Hotsos Symposium 2010 — Dallas, I’m Coming!

What should you expect coming to the Hotsos Symposium 2010? It’s 3 days packed with sessions on all aspects of Oracle performance optimization whether it’s design, troubleshooting, development, methodologies and processes. Legendary Tom Kyte — who else can you expect for the keynote?! If you take an optional training day with Tanel Poder then you are likely to learn at least as much about troubleshooting Oracle database performance as you do during the conference and probably even more. Every presentation by Tanel has been an eye opener for me. If you’ve seen his material, you’d know what I’m talking about. Now, imagine that it’s not a one-hour session but the whole day! It will fry your brains so this day is for the strongest! :)

DBD::Oracle 1.24 Released

The “Beer” version of DBD::Oracle (1.24) has been released. You can find it at CPAN DBD::Oracle. DBD::Oracle is a Perl module that works with the DBI module to provide access to Oracle databases. It is maintained by me, John Scoles, under the auspices of Pythian as Open Source/Free Software. This is largely a maintenance release that fixes a number of bugs. New stuff includes some more improvements to embedded types from Charles Jardine. Find out more here.

Let Your Oracle Backups Be Up in the Clouds

There are a lot of discussions going on in the Internet regarding whether we can trust third parties to look after our data. I am not going to add fuel to the fire. I am going to show you how simple it is to backup an Oracle database to the Storage Cloud using the Oracle Secure Backup (OSB) Cloud Module.

Oracle GoldenGate Extract Internals, Part III

This is the third post in Oracle GoldenGate Extract Internals series (links to part I and part II). In this post, we’re going to take a closer look at various queries that the Extract process uses against the database. As before, we will start by examining the strace output.

Easy Pivot Query Result in pre-11g Oracle

I was asked, the other day, to automate the creation of a client’s weekly report, which is a pivot table of some aggregate data generated by a query. I’ve written a set of fairly simple PL/SQL code that handles this task in all versions of Oracle that supports associative nested VARRAYs (I have no clue when that started getting supported. It sure works great with 10g). Here is how my code works.

Pythian Goes to RMOUG Training Days 2010, Denver

I’m so much looking forward to the next conference in my schedule — RMOUG Training Days 2010. It would be only my second time I’m presenting at the RMOUG but it was enough to go there once to understand that it’s one of the top rated Oracle User Group conferences in the world. Some of the great speakers are presenting and registration fees are very low compare to other events of comparable quality. If your conference budget is low this year — that’s the conference you don’t want to miss!

So, You Want to be an Oracle ACE? Oracle OpenWorld 2008 Presentation

In light of the official Oracle acquisition of Sun, I dug out a presentation video I realize I never officially shared with either the MySQL or the Oracle community. It’s the presentation I did at the 2008 Oracle Open World conference called, “So, you want to be an Oracle ACE?” and is a good resource for anyone who wants to contribute to anything — not just Oracle or MySQL, though certainly it’s based on my experiences with contributing to MySQL. Have a look.
