A UTM application is started by calling the utmmain program. This program is the main function of the application and runs as a background process. utmmain creates the work processes (utmwork), the timer process (utmtimer) and, if required, network processes (utmnet, utmnets, utmnetssl) and printer processes (utmprint, Unix and Linux systems only). See also the openUTM manual “Concepts und Functions”.
A UTM application can also be started with a debugger for diagnostic purposes (see openUTM manual “Messages, Debugging and Diagnostics on Unix, Linux and Windows Systems”, section "Debugging UTM applications").
Please note that the utmmain program must always be started under the application directory (filebase).
