Alex Gorbachev at ACTOUG Developer and DBA Seminar Day

I’ll be in Canberra next week presenting at the ACT Oracle User Group Developer and DBA Seminar Day on Thursday, 23 July 2009. If you are in Australian capital city, I’d be very much looking forward to see you there! The topic I will be presenting is 11g New Features Out of the Box. I presented it few times already but originally, it’s based on Christo Kutrovsky’s presentation from Oracle Open World 2007. Unlike many presentations on 11g new features, this session will be focused on the enhancements that often go unnoticed and not marketed widely but boost DBA productivity and are available out of the box without much implementations efforts.

Sydney Oracle Meetup #8 — Exadata Extravaganza

The topic for this meetup is quite exciting – Oracle Exadata and everything about it. David Centellas, Senior Database Consultant from Oracle will do technical presentation on Exadata and, after the break, we will have a open forum discussion where two Oracle’s Enterprise Architects, Tim Rubin and Chris Jones, will answer our questions and share thir real-world experience.

Database Analyst Steals Credit Card Data

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.

Connecting to Oracle with SQL Server 2005 x64

Using OLE DB to get SQL Server to connect to Oracle servers can be done quite easily, but there are a few little tricks you should know to make it go smoothly. Once it’s working it seems to work quite well. I hope this blog post will save you a few headaches.

Oracle 11g SE Switch-Over

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.

Scalable Internet Architectures

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.
