I'll occasionally be throwing in a post covering our z/OS operating system and our System z hardware. Plus, there will always be something entertaining posted every once in a while. This is the place you'll find just about anything you need to know to stay current with DB2 for z/OS, z/OS, or System z.

    Are you using the DB2 Diagnosis Guide and Reference?() There are three questions that follow about the usage of the ?DB2 Diagnosis Guide and Reference? I would like you all to answer for me today. Based on the responses I receive, I will decide whether I should continue publishing a blog post about it.
    A poll about the use of a DB2 CHAR data type(Posted Tuesday, July 28, 2015) You all have always been very helpful to me in the past when I have been trying to track down information. Well, today I am asking for that assistance once again. I have a polling question about how a certain column type in a DB2 table is being used. I am very interested in value you are using in relation to the DB2 Accelerator. The value you are specifying is of great interest. This question?s intended audience is primarily users of the DB2 Accelerator.
    Updated DB2 11 & DB2 10 Diagnostics Guide and Reference are now (Posted Saturday, July 18, 2015) If you have a product license for DB2 11 for z/OS or DB2 10 for z/OS, it?s time to get your updated copy of the Diagnosis Guide and Reference. They have just been updated (July 2015).
    Happy Anniversary to my DB2 for z/OS blog(Posted Saturday, July 18, 2015) Happy Anniversary to my DB2 for z/OS blog. You turn 10 years old today. Like being a Father and Grandfather did to me, now my blog is starting to make me feel old. Of course, the cool part about the blog turning 10 years old, it reminds me that this blog existed long before blogging was cool. Now, anyone with any kind of access to a computer has (or could have) a blog, 1 years ago, blogs were few and far between and there were NONE that focused only on DB2 for z/OS.
    "Moving data off z Systems costs millions" - a Guest Blog Post(Posted Saturday, July 15, 2015) You?re in for a bit of a treat today along with something a little different. For today?s post, we are going to have a true expert joining us as our ?Guest Blogger?. During a recent presentation, I was made aware of a very well written paper discussing the cost of moving data OFF of a z System to another platform to run an analytic workload. This paper describes the study, how it was performed, and their observations. If you doing analytics on any platform and some of your data used by your analytics resides on the Mainframe, you should find this information very enlightening.
    Red Alert: For DB2 V10 and DB2 V11 users (2015.07.06)(Posted Monday, July 6, 2015) It appears that in rare situations the DB2 log records could be written with invalid control information, not a good thing. A ?Red Alert? was put out today by the Red Alert subscription service for zSeries to warn customers of this serious situation. This is a situation that should be taken lightly. It issue should be addressed or at the very least reviewed for the potential impact to your installation.
    DB2 11 for z/OS now has accelerator-only table functionality () Have you ever noticed that sometimes you make a statement, and no sooner is it made something comes along and negates it? Then you have to write a new blog post explaining why the first thing you said is no longer true. That is exactly what happened to me the last week. Despite my best efforts, sometimes things just change faster than I can finish explaining my original thoughts.
    IBM webcast on Digital Business(Posted Saturday, July 4, 2015) The digital age has arrived? Again?. It is far more than anything we?ve ever seen before and makes all other ?digital arrivals? seem pale in comparison. With this arrival corporations could excel or fall into to oblivion depending on how this use and manage the massive amounts of untapped data available to them. For me, one of the coolest things, if not THE coolest thing, about this ?arrival? is how a corporation?s success can be profoundly enhanced by IBM z Systems?. the Mainframe.
    I feel I have to point this out about Partition-by-Growth (PBG) table spaces(Posted Thursday June 30, 2015) Here?s the situation. You?re running a DB2 COPY utility creating either full or incremental image copy against a partition-by-growth table space. You have specified the keywords SHRLEVEL CHANGE DSNUM ALL.
    These are just so cool: Accelerator-only tables (Recap)(Posted Thursday June 29, 2015) Over the weekend I published a 4 part series that discussed accelerator-only tables, a new function available to the DB2 Analytics Accelerator that was delivered in the recent release of PTF5. This post is just a recap of the 4 post as links.
