Listener Threads (-N)

The Listener Threads (-N) adapter command can be used for ALE sources only when using the Launcher. Use this adapter command to specify to the listener to register multiple times at the gateway and to listen for incoming IDocs. To process large IDocs sent from the SAP ALE adapter, use this command. This adapter command may increase performance at the gateway by allocating more work processes (worker threads) to service requests. The recommended count for listener threads is a number equal to the total work processes of the SAP Application Server.
