Are you attending IDUG AP in Sydney? I hope so! The hard working volunteers at IDUG asked me to repeat my extremely successful and popular Ed Seminar from North America 2010 - "DB2 LUW Performance Analysis and Tuning Workshop".

To obtain maximum value from this class, you should follow the preparation instructions from THIS EARLIER BLOG POST (Click Here).

If you are not attending IDUG AP Sydney, don't worry - you have another chance at IDUG EMEA in Vienna Austria! This class is worth the trip! You will be receiving over thirty six (36) SQL Snapshot commands that will help you analyze and tune your DB2 LUW databases!

Finally, please don't plan on leaving early if you can avoid it. At IDUG North America, there were so many good questions and so much lively discussion that we actually ran long by a couple of hours. After class, we'll find the nearest pub and have a graduation ceremony to celebrate your success.

See you at IDUG,
Cheers,
Scott]]> http://www.dbisoftware.com/blog/db2_performance.php?id=210 Tue, 24 Aug 2010 19:31:30 +0000 DB2 News http://www.dbisoftware.com/blog/db2_performance.php?id=210#cmt The DB2Night Show™ hosted special guest Mark Wilding, IBM STSM & DB2 Cloud Architect, in episode #26, and replays are available for your enjoyment and education!.

I'd like this Seminar to be the best attended Ed Seminar of the conference, and I've heard that Z06 is in the #2 position.

As we like to say in Texas, let me shoot you straight. I'm going to make you an unprecedented offer and guarantee. If you attend this Ed Seminar, and if, by the end of the class, you can't (in good faith) give the class a four or five star review, I'll buy a copy of Roger Sanders DB2 LUW certification book for you. Shoot, I might even give away a couple of copies as prizes.

We just ran Episode #16 of The DB2Night Show™ with special guest Adam Storm, Software Developer, DB2 Kernel Development, IBM Toronto Lab. We talked about Autonomic Memory and STMM updates. Watch the Replay. The studio audience asked a few good questions, but a vigorous email discussion ensued after the show.

Long story short, STMM is either "ON" for a parameter or "OFF". It has a VERY LONG LEASH to grow and shrink memory pools. There are some people in the DB2 LUW community that have experienced performance degradation or problems with STMM (about 20 percent in our audience survey), and a number of professionals would be more interested in using STMM if it were possible to give STMM "a short leash" - that is, for each memory pool under STMM's control, be able to specify a minimum and maximum value range. By specifying a range, one could keep STMM from making a pool too small or excessively large.

Adam told us that ranges had been considered, but were dismissed in favor of ON/OFF (I guess that was easier to implement). He also told us that range limits for STMM could be implemented if there was enough interest within the DB2 LUW community in favor of range specification capability.

Here's where you can help. We've made it really easy. Just click this MAILTO:ibmdb2stmm.developers@dbisoftware.com?subject=I support STMM Min Max Value Ranges link, add some text to the body of your message (optional), then click your SEND button.

We had a very special guest on the show - Adam Storm, Software Developer, DB2 Kernel Development, IBM Toronto Lab. Adam gave our virtual studio audience a great presentation on recent updates to DB2 LUW Autonomic Memory and the Self Tuning Memory Manager (STMM). His slide deck was insightful, information packed, and very informative.

Check out replays of this and prior episodes at http://www.DBISoftware.com/blog/db2nightshow.php.

While we're at it, I should bring your attention to these upcoming episodes:

• 30 April 2010, "DB2 LUW Performance Updates and Best Practices" with the one, the only, the infamous Berni Schiefer, IBM Toronto
• 7 May 2010, "Top 10 DB2 LUW Mistakes that people make" with special guest Klaas Brant, IBM DB2 GOLD Consultant, Owner KBCE, The Netherlands (Klaas' Dutch is excellent, and so is his English).

And, one last thing for today - did you see the freely available SQL Snapshot command that analyzes memory for a database located here?]]> http://www.dbisoftware.com/blog/db2_performance.php?id=194 Fri, 09 Apr 2010 13:23:18 +0000 DB2 News http://www.dbisoftware.com/blog/db2_performance.php?id=194#cmt the recorded replay. This show also set a new record for lively and excellent questions from the virtual studio audience - so be sure to listen through to the end to gain extra insights!

With this particular episode, we've also broken precedent and made Ergin's slide deck available as a PDF. He provided excellent examples of how to use DB2 ADMIN_TABLE_MOVE during his talk. You'll find the PDF link on the show replay page.

Have you registered for IDUG North America in Tampa Florida yet? There are still a few good seats left in my full day seminar Z06: DB2 for LUW Performance Analysis and Tuning Workshop. Attendees will receive over three dozen amazingly helpful SQL Snapshot commands (see a sample and learn more) ... ]]> http://www.dbisoftware.com/blog/db2_performance.php?id=192 Tue, 06 Apr 2010 17:55:23 +0000 DB2 Performance Best Practices http://www.dbisoftware.com/blog/db2_performance.php?id=192#cmt I invite and encourage you to attend my Education Seminar, Z06: DB2 for LUW Performance Analysis and Tuning Workshop, at IDUG NA 2010 in Tampa Florida. Without exception, I've never before put so much effort into preparing a full day seminar. In this class, you will receive over three dozen SQL Snapshot commands to help analyze YOUR database. Together, we will learn about what to measure, we will discover the problems and "opportunities for improvement" in your database, we will discuss solutions, and you will return to your office fully equipped to make measurable performance improvements.

In terms of preparation for this class, here's what you will want to do to optimally prepare:

1. Make copy tables of SYSIBMADM snapshot views and some catalog tables (CREATE LIKE)
2. INSERT INTO copy table SELECT * FROM original table or view
3. EXPORT TO IXF file SELECT * FROM copy tables
4. Binary transfer the IXF files to a laptop running DB2 LUW (Express-C (free DB2) will suffice)
5. IMPORT FROM IXF file REPLACE_CREATE INTO local copy of tables on laptop

This should be a $5,000 course.
