Making the Deployment Manager highly available using Sun Cluster requires that you install it on the shared disk. It is also possible to install WebSphere ND locally and only the profile on the shared disk. Nodes are installed on remote machines. We set up an Active/Passive configuration.
After installing the Deployment Manager, create a Deployment Manager resource for Sun Cluster to start, stop, and monitor the Deployment Manager automatically. Then, verify the scenario by failing over and monitoring the nodes and the restart of the Deployment Manager.
The end result should be a Deployment Manager that is available on two Sun systems, as pictured in Figure 13-3.
