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.
