > Servers.
  2. Select the server that has the logical partition you want to configure.
  3. In the work pane, select the logical partition for which you want to set huge-page memory values.
  4. Select Configuration > Manage profiles. The Managed Profiles window opens.
  5. Select the logical partition you want to configure.
  6. Select Actions > Edit The Logical Partition Profile Properties window opens.
  7. Click the Memory tab.
  8. Assign Huge Page memory for this partition profile and click OK.
