One simple way to do that is...
Once you connect your tables in Tableau, go to a new worksheet. On the data pane (left side) you will see your data tables. Just right click and rename. It will be renamed and also you will see the new name when u go to Data Source tab too.
Hope this helps

I'm not sure if it works for Oracle, but on the data sources I've used if you double click on the table name on the data source tab it should give you the option to change the table name.
Yes actually that worked. Under Data Source tab i double clicked on the name of the table where the mapping is done and it allowed me to rename it. That's the only way it worked for me. Thanks a lot!
