DB2 9.5 offers a lot of good reasons to upgrade
- 35% Improvement in DBA Efficiency
DB2 automatically performs time-consuming database administration tasks like memory management and storage allocation.
- Lower Server and License Costs
DB2 needs fewer processors, which means less hardware to purchase. It also means less software to license and maintain.
- Lower Storage Costs
DB2 customers are reporting compression ratios of up to 83%, which means less storage to buy and maintain.
- Easier XML projects
Customers are reporting that XML projects require between 30% and 66% fewer people.
- Peace of Mind
DB2's world class security and audit features ensure that you meet your current needs, as well as your evolving future needs.

If you haven't yet upgraded your skills to DB2 V9, here is some incentive for you:
Can you believe that it is already late in March! I've just returned from vacationing with my son for his March break from school... and am refreshed from the vacation... and pumped because SPRING is here!
There are several deadlines approaching quickly that you must take action on to avoid missing important opportunities.
- DB2 Chat with the Labs session featuring a panel of DB2 experts who will discuss cloud computing. Listen live on March 25, 2009 10:00 am PDT/1:30 pm EDT.
Cloud Computing and Virtualization have been named the top 2 strategic technology trends for 2009 by various analysts. With the current climate of tight IT budgets and restraints on capital expenditure, Clouds can come to the rescue with pay-as-you-use models for compute, storage and software resources, and offer flexibility to scale-on-demand. You can now lower the costs of your database solutions by taking advantage of Cloud computing with DB2.
A replay of this and prior DB2 Chat with the Labs are available for approximately one year.

Today I "met" fellow blogger Steffan Surdek
. I encourage you to check out his blog
. Steffan is the User Experience Lead and self-proclaimed Agile Champion for the WebSphere® Business Services Fabric team. He uses his experience facilitating the two-day Software Group Agile Workshops to help his team work on improving their agile processes.
Steffan has written articles that are published on developerWorks and is currently attempting to write a book about Distributed Scrum. This is something that I know very little about, so I had to look it up in wikipedia: Scrum (development)
. His blog provides his experience as a first time author as well as his thoughts about his area of expertise.
For those of you who do know something (or want to know something)about Agile software development, check out Steffan's latest article: Agile planning in real life: What did and didn't work in developing releases with agile planning
It was nice to chat with Steffan today and I hope that you have a chance to check out his blog
One of the publishers that I work with quite often is MC Press
. You may know of MC Press through the large number of books that they have published on IBM products and technologies. For instance, you'll find books within the following categories:
I've blogged many times about the amazing series of certification guides that have been published by MC Press, including:
We're working on two more certification guides that will be part of this series.... so stay tuned to find out more details.
When you go to the book links above... you'll notice that there is a banner on the site reminding you of our Assess & Save Promotion
. Remember that this promotion is only active till the end of the month, so don't miss out.
Two more things you should know.... One... you can save 20% on all books
that you purchase before April 19, 2009
through the MC Press Online bookstore.
Two... if you are a registered member of MC Press Online
, you'll have access to a rich collection of resources such as white papers, articles, and podcasts. MC Press Online likes to reward its members with cool prizes. Currently you have a chance to win a pair of Zetronix 80” Video Glasses
. Interested? Check out the free resources and enter for your chance to win
I have a question for you.... before you buy something these days... do you do what I do and check for online feedback or referrals? If the feedback from someone with actual experience is positive, I am more likely to seriously consider buying the item myself.
If the feedback is overwhelmingly positive from many people, my buying decision gets easier. If the feedback is negative, it helps as well... but only if a clear description of the problem is described and multiple people have experienced the same problem / dissatisfaction.So... will you be willing to provide feedback to others regarding the books that you've read?
Let's face it, making a decision to buy a book isn't only made based on the price of the book, but also on whether it is worth your valuable time to read the book. We're all short on time, so we want to be sure that we aren't wasting our time by reading a book that won't help us.Where can you post your feedback?
For books, amazon.com is likely the most useful place. I'm in Canada, but still chose to read the feedback that is posted on amazon.com rather than one of the Canadian sites. Why? Simply because there tends to be much more feedback on amazon.com than anywhere else.
But, you can still provide feedback on any of the sites that take feedback. Even db2inbooks
is a good site to post feedback.What should you avoid?
It won't help anyone if your feedback is negative, but you haven't actually read the book. Yes, it does happen. For instance, my first book had a negative comment made by a reader because of the title. I don't think the reader read a single word of the book, but decided to trash it based on the title alone. Is this fair? Absolutely not. I'm sure most people would disregard this type of feedback, but save yourself some time, if you didn't actually read the book, don't bother posting comments... positive or negative.
This is actual feedback that I've personally received from a reader who read one of Roger Sander's books.
If you find errors in the book that aren't very serious but that should be corrected.... I suggest that you contact the author directly if you can. It is near impossible to produce an error-free book. Most of the authors who I work with make it easy for you to reach them. Check in the front of the book... you may find an email address. Also check on ChannelDB2.com
as many of our authors are members and would be happy to hear from you.
If you'd rather not contact the author directly... you can always go directly to the publisher... or to me. I'll make sure your comments are sent to the author who can then make the corrections for future iterations of the book.
If you really like reviewing books... and think that you are good at it.... did you know that you may qualify to get free books from the publisher? In some cases we ask people to review the book before it publishes and ask reviewers to provide a comment that may be included on the cover of the book. If this interests you, let me know.
Share your opinion... everyone will appreciate it :)

- Powering SOA Solutions with IMS
New application development tools and the IBM® service-oriented architecture capabilities for IMS™ can help your business improve the speed and agility of its development efforts. Both IMS and the IMS SOA Integration Suite support your on demand systems and your distributed IMS application environment.
Powering SOA Solutions with IMS provides background and explanations to clarify the choices and methodologies that are available to modernize your IMS applications and provide access to IMS data stores through non-traditional callers.
- Embedding Informix Dynamic Server: An Introduction
In this IBM Redbooks publication we discuss and describe the capabilities for embedding IDS into applications and software. We introduce the technological architecture, and describe several of the functions and features that support IDS as a robust and powerful embeddable DBMS. Many of these features are unique in the industry today, enabling clients to create a business advantage.
The Informix Dynamic Server can support the requirements of an embeddable DBMS, and is doing so for many companies today. The low administration requirements of IDS enable clients to deploy thousands of IDS instances, embedded in applications in locations where there are no technical resources to support the database. The real requirement is for applications with embedded databases that require little or no administration, take minimum storage resources, have excellent performance, and are highly reliable.
As a mature and reliable DBMS, it works well with small, growing, and large databases, and meets the key requirements for embedded databases. These include the ability to execute without the need for any configuration or other DBA administrative activities, and the flexibility to work on all of the platforms commonly used in the marketplace today.
- DB2 9 for z/OS: Packages Revisited
DB2® packages were introduced with DB2 V2.3 in 1993. During the 15 years that have elapsed, a lot has changed. In particular, there is a more widespread use of distributed computing, Java™ language, new tools, and upgrades in the platform software and hardware. The best practices back then just might not be optimal today. In this IBM® Redbooks® publication, we take a fresh look at bringing packages into the 21st century.
We begin with an overview of packages and explain the advantages of using packages.
Because database request module (DBRM) based plans have been deprecated in DB2 9, you need to convert to packages if you did not use packages already. We provide guidance on using a DB2 provided function to convert from DBRM-based plans to packages.
We re-examine the application development frameworks for packages: program preparation, package setup, and execution. For distributed applications, we include a discussion of a utility to identify and remove deprecated private protocol and converting to DRDA® as well as an introduction to the new pureQuery function of Data Studio. We also discuss common problems and their resolutions.
We then explore administration and operational activities dealing with packages, including security, access path management (where we discuss the newly introduced package stability feature to allow for a seamless fallback), and management and performance aspects.
The appendixes include useful queries and mention tools for managing packages effectively.
I just found out that the US tax deadline is today. In Canada we have another 2 weeks. I'm getting a refund, so I should have filed sooner than I did... but I had to wait for receipts. What can you do?
I was on a call this morning and someone asked if I was planning to buy a Kindle 2 with my refund. I would love to have a Kindle... and would have bought one... except they aren't available outside of the US at this time. Something to do with the limitations of the wireless connection to the mother ship... I think. In any case, I'll wait... and if some other cool book reader comes available in Canada before Kindle 2 (like Plastic Logic or Apple tablet) then perhaps I'll check that out.
But if you are in the US and like to read... I hear that the Kindle is well worth the investment! All IBM Press books are available in Kindle format as are most books these days. If you prefer printed books, we have plenty for you to choose from. Just yesterday I recommended DB2 books to a VERY technical professor. Here was my response:
Here are the books that I suggest... with reasons why. Click the link to see my blog entries about the books.DB2 9 for Linux, UNIX, and Windows: DBA Guide, Reference, and Exam Prep (6th Edition) See my previous blog entry.Expert Preparation for Exam 734 - DB2 9 for Linux, UNIX, and Windows Advanced Database Administration Certification Study GuideSee my previous blog entry.Understanding DB2(R): Learning Visually with Examples (2nd Edition)
The book is the best way to learn (or relearn) DB2 for Linux, Unix and Windows. The book is filled with case studies, study questions, and well-written details on everything you'll need to know. Some competitively trained people who have read this book have told me that this is exactly what they needed to take the fear out of switching to DB2! See my previous blog entries.
~~~~~~~~~~~~~~~~If this professor is a member of the Academic Initiative
, he should check that out as well. If he will be using the book to build a curriculum around, choose the third one.
Make an author / bookseller / publisher happy.... and buy a book :)
