Oracle : Ошибка ORA-16665

16665, 0000, "timeout waiting for the result from a database"
*Cause: The Data Guard broker was forced to time out a network connection
to a remote database because:
- The network call to the remote database did not complete in
a timely manner.
- The remote database was unable to execute the command due to
an instance failure.
*Action: Check Data Guard broker logs for the details of the failure.
If the network call did not complete in a timely manner, increase
the CommunicationTimeout configuration property value and reissue
the command.
