Federating middleware nodes

You can use the command line to federate middleware nodes to a WebSphere Virtual Enterprise cell.

 

Before you begin

• Augment a WebSphere Application Server deployment manager profile to use WebSphere Virtual Enterprise. Install the middleware agent on the node.

• Avoid trouble: Each of your middleware nodes must have the same network view for each endpoint and resource that is related to WAS. All host entries or host alias entries that are related to WAS within a hosts file must be included in the hosts file on each of the other middleware nodes in the configuration, including hosts files on nodes that run the middleware agent. For example, if you define a product related host alias called agentA in the hosts file for the nodeA node, then the hosts file on each middleware node must contain an entry for the agentA host alias.gotcha

• Restriction: You cannot federate a middleware node into a deployment manager that is running on the z/OS operating system.

 

About this task

Federate a middleware node if it was not federated into the cell during the middleware agent installation. You can perform this task by using a command line or the administrative console.

 

Procedure

To federate the node from the command line, log on to the middleware node computer and run..

agent_install_root/bin/addAgent.sh -host dmgr_host -port dmgr_port -user admin_id -password admin_passwd

For example, the following example federates the node to the fooblade01 deployment manager computer:

addAgent.sh -host fooblade01 -port 9060 -user admin -password admin

To start the agent using the commandline...

agent_install_root/bin/StartAgent.sh

To start the agent from the administrative console:

System administration | Middleware nodes | Select operational action menu | Start agent | Run

 

Results

The middleware node is displayed as an unmanaged node in WebSphere XD cell. If you encounter problems in federating and adding nodes, check the following log files:

• install_root/logs/addAgent.log
• install_root/logs/middlewareagent/SystemOut.log
• install_root/logs/middlewareagent/SystemErr.log
