Custom services

A custom service provides the ability to plug into a WebSphere application server to define a hook point that runs when the server starts and shuts down.

A developer implements a custom service containing a class that implements a particular interface. The administrator configures the custom service in the administrative console, identifying the class created by the developer. When an application server starts, any custom services defined for the application server are loaded and the server run-time calls their initialize methods.

For z/OS, custom services run in servants, not in controllers. For example, because there can be more than one servant started in the life of a server and these servants can be started long after the server (controller) is up, as needed by WLM, a custom service runs during the start of each servant.
