PCP/RAC --Run a program on a Specific RAC Instance

In 12.1 and later,

Other than the Target Node for a concurrent program,
We can specify the Target Instance on which a praticular program will be running.

To specify a Target Instance,
System Administrator Responsibility > Concurrent > Program > Define > Click 'Session Control' 

==>
If an instance is specified for a program and the instance is up, a manager picks up the request and runs the program on this instance.
ie. though Concurrent Manager is connected to a different instance,  the request will be run on a specific instance.

==>
If no instance is specified, then a manager picks up the request and runs the program on the instance to which the manager is already connected.
