Setting huge-page memory values for AIX dedicated memory partitions

On managed systems that support huge-page memory, you can use the Hardware Management Console (HMC) to set the value for the huge-page memory pool. You can also specify values for the number of huge pages to allocate to logical partitions.

Using huge pages can improve performance in specific environments that require a high degree of parallelism, such as in DB2® database. You can specify huge-page memory that can be used for the shared-memory buffer pools in DB2. For logically partitioned systems, you can specify the minimum, wanted, and maximum number of huge pages to assign to a logical partition when you create the logical partition or partition profile.

To set the huge-page memory values, the system must be in the powered-off state. The new value takes effect when you restart the system.
