Exchanging programs during operation

openUTM offers two different methods for exchanging programs during operation.

• Exchanging the entire application program using the KDCPROG tool and the administration command KDCAPPL or an administration program that KDCADMI calls with the KC_CHANGE_APPLICATION operation code.

• Exchanging shared objects, i.e. parts of the application program, using the administration command KDCPROG or an administration program that KDCADMI calls with the KC_MODIFY_OBJECT operation code and KC_LOAD_MODULE object type.

The two methodes can be mixed, i.e. an application containing shared objects can also be exchanged as a whole. Both methods are described below.
