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.

The minimum number of idle connection instances that a pool maintains for a database connection after the maximum idle time is met. If multiple database connections are associated with a PowerExchange Listener, PowerExchange determines the minimum number of connections to the PowerExchange Listener by adding the values for each database connection.

The maximum number of idle connection instances that a pool maintains for a database connection before the maximum idle time is met. If multiple database connections are associated with a PowerExchange Listener, PowerExchange determines the maximum number of connections to the PowerExchange Listener node by adding the values for each database connection.

Verify that the value of MAXTASKS in the DBMOVER configuration file is large enough to accommodate twice the maximum number of connections to the PowerExchange Listener node.

Enter 0 to specify an unlimited connection pool size.

Default is 15.

The number of seconds that a connection instance that exceeds the minimum number of connection instances can remain idle before the connection pool drops it. The connection pool ignores the idle time when the connection instance does not exceed the minimum number of idle connection instances.

If multiple database connections are associated with a PowerExchange Listener, PowerExchange calculates the arithmetic mean of the non-zero values for each database connection to determine the maximum idle time for connections to the same Listener.

Default is 120.
