2.3.9 Adding the Node Managers

If you have Node Managers being used in the environment, each Node Manager has to be defined in the topology file.

1. Click anywhere in the workspace in the Topology tab.
   Ensure that the existing topology objects in the workspace are not selected.
2. Select Edit > Add New Node Manager to add a Node Manager to the workspace.
   Alternatively, you can select the Add New Item tool on the toolbar, select Add New Node Manager in the dialog box, and click OK.
   A Node Manager (nm1) is created in the workspace.
3. Select the Node Manager object you just created, and define the following attributes for the Node Manager:

   Attribute	Description
   ID	Keep the default value, nm1. The ID attribute is an identifier that is used to refer to this Node Manager from other parts of the topology.
   Name	Enter the name of the Node Manager. This attribute should match the name provided during domain configuration. For example, Machine 1.
   Credential	This attribute is used to identify the credential in the wallet file that will be used to connect to the Node Manager. Click select to select the credential for the Node Manager from the wallet file you loaded in Loading a Wallet File. When you click select, a dialog box appears that lists the credentials in the given wallet. If the credential already exists in the wallet, select the appropriate credential from the list and click OK. If the credential does not exist in the wallet, click New to add the Node Manager credential to the wallet and to provide an alias for this credential.
   NmAddress	Under Tuning Parameter Settings, click the Add New Item icon to add a value for the Node Manager listen address (NmAddress) attribute. When you click this icon, a dialog box appears. For Name, select NmAddress from the drop-down menu, and then enter the Node Manager listen address in the Value field.
   NmPort	Under Tuning Parameter Settings, click the Add New Item icon to add a value for the Node Manager listen port (NmPort) attribute. When you click this icon, a dialog box appears. For Name, select NmPort from the drop-down menu, and then enter the Node Manager listen port in the Value field (for example, 5556).

4. Repeat this process to add and define a second Node Manager, nm2.

After you have added and defined the Node Managers, your workspace should look similar to the following example:
