IBM Data Studio if you don't know is a free tool for administering and developing server side / app routines for DB2 (both LUW and z/OS). [Of course there is a lot more to it but I assume you get the concept.] Over time it will replace the DB2 Control Center. So if you're new to DB2 or have been using the Control Center, it is a good idea to get yourself familiar with Data Studio. And an easy way to do that is to attend this webinar on Tuesday Jul 27, at 11:30-1 PM Eastern. You can sign-up here
and as a bonus for attending you'll receive hard copy version of the book: Getting started with IBM Data Studio for DB2.
BTW, you can also download a pdf version
of this book.
