<p>It is relatively straightforward to run the ActiveMQ broker on z/OS.</p>

<p>There are a couple of steps:</p>

<p>   1. Copy ActiveMQ to z/OS<br clear="none">
   2. Modify the configuration<br clear="none">
   3. Run using JZOS<br clear="none">
   4. Test</p>

<h3 id="zOS-CopyActiveMQtoz/OS">Copy ActiveMQ to z/OS</h3>

<ul><li>Ensure that the 1.5 JVM is available on z/OS, together with the <a shape="rect" class="external-link" href="http://www.dovetail.com/docs/jzos/index.html" rel="nofollow">JZOS</a> component.</li><li>Download the .zip version of ActiveMQ from Apache.</li><li>FTP the broker to a suitable directory in USS.</li><li>Log into USS using rlogin or whatever has been configured at your site to do a login into USS.</li><li>Extract the zip file using the command: jar -xvf apache-activemq-5.0.0.zip</li><li>This will extract the whole package in ASCII, so do not except any of the files to be viewable on z/OS, except using special editors suitable for ASCII.</li><li>Maybe rename the directory to which the files were extracted to something shorter or create a softlink for more convenient access.</li></ul>


<h3 id="zOS-Modifytheconfiguration">Modify the configuration</h3>

<p>Currently, the Jetty plugin does not work on z/OS, so need to be disabled in the activemq.xml file.</p>

<ul><li>FTP the activemq.xml file from the conf directory in the ActiveMQ installation to your PC in binary mode.</li><li>Edit the XML file using your XML editor or a text editor like Wordpad.</li><li>Search for "jetty" in the XML.</li><li>Change the comment block so that jetty is completely commented out.</li><li>Save the file.</li><li>FTP the file back into the location on z/OS it came from, again in binary mode, so that it is preserved as an ASCII file.</li></ul>


<h3 id="zOS-RunusingJZOS">Run using JZOS</h3>

<p>I have renamed the lib/optional directory in USS and shortened some of the lib/optional jar names to make the JCL easier to handle. The JCL to run the ActiveMQ broker is then:</p>

<p>Once the broker has been started on z/OS, modify one of the example application to have the hostname of the z/OS system and run it to confirm that the broker is functioning correctly.</p>

<p>You can also gather information about the broker as usual using <a shape="rect" href="jmx.html">jmx</a>.</p></div>
