OpenTP1 enables jobs to be executed efficiently by running UAPs in multiple processes. On a node, one UAP processing is executed in multiple processes to increase efficiency of the server system. This facility is called multiserver. It also enables UAPs having the same name to be placed on multiple machines so that service requests can be handled on any node. This facility is called internode load-balancing facility. For details of the relationship between UAPs and processes to be executed, see 1.3.6 User server load balancing and scheduling.
