As you know, this blog is also my brain dump about Oracle topics.

Oracle 18.3.0 Multitenant: Compatibility Check does not work When I changed our Hands-On Lab to Oracle 18c, I encountered one strange issue in case I upgraded the UPGR database to 18.3.0 and wanted to plug it in afterwards. Before plugin I usually do a compatibility check. But this seems to fail. I checked my file, my paths, everything. But I couldn’t find the root cause. And yesterday I received an email from a customer who has a case open for over a week encountering a similar problem.
