Campaign listener requirements
The Campaign listener requires that Marketing Platform be running.
The listener connects to Marketing Platform using the value of the configurationServerBaseURL property in the config.xml file, located in the conf directory of your Campaign installation. Typically, this value is http://hostname:7001/Unica. If Marketing Platform is not running, the Campaign listener will fail to start.
As the listener is dependent on Marketing Platform to start successfully, you should ensure that your web application server is running and the Marketing Platform web application is deployed before starting the listener.
