In order to obtain data from a server, there must be an active Listener. Most IBM products that support the IBM® System Dashboard for Enterprise Content Management functionality, such as Content Platform Engine, IBM FileNet® Image Services Resource Adapter, and other applications, enable the Listener (that is, make it active) by default.
On a FileNet Image Services server, perform these steps to activate the listener. On FileNet Image Services systems, the Listener is off by default. On other systems, the Listener is on by default.
