This document describes how to use transactions with your Berkeley DB, Java Edition
applications. It is intended to describe how to
transaction protect your application's data. The APIs used to perform this task
are described here, as are the environment infrastructure and administrative tasks
required by a transactional application. This book also
describes multi-threaded JE applications and the requirements they
have for deadlock detection.
</p>
<p>
This book describes Berkeley DB, Java Edition version 12<span class="emphasis"><em>c</em></span> Release 2
</p>
<p>
This book is aimed at the software engineer responsible for writing a
transactional JE application.
</p>
<p>
This book assumes that you have already read and understood the
concepts contained in the
<span><em class="citetitle">Getting Started with Berkeley DB, Java Edition</em> guide.</span>

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:
<span>"The <code class="methodname">Environment.openDatabase()</code> method
returns a <code class="classname">Database</code> class object."</span>
</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.
