DB2 LUW Performance: Full Day Ed Seminar at IDUG AP - Instructions

IDUG AP 2010 Logo

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,

DB2 LUW Performance: Help! Your chance to improve DB2 in just 15 seconds!

Dear DB2 LUW Professionals,

We need your help to improve DB2 LUW. 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.

DB2 LUW Performance: IDUG Ed Seminar Z06 Preparation Instructions

Dear DB2 LUW Professional,

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.

IDUG NA 2010 Conference Logo, Click for Details

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
All of the SQL commands provided to you during the class will reference the schema name IDUGCONF. The rest of this blog post contains the specific commands that you can use to prepare for the class. When you return back to your office with electronic copies of the SQL Snapshots, all you will need to do is change IDUGCONF to SYSIBMADM and you'll be ready to analyze your databases locally!

This should be a $5,000 course. IDUG is making Ed Seminars available "for a song" relatively speaking - only $425 with a conference badge or just $475 for the seminar alone. Click the IDUG logo above to register now! Early registration ends 26 March 2010.

DB2 LUW Performance: Scalability, Availability, and Disaster Recovery

IBM is generating a lot of buzz with DB2 pureScale, and there is plenty of press to read on Database and Hardware wars. The DB2Night Show™ Episode #4 featured special guests from the IBM Toronto Lab who gave us an outstanding introduction to DB2 pureScale - catch the WMV replay if you missed it. On the heels of DB2 9.7 Oracle enablement, DB2 pureScale is an exciting response to Oracle RAC. But is pureScale right for your organization, or should you be considering Xkoto GRIDSCALE instead? First and foremost, IBM DB2 PureScale is NOT a Disaster Recovery solution, but Xkoto GRIDSCALE is. How else are these technologies different?

DB2 LUW Performance: I/O Optimization and Solid State Disk (SSD)

IBM Data Management Magazine Q1 2010 arrived today and I was excited to find an article on Unleashing the value of Solid State Drives. Of course, I was thrilled to see DBI's new ad as well (grin). The article puts forth several good ideas about I/O tuning and begs for greater details. Whether you have SSD or not, the principle ideas of the article still apply to "faster storage" versus "slower storage". Let's take a deeper look...

Orickle Announces 13G - Promises DB3 LUW Enablement

In the wake of recent claims by Larry E, I'm joining Craig Mullins and re-cycling a former blog post with updates...

29 Jan, 2010 - Redrock Shores, CA. In late breaking news today, Orickle announced preliminary plans for the next version of its world dominating database 13G. Version 13G will include new features such as DB3 LUW Enablement and nano compression. A senior Orickle executive who requested anonymity said "We skipped 12 because 13 is a lucky number, and 'G' now stands for Global domination. We lost some serious market share to DB3 9.7 but we believe we can win global database dominance back with our superior marketing, sales, and negotiation tactics." Continued...

IBM announces DB2 for LUW 9.8 featuring "pureScale"

We heard it hear first - live from IDUG Europe in Rome Italy! In the wake of Orickle's 13G announcement, clearly IBM has its boxing gloves on!

DB2 LUW pureScale is somewhat akin to DB2 z/OS sysplex data sharing - multiple "member" hosts share storage and are interconnected by a high speed switch, although, in DB2 LUW's case, the switch is facilitated by innovative software running on a robust Power series server. The architecture and scalability is ideal for organization's having extremely high OLTP transaction processing requirements. More...

DB2 LUW Performance: Clustering Indexes

We just completed our Webinar on DB2 LUW Index Design Best Practices and Case Studies. Clustering Indexes were discussed, and one of the Webinar participants sent an email asking this question:

Great webinar today, thank you. A quick question on clustering indexes. When trying to determine the best columns by looking at the highest aggregate sort time, what should one do if there is already a cluster index on the table? That is, what to do if the existing cluster index is suspected to not be the right one? Here's my answer...

DB2 LUW Index Design Best Practices

Despite all the hype about AUTOMATIC tuning, a remarkably large number of DB2 LUW customers are still suffering from inadequate and sub-optimal performance. AUTOMATIC tuning can provide some benefits, BUT it only works well when the database is free of significant physical design defects.

We have heard from DB2 LUW users that their ETLs take too long. Index changes were the solution.

We have heard that response times were too slow. Index changes were the solution.

We have heard that CPU utilization is too high, or that there are periodic spikes in CPU utilization. Index changes were the solution.

We have seen OLTP applications appear to "seize up" or "stall". Index changes were the solution.

We have seen DB2 users struggle to complete year end and quarter end reports on a timely basis. Again, Index changes were the solution...

DB2 LUW Health and Fitness Monitoring

I pushed my father in a wheel chair for the first time last month. As I looked at the man who was my Scout Master, who helped me achieve Eagle rank, who taught me to bowl, and inspired me with strong core values of helpfulness and community service, these wheel chair excursions marked a pivotal inspiration point for contemplating my own current health, and have given rise to my own self-improvement goals that you can read about in my personal blog. This year's new IDUG presentations and Ed Seminars will also include new information on DB2 Health monitoring. So, in this blog post, let's look into the health and fitness of your databases.

DB2 LUW Performance: A Self Tuning Memory Manager Case Study

I was recently contacted by a DBA at a large insurance company. After upgrading from DB2 V8.2 to, the DBA activated the Self Tuning Memory Manager (STMM) in the hope that it would solve all performance woes. To the contrary, performance got worse, and the DBA noted a marked increase in SORT overflows. He even opened a PMR with IBM. But this isn't a case of STMM gone crazy; something else is going on, but what? Let's take a look at the numbers and discover the truth.
