You have a number of different options for terminating the UTM cluster application:
Shut down one node application, for instance using the command KDCSHUT GRACE.
Shut down all running node applications of the UTM cluster application, for instance using KDCSHUT GRACE, SCOPE=GLOBAL.
openUTM manual “Administering Applications”, Administration command KDCSHUT
Using WinAdmin/WebAdmin:
Terminate an individual node application or terminate a UTM cluster application with all running applications.
„WinAdmin Online Help“ or WebAdmin Online Help, Terminating an application
Using an administration program you have created yourself:
Terminate an individual node application or terminate a UTM cluster application with all running applications.
If only one node application is running, shutting down this last node application has the same effect as shutting down the complete UTM cluster application.
