RSC/MP Installation and Configuration Guide

Introduction Host Components
2. Network interfaces (NIFs) for the various protocols (nifsock or nifnb) that are
protocol-specific interfaces to the communications facility.
3. Piccolo control program (PIPECP) that provides a command line interface to
control Pipeman.
Host Components
RSC/MP on the NonStop host system has the following components:
RSC/MP Transport (Piccolo) that contains three components:
1. PIPE manager (Pipeman) that maintains the transport connections.
2. Network interfaces (NIFs) for the various platforms (nifsock or nifnb).
3. Piccolo control program (PIPECP) that provides a command line interface to
control Pipeman.
RSC/MP Command interface (RSCCOM) — configures and controls the TDP.
Access Control Server (ACS) — grants or denies workstations the access to
RSC/MP services on the NonStop host. RSC/MP users must design and
implement this optional security feature.
Transaction Delivery Process (TDP) — a persistent NonStop process pair that
delivers and receives messages sent between workstations and the host. Through
the TDP, a workstation can communicate with any Pathway server or named
NonStop process.
LINKMON — the standard communication interface provided by the NonStop host
environment through which the TDP interacts with Pathway servers.
RSC IDS Requester — alternative mechanism provided by RSC/MP for server
access through user-written custom IDS Requesters.
Application Server — the NonStop application server tha t processes transactions,
which can be either a Guardian process or a Pathway server.
