Workstation Components
Workstation Components
The workstation components are:
•
RSC/MP I/O Manager (RSCPIPE) — Matches I/O replies with requests, notifies
applications of I/O completion, maps shared connections to a single host
connection, and so on.
•
RSC/MP Transport Pipe Manager (Pipeman) — Maintains the transport
connections (using Piccolo), freeing the RSC/MP layers for other functions. You
configure Pipeman using the PIPE.INI file.
•
Network interfaces (NIFs) — Manages the protocol-specific interface to the
communications facility. Each Pipeman process can have one or more NIF
processes.
•
Piccolo control program (PIPECP) — A command line interface used to control
Pipeman.
The NonStop Host
The NonStop host provides these services for online transaction processing:
•
Distributed system architecture
•
Parallel processing
•
Fault tolerance
•
Networking and connectivity facilities
•
Expandability
•
Data integrity
•
Transaction management
You can run multiple copies of the RSC/MP host software on different CPUs, taking
advantage of parallel processing on the NonStop system. RSC/MP on a NonStop host
provides persistent operation by running as a fault-tolerant process pair.
Through RSC/MP you can use the data integrity and management capabilities of TMF.
However, the TMF product cannot protect data stored on the workstation.
RSC/MP also allows you to take advantage of all the benefits the Pathway/TS online
transaction processing environment provides; for example, server classes and server
process management, load balancing, and server process restart after failure.
