Introduction

For a general introduction to Reliable Transaction Router, Version 3.2 (RTR), you should read the introductory chapter in the Reliable Transaction Router Application Design Guide. Additional information about the Reliable Transaction Router is available in the Reliable Transaction Router Application Programmer's Reference Manual.

In order to use RTR, you must install the RTR software and your application. See the Reliable Transaction Router Installation Guide for instructions for installing RTR.

1.1 Getting Started

RTR applications use the API calls described in the Reliable Transaction Router Application Programmer's Reference Manual. Before an RTR application can be used, RTR must be started on every node in your RTR network. You do this is by issuing a START RTR command on each node. You may wish to include the START RTR command in a startup command procedure for each node, so that RTR is started whenever a node is booted.

Many applications can use RTR at the same time without interfering with one another. This is achieved by defining a separate facility for each application. A facility can be thought of as an application's own runtime environment of RTR. (In addition, distributed RTR applications may start and execute many transactions. RTR is capable of massively parallel operation.)

Before application processes are started, a facility must be defined using the CREATE FACILITY command. You may wish to include the CREATE FACILITY command to the command procedure used to start the application.

The rest of this chapter explains how to use RTR commands. The START RTR and CREATE FACILITY commands are described in detail in Chapter 2 and Chapter 6.

1.2 Entering Commands

RTR is started, configured and maintained by using the RTR Command Line Interface (CLI). The RTR CLI is used to start, set up and monitor the operation of RTR.

The RTR CLI is accessed by entering RTR at the operating system prompt. Commands can either be entered on the same line as the RTR verb, for example:

% rtr command
