Demands are being made of OLTP applications to the effect that it should be possible to change configuration data dynamically in order, for example, to add new users or services to an application, without interrupting the running of the application.
In a UTM application, configuration data such as information on user IDs, communication partners, buffer sizes, etc. is initially specified statically when the application is generated. openUTM offers powerful tools and interfaces that allow you to change the configuration data while the application is running.
The graphical administration program WinAdmin offers a complete, Java-based solution for dynamic configuration. WinAdmin allows you to change the generated application parameters or add or delete generation objects from any Java platform (e.g. user IDs or connections to partners). You will find more information on WinAdmin on "Simple, user-friendly application programming" and "WinAdmin graphical administration program".
The WebAdmin component provides a web-based user interface for the administration of UTM applications on all platforms. The scope of functions provided by WebAdmin is similar to that found in WinAdmin. For further information on WebAdmin, see "Graphical administration with WebAdmin" and "WebAdmin graphical administration program".
The KDCADMI program interface allows you to create programs for dynamic administration that are designed to match your own requirements as closely as possible, in order, for example, to schedule specific changes and have them run automatically. You will find more information on this on "Administration program interface".
The UTM tool KDCUPD allows you, after you have regenerated your UTM application, to transfer user data and administration information of the application to the new configuration. KDCUPD is used when fundamental changes have to be made to the generation or when changing to a different version of UTM. When KDCUPD is used the following applies:
The running of a standalone application is briefly interrupted. After this, all the users can resume their work at the position at which they were previously interrupted.
In the case of most changes, UTM cluster applications can continue to run without interruptions since the individual nodes only have to be interrupted one after the other.
