pmnctl is the supported tool for starting and stopping all components in an Oracle instance, with the exception of the Fusion Middleware Control Console. opmnctl provides a centralized way to control and monitor system components from the command line.
If OPMN is configured to discover other Oracle instances, you can use opmnctl to execute control and monitoring commands across multiple Oracle instances simultaneously.
The location of the opmnctl script determines which opmnctl commands you can use.
The opmnctl command exists in two distinct directory location paths:
ORACLE_HOME/opmn/bin/opmnctl: The opmnctl command ORACLE_HOME/opmn/bin/opmnctl location can only be used to create an Oracle instance or a component for an Oracle instance on the local system. opmnctl commands generated from this location cannot be used to manage system processes
ORACLE_INSTANCE/bin/opmnctl: The other opmnctl command which is located in the ORACLE_INSTANCE/bin/ directory location provides a per Oracle instance instantiation of opmnctl. The opmnctl command in this location must be used for managing processes for this Oracle instance and can also be used for creating components for the Oracle instance.
