This document describes how to write replicated applications for

|
|
|
|
Berkeley DB 11<span class="emphasis"><em>g</em></span> Release 2 (library version 11.2.5.3). The APIs used to
|
2011-09-13 17:44:24 +00:00
|
|
|
|
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.

This book is aimed at the software engineer responsible for writing a
|
|
|
|
|
|
replicated DB application.

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()</code>
|
|
|
|
|
|
constructor returns an <code class="classname">Environment</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>DB_INSTALL</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.db.DatabaseConfig;
|
|
|
|
|
|
|
|
|
|
|
|
...
|
|
|
|
|
|
|
|
|
|
|
|
// Allow the database to be created.
|
|
|
|
|
|
DatabaseConfig myDbConfig = new DatabaseConfig();
|
|
|
|
|
|
myDbConfig.setAllowCreate(true);</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"><strong class="userinput"><code>import com.sleepycat.db.Database;</code></strong>
|
|
|
|
|
|
import com.sleepycat.db.DatabaseConfig;
|
|
|
|
|
|
|
|
|
|
|
|
...
|
|
|
|
|
|
|
|
|
|
|
|
// Allow the database to be created.
|
|
|
|
|
|
DatabaseConfig myDbConfig = new DatabaseConfig();
|
|
|
|
|
|
myDbConfig.setAllowCreate(true);
|
|
|
|
|
|
<strong class="userinput"><code>Database myDb = new Database("mydb.db", null, myDbConfig);</code></strong> </pre>

<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">

<h3 class="title">Note</h3>

as this.
