18.2 patch… painless for me

Posted by

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 OPatch.  To be honest, I don’t even check whether I already have the latest version in any installed ORACLE_HOME anymore.  If I’m going to apply a patch, I’m always going to download the latest OPatch unless the README explicitly tells me some reason why I should not.  I figure getting the latest version reduces the chances I’ll hit problems.  For me, I grabbed version “”, but your experience may differ depending on when you encountered upon this post.

So I then downloaded patch 27676517 (note, this does not include patches for the JVM which are done separately).

From there is was just a case of following the README instructions and I had no dramas at all.  Software patching went through smoothly:

OPatch succeeded.


And the datapatch stage to update the database(s) also went through without any problems.

So all in all, a painless and straightforward experience for me.

One minor annoyance for me was the “Bugs Fixed” document.  The README references this as:


but that document is not accessible currently.  However, if you follow a different link in the README


then you will get to the document which contains the list of fixes etc.

Footnote: If you are not familiar with the new nomenclature of “Patch”, “Release Update”, etc etc, here is a good place to start


and follow the various links within that post for more information.

Happy upgrading!

Addenda: When it comes to the ‘datapatch’ script, the README is perhaps a little ambiguous.  More on that here




  1. Butbutbutbut……
    I thought that with the 18c release in the cloud, there was no need for anyone to have a dba install software or upgrade it?
    It was all supposed to happen like magic?

    Silly me!
    Or rather, silly Lazza…

  2. Very nice, I think you may mention that it needs to download OPatch patch of version for Oracle software releases DB 12.2.0.x and DB 18.x (APR 2018).

    Thank you..
