This subsection describes the example of the system configuration and the procedures for specifying the system settings when integrating with Windows Server Failover Cluster.
The following figure shows an example configuration of a mutual node switching system. Note that the subsequent points describe the system configuration based on this configuration example.
Figure 18-5 Configuration example of mutual node switching system (in Windows)
In this example, two types of application servers (assumed to be application server 1 and application server 2) are used. The executing node (active node 1) and standby node (spare node 2) of Application Server 1 and the executing node (active node 2) and standby node (spare node 1) of Application Server 2 are deployed in 1-to-1 ratio. Each Application Server deploys a Management Server having a separate management domain, and the Management Server is started on both the machines.
In the mutual node switching system, two virtual hosts are defined in one management domain and are configured as the host of the active node Application Server and the host of the spare node Application Server respectively. In this example, the combination is as follows:
The virtual host controls the starting and stopping of Application Server using one Administration Agent, but the IP addresses allocated for operations are different, so the virtual hosts are defined as apparently different hosts.
Note that in order to deploy Application Server in a cluster configuration, set the alias IP address and specify settings in such a way so that the running node inherits the alias IP address, and the client does not realize the nodes in the cluster. For the mutual node switching system, the alias IP address is the address (cluster IP address) that is dynamically allocated by the cluster software. For the IP address to be used in the operations of Application Server, you use the cluster IP address, and for sending the requests from the Management Server to the Administration Agent, you use the IP address (stationary IP address) that does not move to other nodes due to node switching.
When integrating the system with Windows Server Failover Cluster, you must set up Management Server and Cluster Administrator. The following figure shows the procedure for setting up the mutual node switching system:
