Relationships in ND environments
Relationships can be used in ND (ND) environments without any extra configuration.
In ND (ND) environments, relationships are installed in an application cluster. Relationships are then visible within the cluster, and all servers in the cluster have access to the instance data stored in the relationship database. The ability to run the relationship service in an ND environment makes it scalable and highly available.
The relationship manager allows relationships to be managed across different clusters through a centralized administrative interface.
You connect the relationship manager to a server in a cluster by selecting its relationship MBean.
