Define and Add Nodes
To create a node, you define the node as a gateway or worker node and then add the node to the domain.
Use either of the following programs to define a node:
- Informatica installer
- Run the installer on each machine you want to define as a node.
- infasetup command line program
- Run the infasetup DefineGatewayNode or infasetup DefineWorkerNode command on each machine that you want to define as a node. You might use infasetup to define a node if you decide to move a node from one domain to another domain.
When the Informatica installer or infasetup defines a node, the program creates nodemeta.xml. This file is the node configuration file for the node. A gateway node uses information in nodemeta.xml to connect to the domain configuration database. A worker node uses the information in nodemeta.xml to connect to the domain. The file is stored in the following directory on each node:
<Informatica installation directory>/isp/config
When you define a node using the Informatica installer, the installer adds the node to the domain with both the service and compute roles enabled. When you log in to the Administrator tool, the node appears in the Navigator.
When you define a node with infasetup, you must manually add the node to the domain. You can add a node to the domain in the Administrator tool or with the infacmd isp AddDomainNode command. When you add the node, you specify the roles to enable on the node.
You can use the Administrator tool to add a node to the domain before you define the node. In this case, the Administrator tool displays a message saying that you need to run the Informatica installer to associate the node with a physical host name and port number. The name that you enter for the node must be the same name that you use when you define the node.
Adding Nodes to the Domain
You can use the Administrator tool to add a node to the domain.
Use the Administrator tool to add a node to the domain in the following situations:
- •After you run the infasetup DefineGatewayNode or infasetup DefineWorkerNode command.
- •When you decide to add the node before running the Informatica installer or infasetup command line program to define the node.
1. In the Administrator tool, click the Manage tab > Services and Nodes view.
2. In the Domain Navigator, select the folder where you want to add the node. If you do not want the node to appear in a folder, select the domain.
3. On the Navigator Actions menu, click New > Node.
The Create Node dialog box appears.
4. Enter the node name.
The name must be the same node name that you use when you define the node.
5. If you want to change the folder for the node, click Browse and choose a new folder or the domain.
6. Optionally update the node role.
By default, each node has both the service and compute roles. If a node is assigned to a Data Integration Service grid, you might want to update the node role to dedicate the node to running the Data Integration Service process or to running mappings.
7. Click OK.
If you add a node to the domain before you define the node using the Informatica installer or infasetup, the Administrator tool displays a message saying that you need to run the installer to associate the node with a physical host name and port number.
