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>
|
|
|
|
|
|
Structure names are represented in <code class="classname">monospaced font</code>, as are <code class="methodname">method
|
|
|
|
|
|
names</code>. For example: "<code class="methodname">DB->open()</code> is a method
|
|
|
|
|
|
on a <code class="classname">DB</code> 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 <code class="classname">monospaced font</code> 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
|
|
|
|
|

|
|
|
|
|
|
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 <strong class="userinput"><code>monospaced bold</code></strong> 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 */
|
|
|
|
|
|
<strong class="userinput"><code>DB *itemname_sdbp; /* Index based on the item name index */</code></strong>
|
|
|
|
|
|
char *db_home_dir; /* Directory containing the database
|
|
|
|
|
|
* files */
|
|
|
|
|
|
<strong class="userinput"><code>char *itemname_db_name; /* Itemname secondary database */</code></strong>
