<h1>JMS Colocated Failover Shared Store Example</h1>
|
|
<pre>To run the example, simply type <b>mvn verify</b> from this directory. This example will always spawn and stop multiple servers.</pre>
|
|
|
|
<p>This example demonstrates how you can colocate live and backup servers in the same VM. We do this by creating an
|
|
HA Policy that is colocated. colocated means that backup servers can be created and maintained by live servers on behalf
|
|
of other requesting live servers. In this example we create a colocated shared store server.
|
|
<p>This example starts 2 live servers each with a backup server that backs up the other live server.</p>
|
|
<p>The first live server will be killed and the backup in the second will become live</p>
|
|
<p>The following shows how to configure the live servers to request and allow backups to be deployed</p>
|
|
<pre class="prettyprint">
|
|
<code><ha-policy>
|
|
<shared-store>
|
|
<colocated>
|
|
<backup-port-offset>100</backup-port-offset>
|
|
<backup-request-retries>-1</backup-request-retries>
|
|
<backup-request-retry-interval>2000</backup-request-retry-interval>
|
|
<max-backups>1</max-backups>
|
|
<request-backup>true</request-backup>
|
|
<master/>
|
|
<slave/>
|
|
</colocated>
|
|
</shared-store>
|
|
</ha-policy>
|
|
</code>
|
|
</pre>
|
|
<p>notice that we have used a template to set some sensible defaults but overridden the backup strategy so back ups
|
|
are full servers</p>
