EM12c: Target Database Shows Status as UP instead of DOWN if the Listener is DOWN in Enterprise Manager 12c Cloud Control (Doc ID 1682141.1)

Last updated on JULY 31, 2014

Applies to:

Enterprise Manager for Oracle Database - Version 12.1.0.1.0 to 12.1.0.6.0 [Release 12.1]
Information in this document applies to any platform.

Symptoms

When a listener on a monitored host is shut down, EM shows the correct status of DOWN for the listener, but a database served by this listener shows a perpetually UP status, even without the listener available.

The status from the database target page still shows as UP, with this message:
