Earlier this year (30 March, to be precise) Oracle announced that Oracle Database 11gR2 was available as a fully-supported product for Linux on IBM System z. A while before that they had announced E-Business Suite as available for Linux on System z, but at the time the database behind it had to be 10g. Shortly after 30 … Continue reading Oracle Database 11gR2 on Linux on System z

The next phase in tidying up my user authentication environment in the lab was to enable SSL/TLS on the z/VM LDAP server I use for my Linux authentication (I'll discuss the process on the DeveloperWorks blog, and put a link here). Apart from being the right way to do things, LDAP authentication appears to require SSL or TLS in … Continue reading What a difference a working resolver makes
In 2009 I was part of the team that produced the Redbook "Security for Linux on System z" (find it at http://www.redbooks.ibm.com/abstracts/sg247728.html ). Part of my contribution was a discussion about using the z/VM LDAP Server to provide Linux...
I realised I never came back and reported the results of my OpenSSL "speed" testing after our 2096 got upgraded. For reference, here was the original chart, from when the system was sub-capacity: ... and the...
I had two book-related experiences today, one of which was obvious and prompted this post. The other I had almost forgotten about, but should not have. First, the one I forgot. I went to the shopping centre today (Garden City, in Upper Mt Gravatt) with my seven-year-old son. On the way there we were discussing … Continue reading My local Borders is no more
I made a somewhat cryptic tweet a little while ago about how I spent a crazy-long period of time researching what was, I believed, the next-big-thing in DNS resolution for IPv6 (or so my 2002 edition of "IPv6 Essentials" told me). I could not work out why I saw nothing about A6 records in any … Continue reading Another IPv6 instalment (subtitled: Watch Your Tech Library Currency!)
A little while back I did an "emerge system" on my VPS and didn't think much more about it. First time back to the box today to emerge something else, and was greeted with this: >>> Unpacking source... >>> Unpacking traceroute-2.0.15.tar.gz to /var/tmp/portage/net-analyzer/traceroute-2.0.15/work touch: setting times of `/var/tmp/portage/net-analyzer/traceroute-2.0.15/.unpacked': No such file or directory ...and the … Continue reading Another round of Gentoo fun
Two of the four keynotes at LCA 2011 referenced the depletion of the IPv4 address space (and I reckon if I looked back through the other two I could find some reference in them as well). I think there's a good chance Geoff Huston was lobbying his APNIC colleagues to lodge the "final request" (for … Continue reading IPv6: SSDM?
For some time I've been feeling moody and generally unhappy. My ability to become frustrated with things that go wrong is ever-increasing, and my tolerance fuse seems to be ever-shortening. Co-incident with those feelings was the real physical manifestation of almost constant weariness -- waking up tired, never-ending back and shoulder pain, and so on. … Continue reading Burnt out
On Saturday (a couple of days ago as I type this) I volunteered to assist the cleanup in Brisbane's suburbs -- the city council organised volunteering locations where you could sign up and be transported to places that needed help. The process was well organised, except at the location I went to where the buses … Continue reading My flood volunteering day
