- Open the
<ESB_HOME>/repository/conf/axis2/axis2.xmlfile. - Locate the Clustering section and verify or configure the properties as follows (some of these properties are already set correctly by default):
- Enable clustering for this node:
<clustering class="org.apache.axis2.clustering.tribes.TribesClusteringAgent" enable="true"> - Set the membership scheme
- Enable clustering for this node:
...
- to
wka
- to
...
- to enable the Well Known Address registration method (this node will send cluster initiation messages to WKA members that we will define later):
<parameter name="membershipScheme">wka</parameter> - Specify the name of the cluster this node will join:
<parameter name="domain">wso2.esb.domain</parameter> - Specify the name of the cluster this node will join:
<parameter name="domain">wso2.as.domain</parameter> - Specify the port used to communicate cluster messages:
<parameter name="localMemberPort">4001</parameter>

- This port number will not be affected by the port offset
...
- in
carbon.xml. If this port number is already assigned to another server, the clustering framework will automatically increment this port number. However, if two servers are running on the same machine, you must ensure that a unique port is set for each server. The receiver's http/https port values are without the
portOffsetaddition; they get auto-incremented byportOffset. The 'WSDLEPRPrefix' parameter should point to the worker node's host name (esb.cloud-test.wso2.com) and ELB's http (8280)/https (8243) transport ports.Ensure that you set the value of the subDomain as mgt to specify that this is the manager node, which will ensure that traffic for the manager node is routed to this member.
