Message property</a> as it was explained earlier. After all the messages up

cannot be used any more. There are basically two ways a sequence can time
out, and both can be configured using policies. See '<a href="#inactivitytimeout">InactivityTimeout</a>' and '<a href="#maximumretransmissioncount">MaximumRetransmissionCount</a>' parts of

+<p>Sandesha2 provides a set of configurations which you can use to customize
its execution behavior. All these configurations are available in a WS-Policy
format. These policies can be in the module.xml file of the Sandesha module
or in the services.xml file of a service on which Sandesha2 module has been
engaged. Most of the policies in the module.xml can be overridden by setting
different values in a services.xml. But some policies cannot be overridden
and must be set correctly in the module.xml file.</p>
+
<p>You will find each Sandesha2 policy and the way an alteration of it can
effect Sandesha2. Make sure that you set these values carefully. Setting
incompatible types or values may cause Sandesha system to malfunction.
Normally if Sandesha2 can detect that the value you have set is incompatible,
it will set a default value which is mentioned in the SandeshaConstants
class.</p>

<p>PermanentStorageManager - Will be storing data in a database. So will be
little slower but real business applications will most probably prefer this
