Published and Available to be Ordered: A Guide to Db2 Performance for Application Developers

The print version of my new book, A Guide to Db2 Performance for Application Developers, can now be ordered directly from the publisher. (If you want the ebook, it can be ordered from the same link below).

Just click on the book cover below and you can order it right now! The link provides more details on the book as well as options for buying the book.

 



Quick information about the book: The purpose of A Guide to Db2 Performance for Application Developers is to give advice and direction to Db2 application developers and programmers to help you code efficient, well-performing programs. If you write code and access data in a Db2 database, then this book is for you. Read the book and apply the advice it gives and your DBAs will love you!

The book was written based on the latest and greatest versions of Db2 for z/OS and Db2 for LUW... and, yes, the book covers both.

If you buy the book and have any thoughts for me, drop me a comment here on the blog!

What Do You Think of the New Design?

Regular readers should have noticed that the logo and basic design of the blog has been "spiffed" up a bit. I did this because the blog has been around for a long time now... my first post was in October 2005! So it was time for a bit of freshening.

Generally speaking, I think blogs are mostly for conveying information, so perhaps I haven't paid as much attention as should have to the look and feel of this blog. But hopefully I fixed that (at least somewhat) for now.

Also, please note that I have not removed any old content. Everything that was here before stays here, even the posts from over a decade ago. I am a big believer in keeping stuff available... some might call that being a packrat, but I wear that label proudly.




So I tend to err on the side of not removing content... I figure, you should note the date of everything you read on the Internet anyway... right?

Let me know what you think of the new look!

Submit an Abstract to Speak at the IDUG Db2 Tech Conference 2019

Hey Db2 people, have you done something interesting with Db2? Have you worked on a cool application or figured out a nifty way of managing your databases? Do you want to share your experiences, know-how, and best practices with other Db2ers? Have you ever wanted to put together a presentation and deliver it to a bunch of like-minded Db2 folks? 
Well, there is still time to submit a proposal to speak at next year's IDUG Db2 Tech Conference in Charlotte, NC. The Call for Speakers is open until October 19th, so if you are interested in presenting, time is running short!
You will have to put together your thoughts and an outline of what you want to present. Start with the category of your presentation. According to IDUG, some of the most popular are:
    • New Db2 releases: migrating and effective usage
    • Analytics & Business Intelligence
    • New Technologies: Mobile Applications, Cloud, xAAS …
    • Performance, Availability & Security
    • Application Development and Data Modelling
    • Db2 and Packaged Applications (ERP, ...)
    • User Experiences and Best-Practices: what did you achieve with Db2?
    • Db2 and non-standard data types (JSON etc..)
    • DevOps, Automation, Efficiency, Tuning stories
But feel free to submit an abstract on any relevant, technical topic. Oh, and you'll need to put together a short bio, too.
As somebody who has spoken at many IDUG conferences in North America, Europe and Australia, I can tell you that the experience is well worth it. Putting your thoughts together to build a presentation makes you reason things out and perhaps think about them in different ways. And speaking at an event is a great experience. Although you will be educating others as you speak, usually the speaker learns a lot, too. 
If your abstract is selected, you get to attend the conference for free (the conference fee is waived, you or your company only have to pay the hotel and travel expenses). And that means you get all the benefits of attending IDUG including the ability to attend all five days of educational sessions, expert panels, and special interest groups. You also get free reign to visit all the vendors at the Expo hall, where there are usually a lot of goodies and snacks.
So go ahead, submit an abstract... or submit multiple abstracts, there is no limit to how many you can submit. 
And hopefully, I'll see you next year, June 2 thru 6, 2019, in Charlotte at the IDUG Db2 Tech Conference.

State of the Mainframe 2018



Every year BMC Software conducts a survey of mainframe usage that provides a unique insight into the trends, topics, and over outlook for mainframe computing. And every year I look forward to digesting all of the great information it contains. The results were presented in a webinar on September 19th (the date of this post).
This year’s survey contains responses from over 1,100 executives and technical professionals ranging in age from 18 to 65+ years old, and with experience levels of 30+ years to less than a year on the job. People were surveyed across a multitude of industries, company sizes, and geographies. And the consensus is that mainframe is key to the future of digital business.
At a high level, the survey indicates that we are working to scale and modernize the mainframe to support new business. And part of that is embracing DevOps practices in the mainframe environment to optimize application delivery.
With a heritage of more than 50 years of driving mission-critical workloads, the mainframe continues to be a powerful and versatile platform for existing and new workloads. Yes, organizations are embracing the mainframe for the new world of mobile computing, analytics, and digital transformation. And that include modernizing mainframe applications because critical apps continue to grow in size and importance. Modernization efforts range from increased usage of Java to API development and encrypting sensitive data. And 42% say that application modernization is priority.

The mainframe’s strengths are many, as this survey clearly shows. Year after year, mainframe strengths have included high availability, strong security, centralized data serving, and transaction throughput – and those strengths were again highlighted this year. But a new strength this year is that new technology is available on the platform. It is clear that IBM’s hard work to ensure that the mainframe can be used with new technology has succeeded and respondents acknowledge its adoption of new stuff while keeping the heart of the business running.
There are a lot of these types of insights in this report, and you should definitely download the report and read it yourself. But here are a few additional highlights that I want to make sure you do not miss out on reading about:
  • Executives (93% of them) believe in the long-term viability of the mainframe.
  • The mainframe remains as the most important data server at many shops. 51% of survey respondents cite that more than half of their data resides on the mainframe.
  • And most of the primary growth areas are trending up in terms of mainframe growth. Mainframe environments are handling significant increases in the number of databases and transaction volumes as well as an increasing trend in data volume.



And 70% of large companies are forecasting that the mainframe will experience capacity growth over the course of the next 2 years.

Of course, challenges remain. According to the survey the top three challenges are the same as they have been recently: cost control, staffing and skills shortages, and executive perception of the mainframe as a long-term solution. So we, as mainframe proponents need to keep banging the drum to get the word out about our favorite, and still viable, platform for enterprise computing – the mainframe.
So download the survey and read all about the state of the mainframe 2018… because the future of the platform is bright, and it will only get brighter with your knowledge and support.
