The PROCESS-LIMIT parameter defines the maximum number of tasks that may be used for processing file transfer requests. The number of file transfer requests per task handled simultaneously can be expressed as follows:
CONNECTION-LIMIT / PROCESS-LIMIT
CONNECTION-LIMIT is the maximum number of parallel transport connections that can be used to execute requests.
If the PROCESS-LIMIT value remains fixed and the value of CONNECTION-LIMIT is increased, then proportionately more transport connections are available for each task and therefore more requests can be processed per task. The reduction of the PROCESS-LIMIT value where CONNECTION-LIMIT remains constant achieves the same effect. If the value of the quotient is reduced (by reducing CONNECTION-LIMIT or increasing PROCESS-LIMIT), a smaller proportion of transport links is available per task. Consequently, fewer requests can be processed per task.
If the number of requests awaiting processing exceeds the value of the quotient but the number of tasks assigned has not reached the PROCESS-LIMIT value, then another task is initiated.
Higher PROCESS-LIMIT:
fewer wait times for input/output
better use of potentially underutilized computer resources
Lower PROCESS-LIMIT:
reduced load on the local system
