Version control for Oracle databases

I'm setting up a version control for several databases. There are some objects like functions/procedures/packages that appear in all the databases, that is, each such object has an identical instance in each database. In the current solution, all these objects are just (re)deployed in every database separately. But for sure there must be a better way to make the version control run more automatically by using the fact that all these databases have (copies of) the same objects. I will be very thankful for any clue!
