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
