Hi Amir,

OL is completely compatible with RHEL. OL has a newer kernel ("uek" which stands for "unbreakable enterprise kernel") and it has ASM drivers in the kernel. The RPM packages are compatible and it is possible to install any RHEL package to OL. There are issues with OL9, I've had problems installing Oracle 19c. OL8 works fine. OL8 has "uek" kernel 5.4, which is pretty recent. There are no differences whatsoever. Also, you can buy support for OL and you can buy on-line patching, just as with RHEL. OL is a good distribution. Interestingly enough, it also exists for ARM64 architecture. Unfortunately, Oracle RDBMS does not exist for ARM64 architecture.
