The Real Truth About Oracle's 'New' Kernel

An anonymous reader writes "Yesterday at OpenWorld, Oracle announced a 'new' Enterprise kernel for its so-called Unbreakable Linux. What's the real truth? The company is simply sticking a 2.6.32-based kernel on top of its re-branded Red Hat Enterprise Linux clone and trying to spin it as a new and innovative development."

Good for databases

Just one example of why this is good - iotop.

I've been watching the RHEL bug for adding iotop since at least RHEL 5.3. It keeps getting bumped, now RHEL 5.7 IIRC.

It would require a bunch of backporting work from the kernel beyond 2.6.18. But once sysadmins get used to knowing which disks are busy they really get used to that. And doubly so for optimizing database servers.

Redhat's strategy gains them certainty and loses them opportunity. That's certainly a niche that's done well for them, but there are also users with other needs. Oracle's strategy will be very popular with some of them. When Redhat brings RHEL6 to market there will be lots of required subsystem changes to get the new kernel. Some people will just want the new kernel and not want to change all their underlying dependencies, and Oracle is meeting that need. Eventually Fedora will adopt a rolling-release model and RHEL will track that (probably with more QA) but it's a hard problem and not well-solved yet.

It's great that we have such a vibrant market that there's room for so many approaches.
