  • OLAP Aggregation Specification In DB2 For i 7.3

    May 10, 2016 Michael Sansoterra

    I’m always surprised at how well-attended my RDi debugging presentations are. After all, once you know about service entry points, there’s not a huge amount that’s new and radically different about debugging, even with RDi. Then again, I’m constantly learning new things. Here’s something I learned just last week, in fact.

    Let’s assume that you already have a debug session running on the troublesome program and we’ll look at setting and using breakpoints. The most obvious and common way to set one is to position your cursor on the statement where you want it. From there, you can use
