    Willie Favero - Getting the most out of DB2 for z/OS

    Welcome to all things DB2 for z/OS. This is your one stop, your only stop, and your final stop to find out all you'll ever want to know about DB2 for z/OS. We'll be discussing how to upgrade to the latest DB2 version, have detailed "how it works" discussions, some performance tips, maintenance alerts, baby updates, with a few guest posts thrown in occasionally. In addition, you'll find all of the latest DB2 news and gossip, arrival notifications of the latest articles, books, seminars, and teleconferences, along with details on all of the major conferences. 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. This is also the place to get that little bit of lite reading each morning to start your day off on the right foot.

    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.
    This is just so cool: Accelerator-only tables (Part 4)(Posted Thursday June 28, 2015) Today?s post is a bit longer than most that I publish and it's in multiple parts; make sure you catch them all. Considering I spend just about all my time performing performance measurements with the Accelerator, with most of those measurements usually around loading data, it?s probably not all that difficult to understand why I get so excited talking (writing) on the subject. This is fascinating technology that is going to benefit lots of people.

    This is just so cool: Accelerator-only tables (Part 2)(Posted Thursday June 27, 2015) Today?s post is a bit longer than most that I publish, more the length of an article. For that reason I have broken it down into 4 parts with each part covering a different aspect of accelerator-only tables; this is Part 2. Since I spend just about all my time performing performance measurements on the Accelerator, with most of those measurements usually around loading data into the Accelerator, it?s probably not all that difficult to understand why I get so excited (and a bit carried away) talking (writing) on the subject. This latest Accelerator enhancement is fascinating technology that is going to benefit lots of people.
    This is just so cool: Accelerator-only tables (Part 1)(Posted Thursday June 27, 2015) Today?s post is a bit longer than most that I publish, more the length of an article. For that reason I have broken it down into 4 parts with each part covering a different aspect of accelerator-only tables; this is Part 1. Since I spend just about all my time performing performance measurements on the Accelerator, with most of those measurements usually around loading data into the Accelerator, it?s probably not all that difficult to understand why I get so excited (and a bit carried away) talking (writing) on the subject.
    June 20, 2015 DB2 for z/OS Product Publication updates for DB2 11 and DB2 10(Posted Friday June 26, 2015) June 20, 2015 sees another major update of a large number of the DB2 for z/OS product publication. Updates for DB2 11 and DB2 10 are now available. Things are now back to usual with all supported version having their publications updated at the same time. This is also pretty close to being an update to all the product publications (for example, 16 of 21 for DB2 11) available to a version. The details, sizes, and download links all follow. Happy reading... and remember there?s nothing better than looking something up in the most current manual, the one that has the latest information available from DB2-land.
