Start and stop a node

We can start a node by using the startNode command. You can stop a node by using the stopNode command. Starting and stopping a node is applicable only if your profile, also known as a node, is added to a WAS WAS ND domain or cell.

Before you can start and stop a node, federate the node into a cell.
Start the dmgr and add the node as a managed node of the dmgr. Adding the managed node federates the node.

Start or stop a node as need in administering your WAS ND environment. Before the environment can service requests, have the dmgr and node started, and typically an HTTP server.

Procedure

• Start a node.

  Use one of these methods to start a node:

  • Use the startNode command.

    For example, from a command dialog at the bin directory of the node profile, run the serverStatus -all command. Suppose running the command shows that the node profile is named nodeagent. To start the node, run the following command from a command dialog at the bin directory of the node profile:

    startNode
    

    After starting the node, running the serverStatus -all command shows that the nodeagent status is STARTED.

• Stop a node.

  Use one of these methods to stop a node:

  • Use the stopNode command:

    stopNode
    

    For example, from a command dialog at the bin directory of the node profile, run the serverStatus -all command. Suppose running the command shows that the node profile is named nodeagent. To stop the node, run the following command from a command dialog at the bin directory of the node profile:

    stopNode
    

  • Use the dmgr admin console.

    To use the dmgr admin console to stop a node:

    1. Start the dmgr profile that manages your node.

    2. Start the admin console for the dmgr.
    3. Expand System Administration and click Node Agents.

    4. Select the check box for the node that to stop.

    5. Click Stop.

Results

You have started and stopped a node.

What to do next

We can deploy applications, create a cluster, and generally administer your WAS ND environment.
