What is a Cluster Agent?
A Cluster agent is a k-sh script, a C-program, or a binary that manages the availability of an application. The agent starts, stops, monitors the health of the application, and takes corrective action to regain application availability upon failure. Applications need not be modified to benefit from the enhanced availability offered by the Cluster agent. If your application does not have an agent already made for it, you can create your own using the Cluster Agent Builder (included with the Cluster software). This agent builder has an easy to use, “wizard” graphical user interface which leads the user step by step through the process of creating an agent. After the user completes the agent builder process, a ready-to-use agent is created (the whole process takes only a few minutes from start to finish).
