    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.

It can be set to AUTO or to an integer value between 0 to 99 and is used as the default for the PCTFREE FOR UPDATE small_int keyword on a CREATE or ALTER TABLESPACE SQL statement when a value is NOT specified.
