I'm very pleased to announce a new white paper has been published: Oracle VM Server for SPARC Best Practices.
This paper shows how to configure to meet demanding performance and availability requirements.
This is a summaries article taken from RHEL6: Speeding up kernel crash / hang analysis with the kernel log.
When there is a kernel crash or hang, there is often a very large file is produced containing a memory dump of the entire system called a vmcore. Analysis of the kernel crash or hang often requires this large file be uploaded to Red Hat for analysis (if you have subscription)
For RHEL 6.4 and above
So, in my previous blogs I talked about the value of ksplice for applying updates and keeping your system current. Typical use case has been on physical servers running some application or in a VM running some application and it all keeps every system pretty isolated. Downtime on a single server is often, by a system admin, seen as no big deal, downtime of a bunch of servers because of a multi-tier application that goes down, however, by the application owner is a pretty big deal and can take some scheduling (and cost) to agree on downtime for reboots.
My previous blog talked about some cool use cases of ksplice and I used Oracle Linux 5 as the example. In this blog entry I just wanted to add Oracle Linux 6 to it. For Oracle Linux 6, we go all the way back to the GA date of OL6. 2.6.32-71.el6 build date Wed Dec 15 12:36:54 EST 2010. And we support ksplice online updates from that point on, up to today. The same model, you can be on any Oracle Linux 6 kernel, an errata update, a specific kernel from an update release like 6.1,... 6.5,... and get current with CVEs and critical fixes from then on.
I love talking about Oracle Ksplice and how cool a technology and feature it is. Whenever I explain to customers how much they can do with it, they often just can't believe the capabilities until I show them, in a matter of literally 5 seconds that it actually really -just works-.
During Oracle OpenWorld, we talked about it a lot, of course, and I wanted to show you how far back these ksplice updates can go.

As another writer said, 2014 has been a terrible year for women in tech. (Whether in the industry, or in gaming.) Arguably, this is not a new thing, but rather events are reaching a head. Women (some at any rate) are being more vocal, and awareness of women's issues is up. On the face of it, this should be a good thing.
