Automatically adjust memory pools and activity levels, also known as QPFRADJ, is a member of the performance category of i5/OS™ system values. You can use this system value to specify when to automatically adjust memory pools and activity levels. Activity level refers to the maximum number of threads that can compete for memory and processor resources (maximum eligible threads at the same time). To learn more, keep reading.

You may specify when to automatically adjust memory pools and activity levels. If you select to have the system adjust memory pool sizes and activity levels, you can specify that these adjustments occur at system restart (1), periodically after restart (2), or both (3). If you do not select system restart or periodically after restart, no automatic adjustment is done (0).
