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> <div class="sect1" lang="en" xml:lang="en"> <div class="titlepage"> <div> <div> <h2 class="title" style="clear: both"><a id="conventions"></a>Conventions Used in this Book</h2> </div> </div> <div></div> </div> <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. </p> </div> <div class="sect2" lang="en" xml:lang="en"> <div class="titlepage"> <div> <div> <h3 class="title"><a id="moreinfo"></a>For More Information</h3> </div> </div> <div></div> </div> <p> Beyond this manual, you may also find the following sources of information useful when building a transactional DB application: </p> <div class="itemizedlist"> <ul type="disc"> <li> <p> <a href="http://www.oracle.com/technology/documentation/berkeley-db/db/gsg_txn/C/index.html" target="_top"> Getting Started with Transaction Processing for C </a> </p> </li> <li> <p> <a href="http://www.oracle.com/technology/documentation/berkeley-db/db/gsg/C/index.html" target="_top"> Getting Started with Berkeley DB for C </a> </p> </li> <li> <p> <a href="http://www.oracle.com/technology/documentation/berkeley-db/db/ref/toc.html" target="_top"> Berkeley DB Programmer's Reference Guide </a> </p> </li> <li> <p> <a href="http://www.oracle.com/technology/documentation/berkeley-db/db/api_c/frame.html" target="_top"> Berkeley DB C API </a> </p> </li> </ul> </div> </div> </div> </div> <div class="navfooter"> <hr /> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href="index.html">Prev</a> </td> <td width="20%" align="center"> <a accesskey="u" href="index.html">Up</a> </td> <td width="40%" align="right"> <a accesskey="n" href="introduction.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top">Getting Started with Replicated Berkeley DB Applications </td> <td width="20%" align="center"> <a accesskey="h" href="index.html">Home</a> </td> <td width="40%" align="right" valign="top"> Chapter 1.
