Posted on September 28, 2026 by Flaws and Pitfalls Microsoft Windows Patch Recommendation 21

Several of you mailed me already, and I tried to sort this out internally at first. We ask you to patch monthly, and it is amazing to see that some of you are ready to do this.

What has been changed?

So at first, thanks to Ernst and Marcus for bringing this to my attention. This is an issue which happens on MS Windows only.

ORA-1722 when upgrading to 19.4.0 or 19.5.0 on Windows

Posted on December 18, 2019 by Flaws and Pitfalls 17

Oh boy – I try to avoid blogging about errors on a specific platform. But as this topic was brought to my attention now 3x in 2 weeks, I think I’ll send it out. And I hope you won’t hit this ORA-1722 when upgrading to 19.4.0 or 19.5.0 on Windows.

MS Windows Bundle Patches – a VERY different story

Posted on January 28, 2014 by Operating System Patch Recommendation 0

I like Upgrade Workshops for a very different reason:
Hopefully people feed back with questions and information I wasn’t aware off before. So for myself these workshops are also a learning experience. And thanks to a customer in Singapore (Thanks a lot, Hanh!!) I learned something about Oracle’s Bundle Patches for MS Windows.

Customer asked about a specific issue when using RMAN Duplicate command in 12c failing with a nice ORA-600 [KSRPCSEXEC_1]. This got logged a while ago as bug16883554 – and it will be fixed in database patch set 12.1.0.2. But this customer asked …
