16.3.5 Application Server settings

To set up Application Server, invoke the Administration Agent and Management Server of the active node and standby node respectively. After invocation, set up the logical server, deploy the setup file, and then import the applications and resource adapters into the J2EE server. The procedure to set up Application Server for 2 active nodes (Node1, Node2) and 1 standby node (Node3) is as follows:

1. For Node1and Node2, the cluster software starts the node.

   The operating state is normal with the active node Application Server (virtual host 1 of Node1 and virtual host 2 of Node2) in running state and the standby node Application Server (virtual host 1 and virtual host 2 of Node3) in standby state.

   

2. Based on the Easy Setup definition file that is setup, the Web system is set up and started using the Smart Composer functionality commands for the active node Application Server (virtual host 1 of Node1and virtual host 2 of Node2). Also, the server management commands are used to import the J2EE applications and resource adapters, and then the imported J2EE applications and resource adapters are started.

   For details about operations via server management commands, see 3. Basic Operations of Server Management Commands in the uCosminexus Application Server Application Setup Guide.

3. The cluster software switches the node of virtual host 1.

   The nodes of active node Application Server (virtual host 1 of Node1) are switched and the standby node Application Server (virtual host 1 of Node3) is started.

   

4. Implement step 2. for the standby node Application Server (virtual host 1 of Node3).

5. The cluster software returns the node of virtual host 1.

   The nodes of the standby node Application Server (virtual host 1 of Node3) are switched and the active node Application Server (virtual host 1 of Node1) is started. The system returns to a normal operating state.

   

6. The cluster software switches the node of virtual host 2.

   The nodes of the active node Application Server (virtual host 2 of Node2) are switched and the standby node Application Server (virtual host 2 of Node3) is started.

   

7. Implement step 2 for the standby node Application Server (virtual host 2 of Node3).

8. The cluster software returns the node of virtual host 2.

   Nodes of the standby node Application Server (virtual host 2 of Node3) are switched and the active node Application Server (virtual host 2 of Node2) is started. The system returns to a normal operating state.

   

9. In Node1 and Node2, the cluster software stops the node.

   The active node Application Server (virtual host 1 of Node1and virtual host 2 of Node2) stops and is in a waiting state.
