ORA-16635: NetSlave connection was broken in the middle of a transmission session

Cause: The Data Guard NetSlave process detected a connection failure to a remote database in the broker configuration. This failure happened in the middle of a transmission session. A transmission session usually requires more than one send operation for sending a large amount of data (e.g. the broker configuration file) to the remote database. This error implies the transmission has to be restarted from the beginning.

Action: In most cases, no user action is required. The Data Guard broker always tries to resend the data from the beginning. If the problem persists, the user will eventually see this error reported. This will indicate there are some problems with the network connection between broker managed databases. Further network troubleshooting should be done to identify and address the actual problem.
