Example: A cluster administrative domain to manage peer resources

Provides an example configuration of a cluster administrative domain used to monitor resources within a cluster.

This example configuration provides the following:

Two-node cluster
A cluster administrative domain with the two nodes in its domain node list
A Monitored Resource Entry (MRE) for a user profile which is to be synchronized within the domain.

A two-node cluster featuring an application CRG and a data CRG.

Start of change In this example, the administrator wants to ensure the user profile remains consistent throughout the cluster so a cluster administrative domain was created to monitor and synchronize changes to the user profile. The cluster administrative domain is represented by a peer CRG that contains Node L and Node R. A monitored resource entry is added to the cluster administrative domain for the user profile. In this example, all of the attributes of the user profile were specified when the MRE was added. Therefore when any attribute of the user profile is changed on either node L or node R, the change is automatically propagated to the active nodes in the domain, once the CRG is started. End of change

The following steps describe what the administrator completed to set up this example:

Create a cluster with Nodes L and R.
Create a cluster administrative domain on Nodes L and R
Add an MRE to represent the user profile
Start the Peer CRG that represents the cluster administrative domain
Change the user profile on either node L or on node R. The user profile on the other node will be changed automatically by the cluster administrative domain. The global status for the monitored resource will be consistent if the change is successful.
