ORA-16697
current role of the member only allows a LOCAL rule in RedoRoutes property
Cause
A logical or snapshot standby database was specified as a redo data source in a RedoRoutes configurable property rule.
Action
Logical and snapshot standbys cannot be configured as a redo source. The only valid rules a logical or snapshot standby database can contain are those that specify LOCAL or its database unique name value in the redo source field of a redo routing rule. Check that the member for which you are setting the RedoRoutes configurable property is a primary database, physical standby database, or a far sync instance.
Note that a Oracle Zero Data Loss Recovery Appliance cannot be a redo source.
