Process agent is an agent that starts, terminates or monitors the process designated by a user.
Process means that an application achieves a single process.
The execution binary should have the same name as the process residing in the memory.
The execution binary program should be installed in the same directory on every node. It cannot be installed in the data areas such as mirror disks or shared disks.
