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