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

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).</p>
