Configure Node Manager

Before you begin

Ensure that you have created a machine and that you have installed and configured Node Manager on each physical machine that contains a WebLogic Server instance. For more information on creating a machine, see Create and configure machines. For information on installing and configuring Node Manager, see Node Manager Administrator's Guide.

Node Manager is program that is used to control WebLogic Server instances. A single Node Manager instance is used to control all of the server instances running on the same physical machine. These instances can reside in different clusters, domains, and such. You must configure each machine in your domain to communicate with Node Manager.

For general information on Node Manager, see Node Manager Administrator's Guide.

To configure your machine to communicate with Node Manager:

  1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
  2. In the left pane of the Console, expand Environment and select Machines.
  3. Select the machine for which you want to configure Node Manager.
  4. Select Configuration > Node Manager.
  5. In the Type field, select the Node Manager type from the drop-down list.

    For more information on Node Manager types, see Node Manager Administrator's Guide.

    Note: The values you provide here must correspond to the values you used to configured the Node Manager instance.

  6. In the Listen Address field, enter the DNS name or IP address upon which Node Manager listens.

    If you identify the Listen Address by IP address, you must disable Host Name Verification on Administration Servers that will access Node Manager. For more information and instructions, see Using Host Name Verification in Managing WebLogic Security.

  7. Enter a value in the Listen Port field. This is the port where Node Manager listens for incoming requests.
  8. If you have set the Type field to SSH or RSH, you should specify values in the Node Manager Home and Shell Command fields.

    For more information on configuring Node Manager using SSH or RSH, see Node Manager Administrator's Guide.

  9. Click Save.
  10. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
    Not all changes take effect immediately—some require a restart (see Use the Change Center).
