I would like to know how can I switch from Oracle kernel to RHEL kernel without breaking anything.
Since there was no testing previously in an identical testing machine, this box has become the testing one now. No testing, no confidence in anything.
You can test if it doesn't break anything by rebooting and at the grub menu select the red Red Hat Enterprise Linux Server (3.10.0-862.9.1.el7.x86_64) 7.5 (Maipo). If it boots properly, check that if everything is what's expected. If everything is proper then change the entry in the grub.conf that says default=1 to default=2 which is the third kernel menu corresponding to that version of redhat supported kernel.
Perhaps it is easier to issue the command:
That only makes the selection of which kernel to boot from, persistent on reboots and shutdowns.
Depending of the yum configuration there might be issues updating kernels, you might have to set it up to exclude kernels updates in from the oracle repo.
You might want to remove with yum or rpm the title Oracle Linux Server 7.5, with Unbreakable Enterprise Kernel 4.14.35-1818.0.9.el7uek.x86_64 and Oracle Linux Server 7.5, with Linux 3.10.0-862.11.6.el7.x86_64
A lot of testing.
I need some help from Oracle and UNIX expertise point of view.
