Tools for checking broken web links - part 1

With a growing web site, it becomes almost impossible to manually uncover all broken links. For WordPress blogs, you can install link checking plugins to automate the process. But, these plugins are resource intensive, and some web hosting companies (e.g., WPEngine) ban them outright. Alternatively, you may use web-based link checkers, such as Google Webmaster Tools and W3C.

Your language sucks...

As a result of work I've been doing for illumos, I've recently gotten re-engaged with internationalization, and the support for this in libc and localedef (I am the original author for our localedef.)

I've decided that human languages suck.  Some suck worse than others though, so I thought I'd write up a guide.  You can take this as "your language sucks if...", or perhaps a better view might be "your program sucks if you make assumptions this breaks..."

Oracle VM Server for SPARC Best Practices White Paper

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.

Speeding up kernel crash hang analysis with the kernel log

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

Oracle Linux Containers and docker and the magic of ksplice becomes even more exciting

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.

The magic of ksplice continues...

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.

The magic of ksplice

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.

Oracle ASM vs ZFS on VNX

In my last post on ZFS I shared results of a lab test where ZFS was configured on Solaris x86 and using XtremIO storage. A strange combination maybe but this is what a specific customer asked for.
