Happy Thanksgiving to everyone in the US! And happy belated thanksgiving to everyone in Canada since you celebrated back at the beginning of October. :) I’ve been doing a lot of scripting work lately. Although I can’t write about everything I’m doing, I would like to post a pattern that I thought could be useful [...]

Oracle Fully Automated Install and Patch
October 22nd, 2008 § 12 Responses
Before I started consulting, I was an Oracle engineer in a very large software development organization. The company had a number of major products and the one I worked with was used by hospitals and radiology offices world-wide. (These guys are one of the biggest companies worldwide in the field.) Our product included the hardware [...]
ASMLIB Performance vs Udev
October 8th, 2008 § 8 Responses
Is asmlib obsolete on a modern Linux system? I’m still undecided but starting to lean toward “yes”.

About a month ago I wrote an overview of Linux Caching and I/O Queues as they pertain to Oracle. I was working on a project to architect, install and configure the beginnings of an 8-node cluster consisting of either one or two RAC databases. During the project, while I was waiting for the OS guys [...]
Oracle Clusterware on RHEL5/OEL5 with udev and multipath
February 13th, 2008 § 35 Responses
The trouble with Linux? No… the trouble with computers in general – is that they keep changing! Solaris 10 comes out, Oracle 11g, Red Hat 5… and everything works different!! It’s a full-time job just trying to keep up with everything. Almost exactly one year ago I wrote about using udev on 2.6 kernels to [...]
