17.3.1 Example system configuration for a 1-to-1 node switching system

The following figure shows an example of system configuration for operating Management Server in the 1-to-1 node switching system by linking with cluster software:

• To operate the Management Server in the 1-to-1 node switching system

  The following figure shows the example of system configuration for operating the Management Server in the 1-to-1 node switching system. The Management Server appears to restart with the same logical address from the Web server and from the Application Server during node switching.

  Reference note

  In the Management Server, the Management Server-related settings such as the configuration information about the management domain are stored in a file. In the 1-to-1 node switching system of the Management Server, if there are changes in the management domain configuration, the information defined in the executing node (such as various definition files of the Management Server, and the J2EE applications and the resource adapters defined in the Management Server) must be copied into the standby node before starting the system so that the executing node information is inherited in the standby node. For details on how to copy the Management Server-related settings, see 17.5.4 Copying the Management Server settings from the active node to the spare node.

You can execute the following types of operations in the 1-to-1 node switching system:

For JP1 integration:

In a cluster software configuration, you can integrate the system with JP1.

For integrating the system with JP1, the Application Server also requires JP1/Base. You must manage JP1 in the cluster software separately from the Application Server.

Integration with cluster software in a database server:

You can also use a cluster software configuration in the database server. In this case, if only the virtual address (logical address) is recognized in the Application Server, you cannot recognize that the database server is using the cluster software.

Application of the load balancer

Though not described in this system configuration example, you can also apply the load balancer by preparing several Web servers in the same configuration. As a result, you can improve the reliability and operating rate of the Web server.

For details on the system configuration to be used for operating Application Server in the 1-to-1 node switching system, see 3.11.1 Configuration in which executing node and standby node of Application Server are in 1-to-1 ratio (when transaction service is not used) and 3.11.2 Configuration in which executing node and standby node of Application Server are in 1-to-1 ratio (when using transaction service) in the uCosminexus Application Server System Design Guide. For details on the system configuration to be used for operating Management Server in the 1-to-1 node switching system, see 3.11.3 Configuration in which executing node and standby node of Management Server are in 1-to-1 ratio in the uCosminexus Application Server System Design Guide.
