Exchanging an application with shared objects

The entire application can be exchanged with the administration command KDCAPPL PROG=NEW. The exchange can be done via the PROG file generation directory that you must prepare with the KDCPROG tool (see section "Requirements for exchanging an application") or UTM loads the application program utmwork directly from the base directory.

In both cases, each work process of the application is unloaded in succession and then loaded dynamically when the entire application is being exchanged. In the dynamic loading process, the new versions of the shared objects are loaded. To minimize the interruption to the operation of the application, the exchange is only performed by one application work process at a time.
