This document describes how to write replicated Berkeley DB, Java Edition
applications. The APIs used to implement replication in your
application are described here. This book describes the concepts
surrounding replication, the scenarios under which you might choose
to use it, and the architectural requirements that a replication
application has over a transactional application.
</p>
<p>
This book is aimed at the software engineer responsible for writing a
replicated JE application.
</p>
<p>
This book assumes that you have already read and understood the
concepts contained in the <em class="citetitle">Berkeley DB, Java Edition Getting Started with Transaction Processing</em> guide.

The following typographical conventions are used within in this manual:
</p>
<p>
Class names are represented in <code class="classname">monospaced font</code>, as are <code class="methodname">method
names</code>. For example:
"The <code class="methodname">Environment()</code>
constructor returns an <code class="classname">Environment</code> class object."
</p>
<p>
Variable or non-literal text is presented in <span class="emphasis"><em>italics</em></span>. For example: "Go to your
<span class="emphasis"><em>JE_HOME</em></span> directory."
</p>
<p>
Program examples are displayed in a <code class="classname">monospaced font</code> on a shaded background.
For example:
</p>
<pre class="programlisting">import com.sleepycat.je.Environment;
...
// Open the environment. Allow it to be created if it does not already
// exist.
Environment myDbEnv;</pre>
<p>
In some situations, programming examples are updated from one chapter to the next. When
this occurs, the new code is presented in <strong class="userinput"><code>monospaced bold</code></strong> font. For example:
</p>
<pre class="programlisting">import com.sleepycat.je.Environment;
<strong class="userinput"><code>import com.sleepycat.je.EnvironmentConfig;
import java.io.File;</code></strong>
...
// Open the environment. Allow it to be created if it does not already
// exist.
Environment myDbEnv;
<strong class="userinput"><code>EnvironmentConfig envConfig = new EnvironmentConfig();
envConfig.setAllowCreate(true);
myDbEnv = new Environment(new File("/export/dbEnv"), envConfig);</code></strong> </pre>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p>
Finally, notes of special interest are represented using a note block such
as this.
