We have a environment of Vertica+Tableau. We have TDC file on our locals and on tableau server.
I want to prevent multiple sessions. To test this I added the line to my local TDC file and via tableau desktop connect to vertica. "<customization name='CAP_MULTIPLE_CONNECTIONS_FROM_SAME_IP' value='no' />"
But I still can send two queries. Is changing local TDC and make a connection to database not enough for the test?
I am not 100% sure but I believe that when you use this setting and connect twice one of the connections will be dropped but you won't get an actual error message.
You could always check on your database if the sessions are both still opened.
