How Axis2 function in a clustered environment
Hi All,
I am trying to implement a cluster with 3 nodes using Tomcat and
Axis2. Also i have a state which i write to MessageContext. Thus i
wanted, Axis2 to replicate above MessageContext among all nodes within
the cluster.
To do this i changed Axis2 XML and also attached MessageContext
as a replication context. But it seems the property that i am in serting
into the MessageContext is not visible to other nodes in the cluster.
<stateManager class="org.apache.axis2.clustering.state.DefaultStateManager"
enable="true">
<replication>
<defaults>
<exclude name="local_*"/>
<exclude name="LOCAL_*"/>
</defaults>
<context
class="org.apache.axis2.context.ConfigurationContext">
<exclude name="local_*"/>
<exclude name="UseAsyncOperations"/>
<exclude name="SequencePropertyBeanMap"/>
</context>
<context
class="org.apache.axis2.context.ServiceGroupContext">
<exclude name="local_*"/>
<exclude name="my.sandesha.*"/>
</context>
<context class="org.apache.axis2.context.ServiceContext">
<exclude name="local_*"/>
<exclude name="my.sandesha.*"/>
</context>
<context class="org.apache.axis2.context.MessageContext">
<exclude name="local_*"/>
</context>
</replication>
</stateManager>
I have following questions related to this issue,
1. Can we replicate MessageContexts ? If so how ? Above mentioned
configuration didnt work
2. When does Axis2 nodes are exchanging altered contexts? Ex :- "Is it
before sending a message to a server or after sending a message, etc ...")"
Appreciate if someone can give feedback.
Thank you
AmilaJ

MessageContext state is never replicated. That does not make sense &
is expensive to do since a MessageContext's lifetime is within a
single flow. Replication works only for Service/ServiceGroup/Config
Contexts.
Automatic replication happens in the default MessageReceivers in Axis2
at the end of processing the messages before sending the response to
the client, if full synchronization is set to true. Otherwise, the
response is sent to the client, while the state is replicated
asynchronously.
