HP NonStop Terminology

Event Management System (EMS)

A subsystem within the NonStop operating system to generate, manage, and monitor events and the log files that these events produce. User-written applications interface with system log files using EMS.

Guardian

An environment that supports interactive or programmatic use with the NonStop operating system.

Guardian Application Execution Facility (GAEF)

An application execution environment built in conjunction with HP NonStop to make use of NonStop products such as Guardian, Pathway, TMF, and NonStop SQL/MP. Use of GAEF enables CA Gen generated applications run efficiently on a NonStop host.

Intelligent Device Support (IDS)

Intelligent Device Support (IDS) is the ability of an application to affect the operation of an application and to obtain data from an intelligent device through a user-written program providing device control. Application programmers can provide set of requester programs that establish an interface between the existing GAEF components and the intelligent devices.

Transaction Management Facility (TMF)

The Transaction Monitoring Facility manages the integrity and consistency of transactions including data recovery on behalf of applications. Normally these transactions involve access to a database.

Pathway

A group of tools (also called Transaction Server/MP, or TS/MP) that provides a transaction processing environment for terminal-based applications. Pathway tools enable development, installation, and management of online transaction processing applications. Pathway/TS is a transaction processing environment for transaction-based applications, using the run-time environment of TS/MP and TM/MP software.

PATHMON

The monitor process of a Pathway system.

Remote Server Call (RSC/MP)

NonStop RSC/MP software lets workstations invoke HP NonStop Transaction Services/MP (formerly TMF) software residing on NonStop servers. RSC/MP improves the performance of applications and maintains the ability to handle high transaction volumes. The HP NonStop platform uses RSC over Piccolo over TCP/IP as its network transport.

Requester

A host-based client in the NonStop Requester/Server model, which is NonStop terminology for the Client/Server model. Requesters are part of Pathway-based applications.

Server

A host-based server in the NonStop Requester/Server model, which is NonStop terminology for the Client/Server model. Servers are part of Pathway-based applications.

Setup Tool

A Pathway–based application that lets users install and deploy CA Gen-generated applications on a NonStop host.

TACL

The command interpreter provided with the NonStop operating system.

Terminal Control Process (TCP)

A terminal control process (TCP) program supplied by HP NonStop that monitors the terminal activity generated by traditional requesters and interprets and executes the screen programs. TCP also controls terminal I/O devices and the server process communication for the transaction processing applications.

Transaction Delivery Process (TDP)

A NonStop Remote Server Call (RSC/MP) process that, in a distributed processing environment, manages transactions between clients and servers.
