2012-05-14 12:41:21.653801 SCRIPT 30 Exit I am looking forward to going to Denver this weekend in preparation of IDUG NA which starts on Monday, May 14. I'm hoping to blog and tweet from there, so regardless if you are at the conference or not, you can follow what's going on. Here are some key links:
IDUG's Facebook page will also be pretty busy during the conference too: www.facebook.com/IDUGDB2
Scott Hayes has set up an aggregator site that includes all of the tweet related to IDUG: http://bit.ly/idugna12
Mike Krafick is the social media guru for IDUG. He tweets from IDUGDB2 and is looking for more followers. He's trying to get more followers than my twitter account susvis. Let the challenge begin!
On Tuesday in the Exhibit Hall, we'll be handing out a limited supply of signed copies of the New Flashbook for DB2 10. For those of you not at the conference, follow my blog for information on how you can download a copy for free.
Two other books will be launching at IDUG this year. We don't have a bookstore, but be sure to speak to the authors for information on ordering a copy for yourself at a discount offered to IDUG attendees:
The winner of this year's DB2's Got Talent competition was Kohli (We HAVE a winner! DB2's Got Talent Competition) and he chose to attend IDUG Denver as his prize. I'm looking forward to meeting Kohli. If you were also a competitor, please find me at the show and introduce yourself.
If you're interested in writing articles or books, or reviewing any of the upcoming books... also find me and let me know. I may have some interesting opportunities for you!

The web is wonderful, but the web is evil! Wonderful because it contains so much content and evil because it contains so much content! It can be overwhelming to navigate through the content and if you don't immediately find what you're looking for, it is very easy to get distracted and forget what you were looking for in the first place.
My intention for this blog entry is to help those who use the DB2 for z/OS products find skills resources that are specific to you. I hope you find this content helpful!
The next generation of IBM Data Management magazine is available for you to read online. It has many great articles, including regular columns by Bonnie Baker and Robert Catterall.
So far, two books have published to support DB2 V10... but there are more coming.

"Flashbooks" are small-sized books that have fewer than 150 pages, and have easy-to-read messages about products, solutions, or technology. Flashbooks are published to coincide with conferences such as IBM's Information on Demand Conference or IDUG. The huge quantity of messages and content delivered at such conferences makes it difficult for attendees to retain all the key messages. Flashbooks are designed to contain the key messages IBM experts want you to take away with you.
Flashbooks are handed out in print format at conferences and other events, are available for free in ebook format from this site and can be purchased from amazon.com or other online bookstores.

I Didn't Know DB2 did THAT!: Bonnie Baker, Bonnie Baker
Corp.
Have you ever wondered what goes on inside DB2 when your SQL is
being executed? This seminar is designed to answer exactly that question and
more by taking a look at DB2 Components and the Optimizer's instructions for
various SQL access paths. While simple paths will be reviewed, this class will
also focus on those difficult to understand access paths. Topics include RIDPOOL
failures, Hybrid Joins and a "Type C" Hybrid Join, coding both a GROUP BY and an
ORDER BY on the same columns to insure that my GROUPs are returned in ORDER,
using a 64-partition DPSI for SORT Avoidance, how does DB2 know if Index-Only
data is "clean" or "dirty", result sets built at OPEN CURSOR, DSNZPARMs affects
on access path selection and operation and much, much more!
Certification for DB2 is the MOST popular certification program in IBM! Not everyone who uses DB2 is IBM Certified yet, but the version 10 exams are available and is a great place for you to jump on board. Here is an offer for getting certified for half price as well as some information on how to started on your path to getting certified:
The DB2 for z/OS community is heavily into blogs. I've had the pleasure to work with Willie Favero and Surekha Parekh on presentations about social media. Here are some of the bloggers you may wish to follow:
My apologies if I missed your blog! Drop me a line and I'll make amends :)
Suggestion... check out who these people are following. That will give you suggestions as to who else you may wish to follow.
Communities are a way for you to participate in conversations with other like minded people. You'll find lots of resources, news about events, and perhaps access to experts.
Yes, there is more. Much more. I didn't even begin to cover the courses offered by IBM Education. I hope what I have provided is helpful and I'll update this page when I have more to add.
