Performance system values: Automatically adjust memory pools and activity levels
The Automatically adjust memory pools and activity levels system value is also known as QPFRADJ. 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).

What can I do with this system value?
You can 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 at system restart or periodically after restart, no automatic adjustment is done (0).
