This subsection describes an example of the system configuration and the procedure for setting up systems, when the systems are integrated with Windows Server Failover Cluster.
The following figure shows an example of system configuration of the N-to-1 recovery system. Note that the subsequent sections describe examples of building the system using this example of system configuration.
Figure 19-3 Example of system configuration (In the N-to-1 recovery system)
In this example, deploy four executing node servers and one recovery server. In three of the four executing nodes, deploy the same J2EE server called MyServer in which you deploy the same J2EE application and resource adapter. In the remaining one executing node, deploy a J2EE server called MyServer2 that is different from the other J2EE server names and has a different J2EE application and resource adapter deployed in it.
In the N-to-1 recovery configuration, build multiple virtual hosts within one cluster. A combination of the executing node and recovery node configures the virtual host with the J2EE server deployed in a cluster configuration. In the N-to-1 recovery configuration, the J2EE server operates within the virtual host rather than the cluster. Therefore, set the IP address and host name of the virtual host.
A virtual host is defined as a resource group and includes the 'physical disk resource', 'IP address resource', 'network resource name', and 'general-purpose script resource'. The following figure shows an example of the resource groups described in this section:
Figure 19-4 Example of the resource group
To deploy Application Server in a cluster configuration, set the alias IP address, and specify settings so that the running node inherits the alias IP address and the client does not consider the nodes in the cluster. In the N-to-1 recovery configuration, the alias IP address becomes the IP address of the virtual host.
In the J2EE server of the standby node, import and deploy a resource adapter with the same settings as all resource adapters that you are using in the J2EE servers of the executing node.
When integrating with Windows Server Failover Cluster, you must set up the management portal and cluster administrator. The following figure shows the procedure for setting the N-to-1 recovery system:
