Issue/Introduction

How to find out what TLS version is used when a client application connects to a TIBCO Data Virtualization server?

Resolution

To see the TLS version used when a client connects to TDV (via ODBC, Power BI, or any anything else), you can do the following:

(1)  Turn on SSL tracing as follows:
  • Set Studio > Administration > Configuration > Server > Communications > Generate SSL Diagnostics (On Server Restart) to True
User-added image
  • Restart the TDV (TIBCO Data Virtualization) Server
(2)  Open a connection from the client.

(3)  An SSL trace will be logged to either cs_server.out or cs_monitor.out. Look for the string "TLS" in these  logs. The trace will contain several lines with the TSL version, for example:

----------------------
21727 javax.net.ssl|DEBUG|3C|DbChannel-RequestSelectThread|2021-08-25 16:14:16.532 PDT|SSLEngineInputRecord.java:214|READ: TLSv1.2 handshake, length = 184
