Cold start with openUTM
Before an application starts for the first time, you create the KDCFILE using the generation tool KDCDEF. After a regeneration of the KDCFILE or if the UTM application was terminated normally before, openUTM performs a cold start the next time the application is started. After the application has been started successfully, openUTM outputs the message:
K051 Successful cold start for application <appliname> under UTM V07.0A00 / operating-system-type
Warm start with openUTM
If a UTM application has been abnormally terminated, openUTM performs a warm start the next time this application is started. During a warm start, openUTM brings the KDCFILE into a consistent state. After a successful start, openUTM outputs the message:
K050 Successful warm start for application <appliname> under UTM V07.0A00 / operating-system-type
You should note that UTM-S and UTM-F differ in the scope of their restart functions. See also the openUTM manual “Concepts und Functions”.
