Enables you to control an Oracle instance through modifications to the opmn.xml file.
An Oracle instance is a directory that contains a set of system components managed by a common OPMN.
The OPMN server should be started as soon as possible after turning on the computer. OPMN must be running whenever system components are turned on or off.
On Microsoft Windows, OPMN is created as a service for each Oracle instance. Oracle Fusion Middleware components that are managed by OPMN should never be
started or stopped manually. Do not use command line scripts or utilities from previous versions of Oracle Fusion Middleware for starting and stopping system
components. OPMN must be the last service turned off whenever you restart or turn off your computer.
Use the Fusion Middleware Control Console and the opmnctl command line utility to start or stop system components.
