17.7.1 Procedure for setting the 1-to-1 node switching system in the Management Server

This subsection describes the example system configuration and the procedure for specifying the system settings.

Organization of this subsection

(1) System configuration example

The following figure shows the example configuration for the 1-to-1 node switching system of the Management Server. Note that the subsequent points describe the example system configuration using this example configuration.

Figure 17‒11: Configuration example of 1-to-1 node switching system for the Management Server (In UNIX)

[Figure]

The executing node of the management server (active node) and the standby node of the management server (spare node) are deployed as 1-to-1.

In the 1-to-1 node switching system of the Management Server, first the cluster is built, and then the management server is defined as the active node and the spare node in the cluster. Also, specify the server identification name (alias name of the server) for the used commands, and the messages output to the HA monitor. Specify the same name in the active node and the spare node (such as CMS in the example).

Note that in order to deploy the Application Server in a cluster configuration, set up the alias IP address and specify the 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. When there is a 1-to-1 node switching system, the alias IP address is dynamically allocated by the HA monitor.

(2) Procedure of the system setup

For integrating the system with the HA monitor, settings must be specified for the Management Server and the HA monitor file. The following figure shows the procedure for setting up the 1-to-1 node switching system of the Management Server:

Stages 1. to 9. of the figure are explained below:

  1. When using the global transaction, create a partition in the shared disk and build the file system.

    To use the global transaction, create the location to store the transaction information.

  2. When using the global transaction, allocate a shared disk to the system.

    When allocating a shared disk to the system, specify the same directory to mount the shared disk in the active node and the spare node.

  3. Set up the cluster server environment in the Management Server.

    In the Easy Setup definition file of the Smart Composer functionality for the Management Server, you specify the settings for using the HA monitor. For details, see 17.7.2 Environment settings in the cluster server.

  4. Edit the setup files.

    Specify the settings for various definition files of the Management Server that cannot be specified in the Easy Setup definition file. For details, see 17.7.3 Editing the setup files.

  5. Copy the Management Server settings from the active node to the spare node.

    To set the same environment for the active node and the spare node, copy the Management Server-related settings of the active node into the spare node. For details, see 17.7.4 Copying the Management Server settings from the active node to the spare node.

  6. Set up the HA monitor environment.

    Define the HA monitor environment in the sysdef file of the HA monitor. For details, see 17.7.5 HA monitor environment settings.

  7. Create the shell script file.

    Create the shell script file to monitor the Management Server and to start and stop the Management Server. For details, see 17.7.6 Creating the shell script file.

  8. Set up a server-compliant environment.

    Define the environment for the active node server and spare node server to be operated on the node, in the servers file of the HA monitor. For details, see 17.7.7 Server-compliant environment settings.

  9. Set up the LAN status.

    In the LAN status setup files of the HA monitor, specify settings such as the IP address of the LAN adapter to define the switching of LAN in the HA monitor. For details, see 17.7.8 LAN status setup.
