This document describes how to write replicated Berkeley DB 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 DB application.
</p>
<p>
This book assumes that you have already read and understood the
concepts contained in the
<span><i class="citetitle">Berkeley DB Getting Started with Transaction Processing</i> guide.</span>

<p>
The following typographical conventions are used within in this manual:
</p>
<p>
Structure names are represented in <tt class="classname">monospaced font</tt>, as are <tt class="methodname">method
names</tt>. For example: "<tt class="methodname">DB->open()</tt> is a method
on a <tt class="classname">DB</tt> handle."
</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 <tt class="classname">monospaced font</tt> on a shaded background.
For example:
</p>
<pre class="programlisting">/* File: gettingstarted_common.h */
typedef struct stock_dbs {
DB *inventory_dbp; /* Database containing inventory information */
DB *vendor_dbp; /* Database containing vendor information */
char *db_home_dir; /* Directory containing the database files */
char *inventory_db_name; /* Name of the inventory database */
char *vendor_db_name; /* Name of the vendor database */
} STOCK_DBS; </pre>
<p>
In some situations, programming examples are updated from one chapter to the next. When
this occurs, the new code is presented in <b class="userinput"><tt>monospaced bold</tt></b> font. For example:
</p>
<pre class="programlisting">typedef struct stock_dbs {
DB *inventory_dbp; /* Database containing inventory information */
DB *vendor_dbp; /* Database containing vendor information */
<b class="userinput"><tt>DB *itemname_sdbp; /* Index based on the item name index */</tt></b>
char *db_home_dir; /* Directory containing the database files */
<b class="userinput"><tt>char *itemname_db_name; /* Itemname secondary database */</tt></b>
char *inventory_db_name; /* Name of the inventory database */
char *vendor_db_name; /* Name of the vendor database */
} STOCK_DBS; </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.

<h3 class="title"><a id="moreinfo"></a>For More Information</h3>
