OPMN is installed and configured with every Oracle Application Server installation type and is essential for running Oracle Application Server.
OPMN features the following functionality:
• Provides a command-line interface for process control and monitoring for single or multiple Oracle Application Server components and instances.
• Provides an integrated way to manage Oracle Application Server components.
• Enables management of Oracle Application Server subcomponents and sub-subcomponents.
• Channels all events from different Oracle Application Server component instances to all Oracle Application Server components that can utilize them.
• Solves interdependency issues between Oracle Application Server components by enabling you to start and stop components in order.
• Enables customizing of enterprise functionality by using event scripts.
• Enables gathering of host and Oracle Application Server process statistics and tasks.
• Provides automatic restart of Oracle Application Server processes when they become unresponsive, terminate unexpectedly, or become unreachable as determined by ping and notification operations.
• Provides automatic death detection of Oracle Application Server processes.
• Does not depend on any other Oracle Application Server component being up and running before it can be started and used.
• The OPMN server should be started as soon as possible after turning on the host. OPMN must be running whenever OPMN-managed components are turned on or off.

Using Command Prompt:
In the command prompt navigate to \instances\instance_number\bin\ (e.g. C:\OBI\instances\instance2\bin\), then execute the following commands as per your requirement.
- To Start all OPMN processes: opmnctl startall
- To Stop all OPMN processes: opmnctl stopall
- To see the status of all system components: opmnctl status
startproc, stopproc, restartproc are the commands to start or stop individual processes. Here is the example to start all 5 System components individually.
- BI Cluster Control: opmnctl startproc ias-component=coreapplication_obiccs1
- BI Scheduler: opmnctl startproc ias-component=coreapplication_obisch1
- BI Java Host: opmnctl startproc ias-component=coreapplication_obijh1
- BI Presentation Services: opmnctl startproc ias-component=coreapplication_obips1
- BI Server: opmnctl startproc ias-component=coreapplication_obis1
