    Quick post to bring the Virtual Box PDF to the attendees. Follow this link to get the instructions RAC Attack Using VirtualBox UPDATE This post was the best way to get the PDF instructions to participants of the OUGN 2012 RAC Attack seminar without too much effort on our side. If you have since then…

  • No more excuse not to use large pages in Linux

    This is a very quick post to remind users of the importance of large pages. Before 11.2.0.2 it was a little more elaborate process to determine the number of large pages to be set aside for Oracle, but now it’s so simple there isn’t any more excuse not to use large pages. If you have…

  • AIM SIG and my talk about Enterprise Manager 12c

    Yesterday I presented at UKOUG’s Availability, Infrastructure and Management Special Interest Group (hey, say this 3 times in a row, quickly!) about Oracle Enterprise Manager 12c and my experience with it. As my good fried Piet de Visser pointed out I had way too much to say for the 45 minute slot allocated. But then…

  • Availability Infrastructure & Management SIG March 14th 2012

    I am proud to be able to speak at the first instalment of the Availability, infrastructure and management SIG on March 14th in  the London City office. The event is announced on the UKOUG website here: http://www.ukoug.org/events/ukoug-availability-infrastructure-and-management-sig-meeting/ Unfortunately I will be between you and lunch! I hope that works out, and I don’t overrun. I am going…

  • 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…
