The ActiveMQ Module Fails to Start

ActiveMQ is used for real-time communication between Administration Console and Access Gateway Service. Real-time communication is needed for commands such as purging cache, gathering statistics, and updating health.

Figure 34-3 Real-Time Communication

When ActiveMQ fails to start, you cannot apply any configuration changes, and Access Gateway does not set a listener for the configured port.

To start, ActiveMQ must be able to resolve the listening IP address to a DNS name. To install Access Gateway Service, the machine must have a DNS name, and the IP address must resolve to this name.
