Hey there!
If your users run into this issue
https://kb.tableau.com/articles/issue/error-ora-21561-oid-generation-failed-connecting-to-oracle-from-mac
"Error "ORA-21561: OID generation failed" Connecting to Oracle with a Mac"
Tableau has a solution, edit the hosts file to include local computer name by adding the computer name to the end of the 127.0.0.1 line
Which is wonderful! and helped us out. But we did not want users to have to edit this manually. So we made a script and deployed it to Tableau users via self service.
This script will add the entry, or remove it if the entry is already there. It uses jamf helper to show the user a nice notification window
