SQL*Net Listeners (PD_PDLS)
- Organization of this page
Function
The SQL*Net Listeners (PD_PDLS) record stores performance data indicating the status and overview of each defined listener at a specific point in time. PFM - Agent for Oracle creates one record for each name specified in listener_name. Only one listener can be monitored.
If you omit the listener name when setting an instance, PFM - Agent for Oracle monitors the default listener. If the listener is not active, the Alias field is blank.
If SQL*Net has not been installed, an attempt to display a report that uses this record will display the No records returned message.
- Notes
-
When setting an alarm monitoring SQL * Net Listeners (PD_PDLS) records, if you set the name of a listener that does not exist in the listener_name of the instance information, the Listener Status alarm status will always be normal. Upon the occurrence of this phenomenon, the following message is output to the common message log:
KAVF12412-W The listener does not exist. (ListenerName=listener-name)
If this message is output, correct the LISTENER_NAME property value.
