        Tweaked documentation so the notice only refers to a single jira, and reflects that
as of right now GERONIMO_HOME/repository is shared among instances.<br />

fixes an issue with ActiveMQ that previously prevented Geronimo javaee6 from running multiple
instances. Though multiple instances of Geronimo javaee6 can now be started, it is still undergoing
testing in scenarios following this documentation. And several issues are identified in [GERONIMO-6174|https://issues.apache.org/jira/browse/GERONIMO-6174]
and [GERONIMO-6175|https://issues.apache.org/jira/browse/GERONIMO-6175]. Refer to [GERONIMO-5987|https://issues.apache.org/jira/browse/GERONIMO-5987]

for the progress on re-enabling multiple instance support. <br> <br>For the Geronimo
minimal release bundles, though it is possible to startup multiple instances, the known issues
to do so safely are shared with those identified in [GERONIMO-6174|https://issues.apache.org/jira/browse/GERONIMO-6174],

<p>It is possible to run multiple instances of Geronimo on the same machine. Currently
multiple instances of Geronimo share the following directories in <tt>&lt;geronimo_home&gt;</tt>,
the directory where you installed Geronimo. These are read-only.</p>
<ul>
	<li>bin</li>
	<li>jsr88</li>
	<li>lib</li>
	<li>schema</li>
</ul>


<p>The repository is shared, and contains lots of basic and important libraries are
required to bootstrap server. It is possible to configure second repositories, one fore each
instance. See <a href="/confluence/display/GMOxDOC30/Configuring+multiple+repositories"
title="Configuring multiple repositories">Configuring multiple repositories</a>.</p>
<ul>
	<li>repository</li>
</ul>


<p>Each instance gets its own copy of the following at <tt>&lt;geronimo_home&gt;/&lt;instance_name&gt;</tt>
. These are read-write and are necessary for each Geronimo instance.</p>
<ul>
	<li>etc</li>
	<li>var</li>
</ul>


<p>These are also read-write but are not part of the minimally necessary directories
and files for running a Geronimo instance, but may be desired. The deploy directory will be
automatically created when you start Geronimo if it does not already exist.</p>
<ul>
	<li>repository  (this is not the same as the primary shared repository)</li>
	<li>deploy</li>
	<li>hotbundles</li>
</ul>


<p>The bin, lib and schema directories are read-only, and thus are shared between instances.
The repository is not shared, which means that an application deployed in one instance will
only show up in the list of deployed modules of the deployed instance.</p>

<h1><a name="RunningmultipleGeronimoinstances-Creatinganewserverinstance"></a>Creating
a new server instance</h1>

<p>Start with a fresh image of Geronimo. Do not use an image that has been used to run
the default instance.</p>

<p>To create an instance named <tt>foo</tt> do the following. All your instance
data will be put in <tt>&lt;geronimo_home&gt;/foo</tt>. All the directories
named below are relative to <tt>&lt;geronimo_home&gt;</tt>.<br/>
Follow the procedures as below:</p>
<ol>
	<li>Create a directory <tt>foo</tt> under <tt>&lt;geronimo_home&gt;</tt>.</li>
	<li>Copy <tt>var</tt> and <tt>etc</tt> directories to <tt>foo</tt>.
You can use the command <a href="/confluence/display/GMOxDOC30/gogo+commands+for+Geronimo#gogocommandsforGeronimo-gogocommandsforGeronimogogocommandnewserverins...">deploy:new-server-instance</a>
to help you with this step.</li>
	<li>Optionally create <tt>foo/repository</tt> and set it up as a second
repository for the Geronimo instance.</li>
	<li>Edit <tt>foo/var/config/config-substitutions.properties</tt> and change
the portOffset. Try using any integers such as 1, 2, 10, 20, 30.. for various instances.</li>
</ol>



<h1><a name="RunningmultipleGeronimoinstances-Runninganinstance"></a>Running
an instance</h1>

<ol>
	<li>Set the <tt>org.apache.geronimo.server.name</tt> system property to
define a server name before you start the server. This system property is null by default,
defining the server instance at <tt>&lt;geronimo_home&gt;</tt> as the
default instance. Use the syntax <tt>&#45;Dorg.apache.geronimo.server.name=foo</tt>
to change the server name to an instance named <tt>foo</tt> located at <tt>&lt;geronimo_home&gt;/foo</tt>.
Add this to your <tt>GERONIMO_OPTS</tt> environment variable:</li>
</ol>


<ul>
	<li>On a Windows system: <tt>set GERONIMO_OPTS=-Dorg.apache.geronimo.server.name=foo</tt></li>
	<li>On a Unix-like system: <tt>export GERONIMO_OPTS=-Dorg.apache.geronimo.server.name=foo</tt></li>
</ul>


<ol>
	<li>Start the server using startup
<div class="preformatted panel" style="border-style: solid;border-width: 1px;"><div
class="preformattedContent panelContent">
<pre>&lt;geronimo_home&gt;/bin/startup
</pre>
</div></div></li>
	<li>To shutdown this instance, use the port number of RMI Naming port (default 1099).
For the new instance <tt>foo</tt>, the port number should be 1099 plus portOffset
specified in <tt>foo/var/config/config-substitutions.properties</tt>.
<div class="preformatted panel" style="border-style: solid;border-width: 1px;"><div
class="preformattedContent panelContent">
<pre>&lt;geronimo_home&gt;/bin/shutdown --port &lt;port_num&gt;
</pre>
</div></div></li>
	<li>To deploy applications to this instance use the port number of RMI Naming port
<div class="preformatted panel" style="border-style: solid;border-width: 1px;"><div
class="preformattedContent panelContent">
<pre>&lt;geronimo_home&gt;/bin/deploy --port &lt;port_num&gt; deploy
&lt;applications&gt;
</pre>
</div></div></li>
</ol>


<p>The Administrative Console can also be used for all these operations. Connect to
an instance by using the right HTTP port (default 8080).</p>

<h2><a name="RunningmultipleGeronimoinstances-Exampleruntimeformultipleinstances"></a>Example
runtime for multiple instances</h2>

<ul>
	<li>First download the Geronimo bundle distribution</li>
	<li>Determine what you want <tt>GERONIMO_HOME</tt> to be. We will use <tt>/opt/geronimo3</tt>
for this example.</li>
	<li>Unpack the Geronimo bundle, and move the unpacked directory to <tt>/opt/geronimo3</tt></li>
	<li>We'll create two Geronimo instances named gserv1 and gserv2
	<ul>
		<li>Create the Geronimo instance directories as <tt>/opt/geronimo3/gserv1</tt>
and <tt>/opt/geronimo3/gserv2</tt></li>
		<li>Copy the directories <tt>var</tt>, <tt>etc</tt>, and <tt>repository</tt>
to each instance directory</li>
		<li>Modify the <tt>gservN/var/config/config-substitutions.properties</tt>
file for each Geronimo instance changing the <tt>PortOffset</tt>. We'll set the
<tt>PortOffset</tt> for <tt>gserv1</tt> to 100 and the <tt>PortOffset</tt>
for <tt>gserv2</tt> to 200 for our example.</li>
		<li>Create a start script in each Geronimo instance directory to make it easier to
start each instance
		<ul>
			<li><tt>/opt/geronimo3/gserv1/start.sh</tt>
<div class="preformatted panel" style="border-style: solid;border-width: 1px;"><div
class="preformattedContent panelContent">
<pre>#!/bin/bash
# Geronimo start script

# Interactive startup

</div></div></li>
		</ul>
		</li>
		<li>On linux, make the start script is executable with chmod: chmod 755 start.sh</li>
	</ul>
	</li>
	<li>Your Geronimo installation file structure should look something similar to this:
<div class="preformatted panel" style="border-style: solid;border-width: 1px;"><div
class="preformattedContent panelContent">
<pre>/opt/geronimo3
|-- LICENSE
|-- NOTICE
|-- README.txt
|-- RELEASE_NOTES-3.0-SNAPSHOT.txt
|-- bin
|-- deploy
|-- etc
|-- gserv1
|   |-- etc
|   |-- repository
|   |-- start.sh
|   `-- var
|-- gserv2
|   |-- etc
|   |-- repository
|   |-- start.sh
|   `-- var
|-- hotbundles
|-- jsr88
|-- lib
|-- repository
|-- schema
`-- var
</pre>
</div></div></li>
	<li>Finally you can start up each instance by executing their associated start script
you just created in the previous step</li>
</ul>
