On each node where you install Informatica, the installer creates a Windows service or UNIX daemon to run Informatica. When the installation completes successfully, the installer starts the Informatica service on Windows or the Informatica daemon on UNIX.
The Informatica service runs the Service Manager on the node. The Service Manager manages all domain functions and starts application services configured to run on the node. The method you use to start or stop Informatica depends on the operating system. You can use Informatica Administrator to shut down a node. When you shut down a node, you stop Informatica on the node.
You can configure the behavior of the Informatica Windows service.
The Informatica service also runs Informatica Administrator. You use Informatica Administrator to administer the Informatica domain objects and user accounts. Log in to Informatica Administrator to create the user accounts for users of Informatica and to create and configure the application services in the domain.
