ORA-16796: one ormore properties could not be imported from the database
Cause: The broker was unable to import property values forthe database being
added to the broker configuration. This error indicates:
- The Oracle Net service name specified in DGMGRL CREATE CONFIGURATION
or ADD DATABASE command was not one that provides access to the database
being added.
- There were no instances running for the database being added.
Action: Removethe database from the configuration using the REMOVE
CONFIGURATION or REMOVE DATABASE command. Make sure that the
database to be added has at least one instance running and that the Oracle Net
service name provides access to the running instance. Also check the broker log
file for additional information. Then, reissue the CREATE CONFIGURATION or
ADD DATABASE command.
