Oracle Listener (ORANET_LISTENER)

Displays information about an individual listener process. ORANET_LISTENER is available once the ORANET listener has been configured.
The ORANET_LISTENER icon is labelled LISTENER or <listenername>.

The ORANET_LISTENER application class also monitors the scan listeners. When the scan listeners move from one Real Application Cluster Node to another, the KM will create the SCAN listener on that node.

 In this Oracle km version, we changed the configuration of excluding listeners. In previous versions we have the option to enable/disable listeners from the configuration window, where we add listener. In this release we have removed this option and added new KM command and CMA configuration for this purpose.

You have an option to enable/disable listeners according to listener name or regular expression. 

Listener Services

The listener services will be created under each listener. To get the listener services we run the following from ORACLE_HOME/bin:

>./lsnrctl services {listener name}

We added the option to enable/disable listener services. By default all listener services will be enabled. You can filter out from KM menu command or CMA. You can filter from root level or listener level.

If the listener has its filtered services list, then we take into consideration this filter, in case the listener has no filter on services we take into consideration the root level filter.

Root filter is done from ORANET application class or Global configuration of listeners on CMA. The listener filter is done from listener application class, and listener configuration in CMA.

Root Level (ORANET)

In this level you can filter out listener services for ALL listeners. You have the option to drag right and left listeners according to which you want to enable or disable.

Other option is using regular expression. The priority of the filter is for dragging list, in case you need to use regular expression , then all the services must be in active list.

Listener Level 

Set the filter you want to do , you have the following option:

1. Check box of "Include all". This option is added to display all the listener services and to avoid the root filter.
2. KM:  Drag to left and right the services you want to enable/disable. 
   CMA: Add the list on CMA separated with comma
3. Use regular expresion.

When the "ListenerStatus" runs the services filter will be handles and add/destroy services according to the filter.
