This blog post was inspired by a recent report of a Database Analyst at American Express stealing Credit Card data. It’s amazing how many companies still follow a mainly “perimeter security” approach when it comes to controlling access to sensitive information—their focus is on network security using firewalls, advanced authentication options, and so on. Even with such measures, it’s very common to setup strong barriers to the outside world but very little by way of internal limits; most internal people have some level of access to servers that store and process sensitive data.

Welcome to the 152nd edition of Log Buffer, the weekly review of database blogs.
Recently, I tested a switchover on Oracle 11g SE1. As you know, Oracle Database Standard Edition One—as well as Standard Edition—does not have the Data Guard feature. Therefore, I had to do everything manually. The whole process took less than 15 minutes. This includes less than five minutes of full downtime to restart the database in READ-ONLY mode, and less than 10 minutes of READ-ONLY downtime. Here’s what I had.

My old friend and collaborator Theo Schlossnagle at OmniTI posted his slides from his Scalable Internet Architectures talk at VelocityConf 2009. The slides are brilliant even without seeing Theo talk and I highly recommend the time it takes to flip through them, for anyone who is interested in systems performance. If anyone took an mp3 of this talk I’m dying to hear it, please let me know. Here’s the slide deck. Let me know your thoughts.
Welcome, readers! It’s time for another update to our series of posts on installing Oracle on Ubuntu Linux. In this edition, we’ll be installing Oracle 11g R1 on Ubuntu 9.04, both 32-bit. This time, I’ve used VirtualBox to run a virtual machine (VM) to perform our work.
We will start with an overview of the AQ technology in Oracle database – what it is and what it let you do. Then we will see how it’s used in Oracle E-Business Suite and how to manage it. Our speakers for the evening are your fellow SOM members – Jurijs Velikanovs and Warwick Sands. TBC.
No doubt you want to cast you first vote for my abstract — Developing Plug-ins for Oracle Enterprise Manager by example :) This presentation starts with an introduction of Enterprise Manager’s Extensibility features and walks the audience through the basics of creating a new plug-in. This session will also demonstrate some proven plug-in development steps based on the experience gained from developing MySQL management plug-in. Session includes a demo of the plug-in development scenarios. After this presentation, attendees will be able to design and develop management plug-ins for their own applications. Login to Oracle Mix and vote now. At the time of writing, my session is on the very top — help to keep it there! ;-)
The first videocast was quite popular — it has more than 300 views in couple weeks and considering no Hollywood stars were starring in that video and there were no nude scenes, I think it’s fair to say that this format was very much welcomed by the audience. Today, I’m posting the follow up session on VIP’s (Virtual IP’s) with Oracle RAC. What I demonstrate today is a typical configuration mistake for a RAC databases created with Database Configuration Assistant (DBCA) and what’s the result of such omission.
