<p>If you run in an OSGi environment such as <a shape="rect" href="http://servicemix.apache.org">ServiceMix 4</a> then take a look at <a shape="rect" href="http://servicemix.396122.n5.nabble.com/ServiceMix-4-2-Camel-OracleAQ-td421214.html#a421214">this discussion</a> how to install the OracleAQ Client in the OSGi container.</p>

<h4>Oracle SQL code</h4>
<p>You may need to setup OracleAQ, and here is a sample code</p>
<structured-macro ac:macro-id="efdb1a06-1164-41a6-86ee-ce8b6fc792b7" ac:name="code" ac:schema-version="1"><plain-text-body>
BEGIN
 DBMS_AQADM.CREATE_QUEUE_TABLE( queue_table =&gt; 'queue_message_table', queue_payload_type =&gt; 'SYS.AQ$_JMS_TEXT_MESSAGE');
END;        

BEGIN
  DBMS_AQADM.CREATE_QUEUE( queue_name =&gt; 'ORACLE_QUEUE', queue_table =&gt; 'queue_message_table');
END;

BEGIN
  DBMS_AQADM.START_QUEUE(queue_name =&gt; 'ORACLE_QUEUE');
END;
