Assure MIMIX for PowerHA provides the construct to enhance the ability to group and control resources in a way that maintains relationships between resources when responding to cluster events. In MIMIX, this is called an application group.
An application group identifies an application, including the application name, release level, its IP takeover address, an exit program to control the various actions, and the data associated with the application. An application group also includes the node entries that define the recovery domain for the application.
The most significant benefit of application groups is that they provide the ability to control switching of all data replication associated with an application in a single switch request. When a cluster event occurs, the application group provides a coordinated response for all of its associated resources. Application groups also integrate and simplify cluster management and data replication management.
Application groups can also be used when there is no application, only data that needs to be resilient.
