Getting Data Guard alarms for a decommissioned standby database (4252966)

After decommissioned an Oracle standby database from the primary database, Data Guard alarms are still being triggered and the "Data Guard Destination Status" object still exists. When deleting the object, it will return within the next collection interval.

In order to find if a Data Guard exist for an instance, the agent execute the following query:

select count(*) dataguard from sys.v_$archive_dest where target = 'STANDBY';

If the result count > 0, the agent will execute the Data Guard collections.

Run the query and according to the result, clean up the primary database from remaining Data Guard configuration.
