5.1.2 Overview of using JP1/Base in a cluster system
To operate JP1/Base in a logical host environment, you must provide a logical IP address and a shared disk for storing data necessary for failovers. You must also register JP1/Base with the clustering software so that the software can control the start and stop of JP1/Base and monitor the operations of JP1/Base. Setting up a logical host results in settings that specify which servers store necessary data on the shared disk and use a logical IP address for communication. When running in a logical host environment, JP1/Base uses data stored on the shared disk so that the secondary server can take over processing from the primary server if the primary server fails.
The following sections describe prerequisites for using JP1/Base in a cluster system, and explain how to set up an environment as such.
