How to patch Linux o/s with least down time to Oracle database

edited Aug 19, 2017 5:00AM in Database Administration (MOSC) 1 commentAnswered

Hello,

I like to know which method would have the least down time for the Oracle Database server when the Linux o/s needs to be patched.

For example, I have a Linux vm that hosts a standalone 12c database.  The Linux is in need of patching.  I am exploring ways to patch the Linux o/s with the least impact( down time) to the Database.  The storage and ORACLE_HOME are on shared storage.  What if we clone the existing Linux host to another vm.  Then on this cloned vm, we then perform the patch of the o/s.  Then after the o/s has been patched and tested, we shutdown the 'running' host and bring up the cloned vm and mount the storage and ORACLE_HOME.  Would this idea work? 

Howdy, Stranger!
