Answer 1

SonarQube didn't install one or many Oracle components. They can be installed during the creation process of the database or after (but always explicitly). SonarQube works perfectly with the minimum and mandatory Oracle components :

1. Oracle Database Catalog
2. Oracle Database packages and Types
3. Oracle XML Database
