This optional attribute specifies whether the Sottoprocesso Arbortext PE is available for taking requests. The default value is yes. If enabled set to no, the Sottoprocesso Arbortext PE pool is ignored and it doesn't start any Sottoprocessi 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.
