Are Bundle Patches (BPs) and Patch Set Updates (PSUs) cumulative?
That is a question sounding trivial to many people but actually it does get asked quite often. And sometimes I forget to mention this during the workshops - and luckily usually somebody asks the question reminding me to explain it.
Yes, Bundle Patches and Patch Set Updates (and of course Proactive Bundle Patches and Critical/Security Patch Updates (CPUs/SPUs) are all cumulative.
You'll find this mentioned in the first paragraph of MOS Note: 854428.1 - Patch Set Updates for Oracle Products:
Interesting note on the side:
I would have expected this important piece of information in MOS Note:1962125.1 - Oracle Database - Overview of Database Patch Delivery Methods but I couldn't find it. So it's no wonder why people ask such a trivial question ... [irony!]
Two simple examples:
- You have the October 2015 PSU applied
- You'd like to apply the April 2016 PSU on top
- Then you don't need the January 2016 PSU as it is included in the April 2016 PSU already
- You never applied a Procative Bundle Patch
- You'd like to apply the April 2016 Proactive Bundle because a guy recommended it on an Oracle blog - and actually MOS notes mention it as well as highly recommended
- You don't need to apply anything beforehand.
The April 2016 Proactive BP has all the fixes from all previous BPs included on top of Oracle Database 188.8.131.52.0
