Multi-Trans Schedule Type

The multi-trans schedule type causes a transaction program to remain active between inbound conversation requests, with its resources available. The first inbound request starts the multi-trans TP. Subsequent requests can use the same instance of the transaction program and avoid the overhead of repeated resource allocation and deallocation.

Multi-trans processing is appropriate only for certain types of transaction programs. As a general rule, when properly implemented, multi-trans processing is appropriate for transaction programs that are requested often by multiple users, that have an initial high resource overhead, and that finish processing comparatively quickly.
