In distributed processing, multiple program units in various partner applications are used to process a job. A program unit can be addressed by a client (terminals or client programs), from the application’s own programs or from other applications. The program unit has therefore to decide independently from the partner which task to process, to whom it sends a message, and whether or not it has to terminate a distributed processing.
For this reason, openUTM provides a range of information about the communication partner and the current communication status. This information can be evaluated and used for communication control. For a description of this information refer to the sections "Programming aids" for LU6.1 and "Programming aids" for OSI TP.
