Data CRG

A data cluster resource group (CRG) is an IBM® i system object which assists in data replication between the primary and backup nodes in the recovery domain. A data CRG does not do the replication, but uses the exit program to inform a replication program when to start or end replication, and on which nodes to replicate. A data CRG does not monitor for a data resource failure.

Data CRGs are primarily used with logical replication applications, which are provided by several high availability IBM Business Partners.
