Apply the kernel patch0012 Carbon patch. The patch includes a modification in the Carbon Core component, allowing it to add third party membership schemes.
Info
For more information, see WSO2 patch application process.
Copy the following JAR files to the /dropins directory of the Carbon server:
- activemq_client_5.10.0_1.0.0.jar
- geronimo_j2ee_management_1.1_spec_1.0.1_1.0.0.jar
- hawtbuf_1.9_1.0.0.jar
- org.apache.commons.lang3_3.1.0.jar
- org.apache.stratos.common-4.1.0.jar
- org.apache.stratos.messaging-4.1.0.jar
- private-paas-membership-scheme-4.1.0.jar

Update the <PPAAS_HOME>/repository/conf/axis2.xml file with the following configurations:

Info
The cluster ID parameter needs to contain the cluster ID of the relevant carbon server cluster:

Code Block

<clustering class="org.wso2.carbon.core.clustering.hazelcast.HazelcastClusteringAgent" enable="true">
    <parameter name="membershipScheme">private-paas</parameter>
    <parameter name="membershipSchemeClassName">org.wso2.carbon.ppaas.PrivatePaaSBasedMembershipScheme</parameter>
    <parameter name="clusterIds">cluster-1,cluster-2</parameter> 
    <parameter name="localMemberPort">4000</parameter>  
</clustering>

Note
When using Private PaaS with the `private-paas` membership scheme, update the `localMemberPort` property in the `axis2.xml` file, because the `private-paas` membership scheme uses the default port - 4000.

Update the JNDI configuration of the product to include the message broker configuration for the PPaaS Membership Scheme to connect to. Point the java.naming.provider to the AMQP port of the message broker.
