<title>BDB Store</title>
<para>
The Java broker has an <emphasis>optional</emphasis> message store implementation backed by Oracle BDB JE.
This section will detail where to download the optional dependency from, how to add it to the broker installation,
and provide an example configuration for using the BDBMessageStore.
</para>
<section role="h3" id="Java-Broker-Stores-BDB-Store-BDBJE-Download">
<title>Oracle BDB JE download</title>
<para>
The BDB based message store is optional due to its dependency on Oracle BDB JE, which is distributed under the Sleepycat
licence. As a result of this, the dependency cant be distributed by the Apache Qpid project as part of the broker release package.
</para>
<para>
If you wish to use the BDBMessageStore, then you must download the Oracle BDB JE &oracleBdbProductVersion; release
<ulink url="&oracleJeDownloadUrl;">from the Oracle website.</ulink>
</para>
<para>
The download has a name in the form je-&oracleBdbProductVersion;.tar.gz. It is recommended that you
confirm the integrity of the download by verifying the MD5.
</para>
