Yes. In the axis2.xml file, we do have configuration as
*<clustering
class="org.wso2.carbon.core.clustering.hazelcast.HazelcastClusteringAgent"*
* enable="true">*
But in Stratos load balancer configuration file dose not have
group_mgt_port.
# services {
# app-server { # service name, a unique identifier to identify a
service
# multi-tenant: true; # Set to true if the service is
multi-tenant
# clusters {
# app-server-cluster1 { # cluster id, a unique identifier
to identify a cluster
# hosts: cluster1.appserver.foo.org, cluster1.org; #
comma separated hostname list
# tenant-range: 1-100; # Tenant range of the cluster
# algorithm: round-robin; # algorithm name
# members {
# m1 { # member id, a unique identifier to
identify a member
# ip: 10.0.0.10; # member ip address
# ports {
