The maxIdleInterval Attribute
This attribute specifies the number of seconds after which an Arbortext PE sub-process will be terminated if it's not allocated to serving a request. Termination only occurs if more than the minimum number of Arbortext PE sub-processes are running. The default value 0 disables termination.
When the request load is sporadic, consider the delay associated with startup and initialization each time the load increases. Disabling this attribute optimizes the ability to service requests and avoids the overhead associated with repeated startups that can delay fulfilling the request. Though an Arbortext PE sub-process consumes a certain amount of memory, it's still a small penalty to have it running when it’s not in use.
