In order to generate a new UTM application or adapt an existing UTM application, you must first define the application configuration using KDCDEF control statements, and then use the KDCDEF generation tool to generate the UTM components KDCFILE and KDCROOT from which the UTM application program is created. For further information, see "Introduction to the generation procedure".
You can also modify the configuration of an application dynamically during operation. To do this, the RESERVE statement can be used during generation to reserve certain table locations for UTM objects. You can thus insert or remove clients, printers, user IDs, and services, KSETs, LTACs, CONs and LSESes in the configuration “on-the-fly” without affecting availability. The dynamic entry of objects is described in detail in the openUTM manual “Administering Applications”.
By issuing a CREATE-CONTROL-STATEMENTS statement during the KDCDEF run, you can read out the configuration information defined in the KDCFILE of a dynamically configured application, and convert this information to control statements. This function is known as inverse KDCDEF. The control statements which are generated in this way are written to a file which you can re-use directly as the input file for the KDCDEF run. For more information, see "Inverse KDCDEF".
