The CONNECTION-LIMIT parameter defines the maximum number of transport connections to be used in the execution of file transfer requests. Since the processing of a request always requires a new transport connection to be set up, CONNECTION-LIMIT also defines the maximum number of requests the system can process in parallel.
A third of the connections is reserved for outbound requests and a third for inbound requests. The remaining third can be used for inbound or outbound requests as required. You may therefore have to increase the value of CONNECTION-LIMIT to achieve the required throughput to your openFT partners.
Higher CONNECTION-LIMIT:
increased data throughput
better use of potentially underutilized processor capacity.
Lower CONNECTION-LIMIT:
reduced load on the local system and network, and hence less or even no impact upon interactive operation.
