The dmctl command is a command line tool for interacting with a Manager. It may be used to create instances of new classes or manually populate attributes in a Manager. It can either execute commands typed at the command line, execute commands read from a batch file, or interactively read commands that the you type.
If the Global Manager is already running, and you use dmctl to modify class properties that it subscribes to, you need to re-synchronize the topology. “Synchronizing topology changes with the Global Manager” on page 96 provides additional information.
