You can extend a DB2® database Control Center by using the plug-in architecture to provide additional function.
The concept of the plug-in architecture is to provide the ability to add items for a given object in the Control Center popup menu, add objects to the Control Center tree, and add new buttons to the tool bar. A set of Java interfaces, which you must implement, is shipped along with the tools. These interfaces are used to communicate to the Control Center what additional actions to include.
The plug-in extensions (db2plug.zip) are loaded at the startup time of the Control Center tools. This might increase the startup time of the tools, depending on the size of the ZIP file. However, for most users, the plug-in ZIP file, will be small and the impact should be minimal.
