it's a good question, does the Oracle "service" by chance handle SSL internally?
If you're in Tableau Desktop and look at SQL Server (just as an example), it has a checkbox for SSL:
The other option is to choose "other databases" and point at a ODBC entry that you go establish independent of Tableau.
I heard from few of my colleagues that server uses dynamic connection with DB whether it is native drivers or ODBC adapter. So, seems all the communication will be routed through drivers. Hence encryption will be taken care by Tableau itself.
Could you please comment your ideas here.
Thanks in advance,
you can go and submit an idea similar to https://community.tableau.com/ideas/6054
Apparently, this issue has arisen previously with Hadoop and there may be an override option by using tdc which unfortunately at this point I don't know much about.
Apologies for the delay response.Thanks Jeff for your suggestion
