Enabling communication among Content Deployer instances
In a setup with a scaled-out Content Deployer, configure a JMS Adapter in the configuration of each Content Deployer instance. You must have Apache ActiveMQ or AmazonSQS up and running for this functionality. You additionally need to have set up shared access to a common Redis database for storage of binary data.
Procedure
What to do next
If you want to monitor the JMS queue you have set up, you can use the ActiveMQ Web console at http://MQHOST:8161/, where MQHOST is the hostname of your ActiveMQ server. For more information about the Web console, refer to the ActiveMQ documentation at http://activemq.apache.org/web-console.html.
