Xen problems with OpenSuSE 12.1 and Intel core-i7
I have set up my new lab server yesterday, which in essence is a rack mounted server with a core i7 2600 processor, 32GB RAM and 3 TB of (slow) disk. When I moved some of my VMs across from an identical system (except that it was a core i7 920) and tried to start…

Oracle 11.2.0.3 client not relinking properly
One of the tasks I am performing quite regularly is to deploy Oracle software in form of an RPM. In a previous post I described how this proces could work, based on a post by Frits Hoogland. Employing the same method, I ran into problems with Oracle 11.2.0.x clients. A few facts to start with:…

Did you know the cluvfy healthcheck?
While I was performing a three day seminar recently in Switzerland I came across this new option in cluvfy. Normally you’d run cluvfy in preparation of the installation of Grid Infrastructure or a set of RAC binaries to ensure everything is ready for the next step in the RAC install process. Beginning with 11.2.0.3, there…

RAC One Node on Oracle Enterprise Manager 12c
One of the promises from Oracle for OEM 12c was improved support for Oracle RAC One Node. I have spent quite a bit of time researching RON, and wrote a little article in 2 parts about it which you can find here: http://www.oracle.com/technetwork/articles/oem/raconenode-dataguard-435121.html http://www.oracle.com/technetwork/articles/oem/raconenode-dataguard-2-435128.html One of my complaints with it was the limited support in…

Beware of ACFS when upgrading to 11.2.0.3
This post is about a potential pitfall when migrating from 11.2.0.x to the next point release. I stumbled over problem this one on a two node cluster. The operating system is Oracle Linux 5.5 running 11.2.0.2.3 and I wanted to go to 11.2.0.3.0. As you know, Grid Infrastructure upgrades are out-of-place, in other words require…

Provision Oracle RDBMS software via RPM
I have always asked myself why Oracle doesn’t package their software as an RPM-surely such a large organisation has the resources to do so! Well the short answer is they don’t give you an RPM, except for the XE version of the database which prompted me to do it myself. The big problem anyone faces…

Getting started with FusionIO
I have been lucky enough to do some work with Fusion IO cards in a blade server, soon to be followed by another set of tests on a full rack mounted server. I didn’t know exactly where model I was given, but powered my server down in eager anticipation of the events to come. After…

The cause for and against the Exadata simulator
I am on my way back from the best UKOUG conference I ever attended, unfortunately a lot earlier than planned. Before I start forgetting all these great moments it is time to write them up. To make use of James Morle’s words: if you weren’t there, you lose. I couldn’t agree more! The Oak Table…

Getting started with Xen virtualisation on Ubuntu 11.10
After a long time and lots of problems I decided to abandon openSuSE 11.4 and its xen implementation in favour of the PVOPS kernel and a different distribution. It’s been difficult to choose the correct one for me, for now I’m working with Ubuntu 11.10. One reason is that it’s said to be user friendly,…

Installing OEM 12c agents in RPM format
One of the questions I have always asked myself revolved around: “why doesn’t Oracle package certain software as an RPM on Linux?” Well this question has recently been answered in the form of the Oracle 12c agent. It IS possible to use an RPM based installation, although it doesn’t make 100 use of RPM. I…
