Websphere : Federation of the WAS nodes

By federating nodes to the deployment manager we can administer all the application servers through one deployment manager console.

1. You can add a new node through the admin console (explained below) &
   
2. Using addNode command at command prompt

TO FEDERATE:

Log on to the admin console of the application server Go to servers -> Application Servers -> server -> ports And note the soap connector address (here 8880).

Communications between the node agent and deployment manager takes place through this port.

Log on to the WAS admin:

JUST FOR your information to check what is present in the cell, Go to admin console -> cell -> Local Topology

In the cell you will note that only dmgr is part of the cell as of now

[Before federation]

System administration -> nodes -> add node -> managed node

Check the message whether the node is successfully federated.

Now go to the appserver profile root/logs

And check the log file addNode.txt

See the message which the node federated successfully.

Go to application server profile root/logs/nodeagent/logs

And check for systemOut.log and the message.

The configuration synchronization completed successfully.

To verify federation from the admin console:

System administration -> nodes -> check the node whether it is synchronized.

Start the application server.

Check the applications if they are running.

Go to node agents; Verify that a node agent process is created on the node you federated.

Now you can see the node added.

Note: Till now we have seen federating a node from deployment manager’s admin console. We can also federate a node from the command prompt of application server’s command prompt.
