Oracle Solution for Error ora-16625

ORA-16625: cannot reach the database

What triggered the Error:

The command could not be executed because the database required to complete the command was not reachable from the database where the command was issued. If the command modifies the configuration, the command must be processed by the copy of the broker running on an instance of the primary database.

What should we do to fix it:

Check the network connections between all of the databases in the configuration. Alternatively, connect to a different database in the Data Guard broker configuration and retry the command. If an attempt was made to determine the status of a particular database in the configuration, connect to that database and get the current value of the StatusReport property for that database.
