Operating Systems Linux Red Hat How to switch back from Oracle Kernel to RedHat? Post 303022819 by Neo on Saturday 8th of September 2018 12:52:44 AM
Old 09-08-2018
In the future, I recommend you do these kind of serious database upgrades on a development server first:

Code:
installing "oracle-database-server-12cR2-preinstall-1.0-3.el7.x86_64.rpm"

Now that you have done this without a backup, you have a problem.

Is that server now in production and giving errors?

Or it is not working at all, and your upgrade has killed it?

What is the core problem?
