ORAdiff is an Oracle tool designed for comparing two Oracle Database releases, not only core releases but also patch levels. It highlights variations in parameters, privileges, users and roles, reserved words, patch fixes, database homes, objects, and more.
ORAdiff helps answer some common questions:
- When did a parameter was introduced?
- What patch release tweaked a default value?
- Did a bug fix come with a particular Release Update?
- What privileges got stripped from a default role in a specific version?
- Which columns were added in 19.21.0 for a specific CDB view?
How frequently does the ORAdiff information get a refresh?
It is refreshed when a new Release Update is released (every quarter).
