  • Nice surprise-automatic statistics email

    Today I got a nice surprise email from WordPress. Seems like my blog wasn’t doing too badly last year. I would like to thank all visitors for passing by and reading my ramblings about this and that-mainly Oracle related. Have a happy New Year all!

  • Adding user equivalence for RAC the easy way

    This is the first time I am setting up a new 11.2.0.2 cluster with the automatic SSH setup. Until now, I ensured user equivalence by copying ssh RSA and DSA manually to all cluster nodes. For two nodes that’s not too bad, but recently someone asked a question around a 28 (!) node cluster on…

  • 5 out of 5 for Pro Oracle Database 11g RAC on Linux!

    For a long time I didn’t dare look at Amazon reviews for “Pro Oracle Database 11g RAC on Linux”, the book Steve Shaw and I worked on for the greatest part of the last 18 months. Well I actually joined him in March this year to be fair. So now Steve sent me an email…

  • Logica Guru4Pro – Amstelveen

    Yesterday I returned from a trip to Amsterdam where I presented about Grid Infrastructure 11.2 as part of Logica’s Guru 4 Pro series. I have to say it has been a very pleasant experience! And it marked the first time I presented outside the UK as well. Logica Holland runs a series of events where…

  • Configuration device mapper multipath on OEL5 update 5

    I have always wondered how to configure the device mapper multipath package for a Linux system. I knew how to do it in principle, but was never involved in the configuration from start up. Today I got the chance to work on this. The system is used for a lab test and not a production…

  • Installing RAC 11.2.0.2 on Solaris 10/09 x64

    One of the major adventures this time of the year involves installing RAC 11.2.0.2 on Solaris 10 10/09 x86-64. The system setup included EMC Power Path 5.3 as the multipathing solution to shared storage. I initially asked for 4 BL685 G6 with 24 cores, but in the end “only” got two-still plenty of resources to…

  • Build your own stretch cluster part V

    This post is about the installation of Grid Infrastructure, and where it’s really getting exciting: the 3rd NFS voting disk is going to be presented and I am going to show you how simple it is to add it into the disk group chosen for OCR and voting disks. Let’s start with the installation of…

  • Kindle version of Pro Oracle Database 11g RAC on Linux

    I had a few questions from readers whether or not there was going to be a kindle version of Pro Oracle Database 11g RAC on Linux. The good news for those waiting is: yes! But it might take a couple of weeks for it to be released. I checked with Jonathan Gennick who expertly oversaw…
