The certification is finally done with Oracle 220.127.116.11 and RHEL 7.1. It’s highly recommended that you upgrade to the latest fixpacks though. Read more in the IBM Flash or go directly to Oracle support and read the Oracle Note (requires Oracle login):
- 1967531.1: “Requirements for Installing Oracle 18.104.22.168 RDBMS on RH7 on IBM: Linux on System z (s390x)” – which has detailed installation instructions, which are a must read before trying to install.
As usual with Oracle certifications RHEL 7.1 is the minimal level required.
