I installed this on Kubuntu 10.10 x86_64 systems with the newest Oracle 11.2 client. The version of TOra this time around is 2.1.2 which works fine except for one really really frustrating thing, that I will mention at the end to keep you in suspense. I ran through this 3 times on 3 separate systems (VM, work and home) and in all cases I got through it mostly unharmed with only a few humps. So here we go, it’s time to…

Anyone can fall into this scenario. Everyone is carefully taking time to test before applying a couple patches to address an async I/O issue in Oracle to ensure all testing environments are exact, all patching is approved by everyone that would like to review it.

Suddenly, the database reaches what every DBA dreads…
Oracle has consolidated the diagnostic information of database under one umbrella called as Automatic Diagnostic Repository (ADR). This repository is XML-based and that opens up new vistas for future Oracle diagnostic tools to manipulate the hierarchical data.
In looking at this subject, most of you will say: Hey Yury! What’s new that you can tell us about? The following note describes it all:
11gR2 Grid Infrastructure Does not Use ULIMIT Setting Appropriately [ID 983715.1] These were exactly my thoughts when I was called to troubleshoot a case where a DB instance, starting with the “srvctl start instance” command failed to use Huge Pages in Linux.

Warm welcome to the Log Buffer, a weekly amalgamation of database news across different technologies. Let’s get warmed up with sizzling Log Buffer #213.

App::perlbrew is a tool that simplifies down to triviality the process of making local perl installations. With it, any user can, in the span of a few minutes, have a working perl that is totally independant of whatever the system has.

The path to self-sufficient brewing is incredibly easy. First, you have to download and install perlbrew
Last week brought great news to Pythian – one of our DBAs in Pakistan, Fahd Mirza, has become an Oracle ACE. Fahd joined Pythian in September 2010 as the very first Pythian employee in Pakistan and thanks to his skills and ambitions ended up on the team supporting Exadata environments. I should also mention that another Oracle ACE DBA joined us recently – Jared Still. Jared is a well respected member of Oracle community, member of the OakTable Network and a veteran of the Oracle-L mailing list
