Posted on October 23, 2020 by Mike.Dietrich Auditing Flaws and Pitfalls 10

During my previous test with Unified Auditing Policies anomalies after upgrade to Oracle 19c, I also hit and error when I queried the unified audit trail.

This may become a longer blog post. One of the customers I work with for many years contacted me a few weeks ago. After upgrade to 19c, it looked like as if some Unified Auditing Policies weren’t correct anymore. It started as a tiny issue, but thanks to the customer who analyzed down to the bones, it seems to be bigger than we thought at the beginning. So you may Check your Unified Auditing Policies after upgrading to Oracle 19c as well.

Posted on May 11, 2020 by Mike.Dietrich Operating System 57

Oh … I’d say this was the question I’ve got asked the second most often in the past months (after a potential extension for Oracle 12.2.0.1 support): When will Oracle certify OL8 and RHEL8?
