EM 12c, EM 13c: How to Delete a Database and Listener Target in Enterprise Manager Cloud Control (Doc ID 1905181.1)

Last updated on AUGUST 02, 2019

Applies to:

Enterprise Manager for Oracle Database - Version 12.1.0.1.0 and later
Information in this document applies to any platform.

Goal

How to delete a database target from the console in Enterprise Manager 12c or 13c Cloud Control:

Deleting a database target from the console in Enterprise Manager Cloud Control, does not actually delete the database itself.  It just removes the database target from the Cloud Control Console, which means that this particular database will no longer be a target managed by Cloud Control.  There are reasons why a database needs to be removed (deleted) from Cloud Control.  For example, if the name (as displayed in the Cloud Control Console) needs to be changed.  Or if the actual database itself has been removed, and is no longer a valid target.  Please note that when a database target is deleted from Cloud Control, all the historical metric values and job history associated with that target are also deleted.  So this should only be performed, if job history and metric history is not needed.
