Disable Transparent Hugepages on SLES11, RHEL6, RHEL7, OL6, OL7 and UEK2 Kernels

This blog post is not related to database upgrades and migrations. But still I think it is very useful for many customers operating on modern Linux systems. Recommendation  Support just published an ALERT strongly recommending to disable Transparent Hugepages on Linux systems. And the below information does not apply to RAC systems only but also to single instance environments. Which Linux Distrubutions/Kernels are affected?  SLES11 RHEL6 and RHEL7 OL6 and OL7 UEK2 Kernels What are the Issues?  I’m quoting MOS Note: 1557478.1 (ALERT: Disable Transparent HugePages on SLES11, RHEL6, RHEL7, OL6, OL7 and UEK2 Kernels): Because Transparent HugePages are known…

SuSE SLES 12 certified with Oracle Database 12.1.0.2

MS Windows Bundle Patches – a VERY different story

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 for an earlier delivery. So…
