ORA-16635: networkconnection failed during transmission
Cause: The Data Guard broker detected a connection failure toa remote database
in the broker configuration. This failure happened in the middle of atransmission
session. A transmission session usually requires more than one send operationfor
sending a large amount of data (for example, the broker configuration file) tothe
remote database.
Action: Inmost cases, no user action is required. The Data Guard broker always
tries to resend the data. This error will be reported if the problem persists.This
error indicates there are some problems with the network connection between
broker managed databases. Further network troubleshooting should be done to
identify and correct the actual problem.
