Oracle Ksplice and Oracle Linux reminder

By: Wim Coekaerts | SVP

For those of you that keep up with my blog and twitter musings... you know how much I love Ksplice. This morning I was connecting to one of my cloud VMs and did an uptrack-upgrade as it had been a while and I hadn't turned on automatic ksplice updates on this node. I was pleasantly reminded of the awesomeness that is Ksplice. 

Here's the output, a kernel from 2-MAR-2018, no reboot, just a quick # uptrack-upgrade and look at all the stuff that I am now protected against. A few seconds, no impact on apps, done. Now I know that there are some other projects out there that talk about being able to patch something here or there. But nothing comes even close to this. Not in terms of service, not in terms of patch complexity, not in terms of easy of use, etc, etc etc.

Remember, everyone using Oracle Linux in Oracle Cloud has full use of ksplice included at no extra cost and no extra configuration, every Oracle Linux instance is configured out of the box to use this. 

No other cloud provider has this service for their OSs. No other OS vendor provides this as a service for their own product at this level of sophistication and certainly not in any cloud environment. Best place to run Linux, best place to run Oracle Linux, all integrated, inclusive ... in Oracle Cloud Infrastructure.. Yes this is/sounds like marketing but.. fact is, it works and it's there.
