This optional attribute specifies whether the Sous-processus Arbortext PE is available for taking requests. The default value is yes. If enabled set to no, the Sous-processus Arbortext PE pool is ignored and it doesn't start any Sous-processus Arbortext PE regardless of its parameter settings. You can set enabled to no to temporarily disable a pool without needing to delete the pool entry from the e3config.xml configuration file.
