Enables connection pooling. When you enable connection pooling, each connection pool retains idle PowerExchange Listener connection instances in memory. When you disable connection pooling, the DTM process or the Data Integration Service process stops all pooling activity. To delete the pool of idle connections, you must restart the Data Integration Service.
Default is enabled for DB2 for i5/OS and DB2 for z/OS connections. Default is disabled for Adabas, IMS, Sequential, and VSAM connections.
