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

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.
