Step 10. Configure the Message Broker for B2B Data Exchange High Availability

Step 10. Configure the Message Broker for B2B Data Exchange High Availability

Configure the
B2B Data Exchange
 JMS Broker on both of the cluster nodes.
  1. On both of the cluster nodes, open the JMS Broker configuration file from the following location:
    <
    DX
    InstallationDir>\DataExchange\message-broker\conf\activemq.xml
  2. In the
    <broker>
     element, in the
    dataDirectory
     attribute, enter the name of a shared directory. For example: 
    <broker xmlns="https://activemq.apache.org/schema/core/" brokerName="localhost" dataDirectory="/users/infa/node1" useJmx="true">
    Enter a different directory on each cluster node.
  3. In the
    <broker>
     element, add the following element: 
    <plugins>
 <redeliveryPlugin fallbackToDeadLetter="true" sendToDlqIfMaxRetriesExceeded="true">
<redeliveryPolicyMap>
<redeliveryPolicyMap>
<redeliveryPolicyEntries>
<!-- a destination specific policy -->
<redeliveryPolicy queue="SpecialQueue" maximumRedeliveries="4" redeliveryDelay="10000"/>
</redeliveryPolicyEntries>
<!-- the fallback policy for all other destinations -->
<defaultEntry>
<redeliveryPolicy maximumRedeliveries="10" initialRedeliveryDelay="1000" redeliveryDelay="1000"/>
</defaultEntry>
</redeliveryPolicyMap>
</redeliveryPolicyMap>
</redeliveryPlugin>
</plugins>
  4. In the
    <kahaDB>
     element, in the
    directory
     attribute, enter the name of a shared storage directory. For example: 
    <kahaDB directory="/users/infa/sharedFolder"
                checksumJournalFiles="true"
                checkForCorruptJournalFiles="true" />
    Enter the same directory for both cluster nodes.
  5. In the
    <transportConnector>
     element, in the
    uri
     attribute, enter the IP address of the standard message transfer connector. Enter the same port number that you entered in the
    dx.endpoint.jms.provider.url
     system property, in "Step 4: Configure B2B Data Exchange Properties for High Availability". For example: 
    <transportConnector name="openwire" uri="nio://0.0.0.0:18616?useQueueForAccept=false"/>
    Enter the same IP address and port number for both cluster nodes.
  6. Save the file on both cluster nodes.
