Reports Server is automatically registered with Oracle Enterprise Manager during installation of Oracle Fusion Middleware.
If you add any Reports Servers or other Oracle Reports components after installing Oracle Fusion Middleware, do the following:
Restart the WLS_REPORTS managed server by stopping it and and start it again. This is necessary for completing registration of the new Reports Server configuration MBeans.
Refresh the Oracle Enterprise Manager page to make the new Oracle Reports components available in Oracle Enterprise Manager.
