Before you start a UTM application, you must always ensure that the following files exist, as they are essential for the operation of the UTM application:
the KDCFILE
The system files SYSOUT and SYSLST are always present, but should be assigned to real, process-specific files.
the system log file SYSLOG
the user log file(s) USLOG (optional)
all program and object module libraries from which modules should be loaded dynamically at startup and during operation of the application
KDCFILE, USLOG and SYSLOG (if used without a link name) have the prefix filebase (=base name of the UTM application). You must specify filebase in the start parameters. The name filebase is defined when creating KDCFILE with the generation tool KDCDEF, see openUTM manual “Generating Applications”, control statement MAX...,KDCFILE=filebase.
