Oracle : Ошибка ORA-16622

16622, 0000, "two or more broker database objects resolve to the same database"
*Cause: Multiple database objects referred to the same database.
*Action: Examine the details of all databases in the broker configuration
and verify that there are not two or more databases referring to
the same database. If two or more database profiles in the
broker configuration have the same value for the
DGConnectIdentifier database property, either:
- Remove and re-add the erroneously defined database(s) to resolve
the ambiguity.
- Ensure that the DGConnectIdentifier database property for each
database allows the broker to properly connect to that database.
