    DBAs love using DSN1COPY because it quickly copies files from one system to another. You just need to be careful about how to use it. Test out the process and make sure you understand the impact database changes have on your test system and production systems.

    Why You Should Move to Universal Table Space

    Almost six years ago, I wrote that the future for all DB2 data storage on z/OS will be Universal Table Space (UTS). The purpose of this post isn't to pat myself on the back, but to note that the future is here.

    Spark Takes Data Analysis to the Next Level

    I must admit that, until very recently, I'd never heard of Spark. But since it was such a big deal at this spring's IDUG NA conference --  an entire day was devoted to it -- I figured I should take some time and learn about it.

    RESTful APIs Unlock the Value of z/OS Assets

    If you work on the mainframe using z/OS and haven't heard of RESTful APIs, you need to wake up and smell the coffee. Seriously, even though RESTful APIs are still a fairly new thing, they're already essential. If you don't know about them, ask the people on the distributed side of your business -- who I can assure you already rely upon them -- to help bring you up to speed.

    Really, We're All Experts Here

    Since joining IBM last year I've been spending more time speaking to user groups. This got me thinking about a post I wrote back in December 2012 on the professional benefits of public speaking. While I'd love for you to read the whole thing, I'll sum it up in four words: You can do this.

    developerWorks Community for DB2 Analytics Accelerator

    Last year I noted that IBM was accelerating development of the DB2 Analytics Accelerator. With new maintenance releases coming out about every 3-6 months, it's a challenge to keep up with all the changes.
