It has a few add-ons.
The "Unbreakable Enterprise Kernel" includes full btrfs, extensive device support (that is removed from the stock kernel), is tuned for the eponymous database, and is always more current. There are several scenarios where it is very attractive.
Oracle bought K-Splice several years ago, which was the first rebootless patch solution for Linux. It's only available with a premium license; Kernelcare is a lot cheaper.
Supported Oracle Linux versions are also available for WSL1 inside of Windows.

Oracle Linux came into existence shortly after Red Hat bought JBoss. As Oracle had also bought BEA Weblogic (IIRC), this was not taken well.
- greedo 3y agoOEL is dependent on RHEL for patches, so how can it be "always more current."?
- chasil 3y agoThe UEK is more dedicated to following long-term-release kernels. Oracle's re-wrap is known as the "Red Hat Compatible Kernel." v7-rhck-3.10.0-1160.92.1.0.1 v7-uek-5.4.17-2136.320.7.1 v8-rhck-4.18.0-477.13.1 v8-uek-5.15.0-102.110.5 v9-rhck-5.14.0-284.11.1 v9-uek-5.15.0-102.110.5.1 Kernel version 3.10 has always been stock rhel7's version, but the UEK has jumped through v4 to v5. Red Hat made a big deal about io_uring availability in v9, but I am guessing that it is available in v8's UEK. I will say that the Oracle database group's support for v9 is very poor at this point; for some reason, they are holding to v8, and releasing few products for the newer platform.

There are several scenarios where it is very attractive. I'd never go for btrfs in anything enterprise. But it does annoy me how RHEL moves normal open source software to the separate repos that are available with extra support packages, it just makes managing it annoying
- chasil 3y agoIt also annoys me to great extents when Red Hat removes support for SAS raid cards that are perfectly usable. Oracle fixes that.
- worthless-trash 3y agoRemoved it midstream or between releases ?
- sketch242 3y agoRH generally only removes features in major releases. The exception is when they introduce features as a technology preview. Those are subject to potential removal before the EOL of that major release, though they rarely do.
- worthless-trash 3y agoThat was what I had thought. I'm confused with the original statement being a problem as both vendor and the os both need to support the hardware. If there is a problem with the firmware who will RHEL go to keep its agreements ?
- birdyrooster 3y agoDon't forget OCFS2 as well! I am surprised that HN didn't know OEL wasn't just s/redhat/oracle/
