TCP/IP (Parallel Library) Migration Guide

HP NonStop TCP/IP (Parallel Library) Migration Guide—522272-003

About This Guide

This guide is intended for network and system administrators, application

programmers, and IT professionals seeking an overview of the migration

considerations for Parallel Library TCP/IP. Network and system administrators who are

going to configure the Parallel Library TCP/IP environment and application

programmers who plan to use Parallel Library TCP/IP should use this guide to find out

about any migration issues that affect your configuration or applications. HP

recommends that you refer this guide with the TCP/IP (Parallel Library) Configuration

and Management Manual.

This guide provides information about migrating conventional TCP/IP applications to

the Parallel Library TCP/IP environment including current restrictions of Parallel Library

TCP/IP, management considerations, configuration comparisons between conventional

TCP/IP and Parallel Library TCP/IP, and user programming issues.

This guide assumes that you have a working knowledge of industry-standard TCP/IP,

and are familiar with HP NonStop™ S-series system architecture, HP NonStop TCP/IP,

and the ServerNet LAN systems access (SLSA) subsystem. The following section lists

the HP manuals and other books that are related to Parallel Library TCP/IP.

In this guide, the NonStop TCP/IP product is referred to as “conventional TCP/IP” for

easy comparison to Parallel Library TCP/IP.
