Reconfiguring application controllers
An application controller is a cluster resource used to control an application that must be kept highly available. It includes start and stop scripts.
Note that this section does not discuss how to write the start and stop scripts. See the vendor documentation for specific product information on starting and stopping a particular application.
If you intend to add an application controller dynamically, it is very important to test the server scripts beforehand, as they will take effect during the dynamic reconfiguration operation.
