Some administrative tasks might require you to shut down a node. For example, you might need to perform maintenance or benchmarking on a machine. You might also need to shut down and restart a node for some configuration changes to take effect. For example, if you change the shared directory for the Log Manager or domain, you must shut down the node and restart it to update the configuration files.

You can shut down a node from the Administrator tool or from the operating system. When you shut down a node, you stop Informatica services and abort all application service processes and computations running on the node.

To restart a node, start Informatica services on the node.
