Sous-processus Arbortext PE Pool Management
A subprocess pool is a collection of identical Sous-processus Arbortext PE. Each Sous-processus Arbortext PE pool has a unique name, a collection of attributes that describe the pool's behavior, a set of parameters that are passed to every Sous-processus Arbortext PE in the pool, and a collection of rules that determine which HTTP requests can be processed by Sous-processus Arbortext PE in the pool.
Support for multiple Sous-processus Arbortext PE pools offer two major advantages:
• Pools of Sous-processus Arbortext PE can have different parameters, making it possible to have groups of Sous-processus Arbortext PE with different behaviors.
• Sous-processus Arbortext PE pools can be configured to reserve performance capacity by ensuring that requests of a particular type don't consume all available Sous-processus Arbortext PE.
Each Sous-processus Arbortext PE pool provides the following capabilities:
• ensuring that a configured minimum number of Sous-processus Arbortext PE are running.
• starting additional Sous-processus Arbortext PE (up to a configured maximum number) upon request.
• limiting the number of Sous-processus Arbortext PE that can be used to process queued transactions.
• terminating any Sous-processus Arbortext PE that fails to respond to a request from the Arbortext PE Request Manager after a configured period of time.
• terminating Sous-processus Arbortext PE that have been idle for more than a configured maximum period of time.
• terminating an Sous-processus Arbortext PE and starting a new one (between requests to avoid disruption of processing) if an Sous-processus Arbortext PE has been running for more than a configured maximum period of time.
Terminating an Sous-processus Arbortext PE avoids possible consumption of resources that could accumulate over time.
• returning messages that a request has failed after a configured interval if all Sous-processus Arbortext PE are busy and the maximum number of Sous-processus Arbortext PE are running.
