  • Getting started with iSCSI part I-Openfiler Fundamentals

    After having read a number of articles detailing the use of Openfiler and Real Application Clusters I was intrigued, especially by the prospect to set up my own extended distance cluster.

    UPDATE 221103: Oracle 11.2 is effectively out of support, this article is now archived and should not be referred to After having experimented with my 11.2.0.1 Clusterware setup in the lab, I thought it was time to put the promise of easy extensibility to the test and run addNode.sh to extend the cluster to two…

  • Archivelog retention policy changes in RMAN 11g

    UPDATE 221103: Oracle 11.2 is effectively out of support, this article is now archived and should not be referred to In the past, that means at least until 10.2.x it used to be a bit clumsy to set the archivelog deletion policy to “applied on standby” on both primary and standby database. It involved setting…

This is the third part of my “build your own RAC” article series, and this time we are about to install and discuss Grid Infrastructure.

  • Build your own 11.2 RAC system-part II: DNS & DHCP for GNS

    UPDATE 221103: Oracle 11.2 is effectively out of support, this article is now archived and shouldn’t be referred to. Wow, I managed to cram 4 acronyms into the subject line, not bad for a Friday! The reason of this post is simple: I want to get Grid Naming Service (GNS) up and running on my…

  • Build your own 11.2 RAC system-part I: DNS

  • RAC SIG 09/2009

    The last RAC SIG meeting before the conference, in an Oracle building in Solihull near Birmingham. I was really delighted to see some of my friends after some time, and David had a great agenda for the day. Phil Davis’s deputy gave a refreshingly open service update, the main highlights were: 11.1.0.7 is the terminal…

  • UNIX SIG 09/2009

    I can’t say I like junction 15 a lot … simply too much traffic when moving off the M25. When arriving at the venue I was still quite early and had a chance to catch up with Phil Davis and Joel Goodman from Oracle. It seems that the credit crunch affected the numbers quite badly…
