Personal Computers and Workstations
Personal computers (PCs) and workstations can access the PATHMON environment using the RSC
product.
RSC allows client-server computing by supporting a variety of hardware and software configurations
and communications protocols for PCs and workstations. In addition to delegating some processing
normally performed by the NonStop system to the PC, RSC allows you to take advantage of the
graphical user interfaces (GUIs)—pull-down menus, icons, dialog boxes, and online help—that
are available on the PC.
For more information about the RSC product, see the Remote Server Call (RSC) Installation and
Management Guide.
External TCPs
An external TCP is a TCP running outside of your PATHMON environment. The external TCP is
controlled by another PATHMON process, but it can communicate with processes within your
PATHMON environment. The system manager who configures a PATHMON environment determines
how many (if any) external TCPs can communicate with the PATHMON environment.
Remember that the term “external TCP” is relative to your point of view: a TCP that runs in another
PATHMON environment is external to your environment, but it is local to that other environment.
In the other environment, that TCP is exactly like any other local TCP. Information about defining
and managing TCPs is covered in the Pathway/iTS System Management Manual.
