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