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