New Articles on Old Themes Inspired by Work…

I’ve put a couple of new posts live recently that are on quite old themes.

The instance caging article was my feedback to some people at work about one method for managing resources in a consolidated environment.

UltraEdit 3.3 for Mac/Linux…

I’m now rockin’ UltraEdit 3.3 on my MacBook Pro and Linux boxes at home. A previous announcement suggested by this version the Mac and Linux versions would have caught up with the Windows version from a functionality perspective. I’m not sure if that’s true, but they are close enough for me.

The latest Windows versions is 18.20, which I use at work, but home is where the real magic happens. :)

Cheers

Name that Table’s Column

November 9, 2012 I have not had a lot of time to browse through forums lately, but I noticed an interesting thread in the comp.databases.oracle.server Usenet group.  The OP in the thread was curious why quotes (double quotes) were required around a particular column when referenced in a SQL statement, because specifying quotes around the column […]

How to rename NIC in OEL 6.X

This is a quick note about host cloning and network interface (ethX) renaming.
As I wrote in my last post I have ESX lab now and I create a template of OEL 6.3 with all my settings and I would like use it for adding new VM (including RAC nodes). It is easy but there is one small issue – every time you clone VM network devices are renamed. Well MAC address is unique so it doesn’t surprise me but I would like to keep interface names like eth0, eth1 and eth2 and I got eth0, eth3, eth4 instead. Since OEL 5 (Redhat 5) all device name are generated by udev mechanism so I start my research there.
Well it was easier than I thought – there is a file in "/udev/rules.d" directory called "70-persistent-net.rules".
