Troubleshooting SSL connections
You might query your database and receive the ORA-28860 error.
ORA-28860: Fatal SSL error 28860. 00000 - "Fatal SSL error" *Cause: An error occurred during the SSL connection to the peer. It is likely that this side sent data which the peer rejected. *Action: Enable tracing to determine the exact cause of this error.
This error occurs when the client attempts to connect using a version of TLS that the
server doesn't support. To avoid this error, edit the sqlnet.ora and set
SSL_VERSION to the correct TLS version. For more information, see
Oracle Support Document 2748438.1
