This book describes how to perform the configuration tasks related to creating an Ensemble production; some of these tasks also apply later when configuring the production for a specific site. This chapter provides some background and an overview of these tasks. It contains the following topics:

Background for System Administrators
This book is intended for both developers and system administrators. If you are a system administrator, this section provides some basic terminology to help you get started.
An Ensemble production is a specialized package of software and documentation that integrates multiple, potentially disparate software systems. A production includes elements that communicate with these external systems, as well as elements that perform processing that is internal to the production.
A production consists of a number of business hosts that communicate with each other (and with external systems). There are three distinct types of business host:
Within a production, all communication is carried out by means of request and response messages between the business hosts.
Ensemble permits only one production to be running in a given namespace at any given time.
A running production continues to run even when you close the Management Portal.
For additional background, see Core Concepts in Monitoring Ensemble.
Introduction to Settings
A major part of configuration is the task of modifying settings. This section provides an introduction.
Settings are configurable values that control the behavior of a production. You can modify these while a production is running and the changes take effect immediately. Settings can affect a production in many ways. For example, a setting can specify:
You can specify settings separately for the production and for each business host.
Some settings, such as Actor Pool Size, Pool Size and Reply Code Actions, should be decided as part of the production design and usually should not be changed later. Other settings are dependent on the environment, such as TCP/IP addresses or file paths. It is appropriate to modify these settings if the environment changes.
Possible Configuration Tasks
While you are creating an Ensemble production, you will need to perform the following tasks:
You might also perform some or all of the following tasks:
If you are a system administrator, you might be most likely to use the chapters Creating and Configuring a Production,” Configuring Business Hosts,”’ and Defining Reusable Items for Use in Settings.”
Accessing the Configuration Options
To configure Ensemble, you use the Management Portal. To access the configuration tools in the Portal:
  1. Click Ensemble.
  2. Click Configure.
Ensemble then displays a menu. The following chapters describe how to use the options on this menu.
Accessing Management Options
Most of this book discusses the Production Configuration page, Ensemble > Configuration > Production. This page includes tabs that provide easy access to management options, which are described elsewhere.
If you click Production Settings above the diagram, the options apply to the entire production. Similarly, if you click a business host, the options apply to that business host.
These management tabs are as follows:
Each these tabs provides a link to a management page (which opens in a new window) with more information. For details on the terminology and tasks, see Managing Ensemble.
On the Jobs tab, you can also select a job and perform one of the following actions on it:
