Exchanging shared objects with LOAD-MODE=STARTUP

When exchanging application parts generated with LOAD-MODE=STARTUP, the work process continues running. The shared object is unloaded and the specified version is loaded dynamically.

This program exchange can be executed simultaneously by several work processes of an application. During the program exchange, different states of the application program are loaded in the work processes of the UTM application. Each work process of the application implements the requested program exchange when it has finished processing the current job. A UTM message is output to indicate that the program exchange process is complete.

No further program can be exchanged until this program exchange is concluded. Another KDCPROG call will be rejected by openUTM.
