Hello! We are experiencing issues when trying to connect the Experience Portal system to our Oracle R12 external database.
Had anyone else experienced this error while trying to configure Oracle External Database for Report Database Settings? 'Report database is missing required columns and must be upgraded'. We created scripts and check few times that all required tables, columns, sequences, indexes, etc were created correctly on our Oracle R12 database.

Error message: Report database is missing required columns and must be upgraded

Avaya version: Avaya Aura® Experience Portal 6.0 (ExperiencePortal)

Path to get to Report Database Settings: Home > System Configuration > EPM Servers > Report Database Settings

Settings:
URL: jdbc:oracle:thin:@<server>.org:1555:<databasename>
JDBC Driver: oracle.jdbc.driver.OracleDriver

I'll appreciate any help!
