From Database 18.3 to 18.5 (on Windows)

Contrary to wild rumours on the internet, it was not a fear of the number 13 that led to a numbering jump from version 12c to version 18c. The jump was part of our new, more flexible release mechanism so that we can get…

Happy Thanksgiving!

Just a quick blog post from Wellington New Zealand where we have just wrapped up the 2018 APAC Groundbreakers tour. It was a great way to finish the event with a small but enthusiastic crowd here in New Zealand. Obviously our American counterparts in…

18c and the ignoring of hints

  One of the new features in 18c is the ability to ignore any optimizer hints in a session or across the entire database. A motivation for this feature is obviously our own Autonomous Data Warehouse, where we want to optimize queries without the…

18c XE–running locally

UTL_FILE_DIR and 18c

I wrote a blog post called The Death of UTL_FILE which attracted a comment from a reader: “There is NO chance to stay at UTL_FILE as it is DESUPPORTED starting with database Version 18c” This is not the case, but since I wanted to…

18.2 patch… painless for me

18.2 was released a few days ago, so I thought I’d throw it against my 18c instance and see how things played out.  This was just a single instance database, running with a single pluggable. Step 1 for me was to download the latest…
