16.3.1 Procedure for setting up the node switching system for the host management model

The following figure shows the procedure for setting up the node switching system for the host management model:

Figure 16‒3: Procedure for setting up the node switching system for the host management model

The points 1 to 6 in the figure are described as follows:

1. Create a partition in the shared disk, and then build the file system.

   When using a global transaction, create the storage location for the transaction information. Note that this step is not required when using the local transaction, if the HA monitor is used.

2. Allocate a shared disk to the system.

   When allocating a shared disk to the system, check that you allocate the same drive character in the virtual host 1 of the active node 1 and the virtual host 1 of the standby node, and the virtual host 2 of the active node 2 and the virtual host 2 of the standby node.

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

   Set up the cluster server environment (each logical server and the hosts on which the logical servers are set up) in the Easy Setup definition file of the Smart Composer functionality of Management Server. For details, see 16.3.2 Cluster server environment settings.

4. Edit the setup file.

   Set up various definition files used on the Administration Agent and Management Server. For details, see 16.3.3 Editing the setup file.

5. Set up the cluster.

   Create the cluster software environment settings and the script files for monitoring the Management Sever and Administration Agent. For details, see 16.3.4 Cluster settings.

6. Set up Application Server.

   The J2EE application deploys Application Server in a cluster configuration and sets up the resource adapter. For details, see 16.3.5 Application Server settings.

Implement the above procedure for both, active node and standby node.

Reference note

The logical servers are deployed on different hosts, but externally operate as the same logical server. On the other hand, Management Servers operate separately on different hosts and have respective management domains. Define one virtual host in one management domain and set up as active node Application Server host and standby node Application Server host respectively. A virtual host controls the starting and stopping of Application Server using the Administration Agent, but allocates the same IP address as the one used for operations and is defined so that it appears to be the same host.
