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

    UPDATE 221103: Oracle 11.2 is effectively out of support, this article is now archived and shouldn’t be referred to. As many of you already know, Oracle released 11g Release 2 of the database for Linux x86 and x86-64. That is really cool and this time I don’t want to miss out on researching some new…

  • RAC SIG 09/2009

    The last RAC SIG meeting before the conference, in an Oracle building in Solihull near Birmingham.

  • Presentation Update

    UNIX SIG Slough 09/2009 This is a novelty to me – going to present twice! The first presentation will deal with Linux Kernel settings and how to tune them, the second one deals with OpenFiler 2.3 and iSCSI on Linux. RAC & HA SIG 09/2009 And if that wasn’t enough I am also going to…
