Now I am using Tableau business intelligence tool for data visualization, I tried to connect Oracle database with tableau, at that time I got below Error.
Unable to connect to the server. Check that the server is running and that
you have access privileges to the requested database.

know of service requested in connect descriptor
Unable to connect to the Oracle server "192.176.10.145". Check that the
the server is running and that you have access privileges to the requested
