James,
Same test will apply for Oracle 11/12. You still need to confirm at the Universe level that the Objects is working properly. Also confirm you are using proper supported driver based BI 4.1 PAM.
Confirm you have proper version of Oracle 32/64bit driver is installed. You need to use NATIVE DRIVER, just like MS SQL.
- What's exact version BI 4.1 are you running?
- What's exact version of Oracle driver?
- What's exact version of Oracle DB and on what OS?
Regards,
Ajay
