I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Should reference this to minimally reach the console to list out the cipher string
... and on the server, those cipher entries should be available in the server (e.g."$ORACLE_HOME/network/admin/sqlnet.ora") file and in listener (e.g. $ORACLE_HOME/network/admin/listener.ora")  to accept SSL/TLS encrypted connections is to sniff the actual traffic - has to look at protocol version for TLS 1.2 like in this snapshot
...and to drill into pcap raw packet content you will see the version as 0303 as per rfc 5246, for TLS1.0 it is as stated
the first three fields of an "Application Data" record are:
•Content Type (0x17 to indicate Application Data)
•Protocol Version (0x0301 for TLS1.0, et al)
•Record Length (length in Bytes of encrypted content)
