Peer CRG

A peer cluster resource group (CRG) is a non-switchable cluster resource group in which each IBM® i node in the recovery domain plays an equal role in the recovery of the node. The peer cluster resource group provides peer resiliency for groups of objects or services.

Unlike the other CRG types, in which only the primary CRG node is the node doing the work, in a peer CRG all of the nodes in the recovery domain work together. The purpose of peer CRG is to provide a general distributed-computing framework for which programmers can write applications. The peer cluster resource group provides peer resiliency for groups of objects or services. The end user, end-user applications, and business partner applications, not the system, choose the groups of objects.
