The term “DevOps” is occupying a lot of space in articles, presentations, and blogs lately. But it doesn’t apply to the mainframe or Db2 on z/OS… or does it? As Db2 DBAs, we’re too busy keeping the lights on to worry about a trend that affects only distributed and mobile apps. But the truth is that many of those apps access Db2 data on z/OS, and … [Read more...]

Cloud use is widespread in most IT organizations today. AWS, Google, Microsoft and other companies offer options for hosting and running x86 environments but these providers don’t have options for clients running workloads on IBM’s z/OS® operating system or mainframe platform. If your organization is exploring ways to achieve cloud benefits in your … [Read more...]
IDUG North America this year is being held in downtown Philadelphia – at the Loews Philadelphia Hotel. IDUG is the premier Db2 event worldwide, and it reaches its 30th birthday this year. Yes – you read that right! The first IDUG NA (and the first IDUG conference anywhere) was held in Chicago in 1989. In those days, IDUG was the ONLY place to go to … [Read more...]

Common to these systems: if the data is not available, critical processing stops. Something you … [Read more...]
Avoid the big tax payment due. It’s tax season, and we’re all trying to optimize to ensure we don’t get hit with a big bill at the end of another year. If you’re like me, I try to aim for the big zero—meaning I don’t owe a large sum in April, but I also don’t receive a huge refund (which means I’m an interest-free lender to the government). … [Read more...]

I’m writing about partial rebalances in Db2 today because they are an effective tool to optimize your applications. Partitioned tablespaces are important because they allow parallel processing of different parts of the data, facilitating many users retrieving data at once. I like to think of it like a bank with many ATMs. Instead of standing in a … [Read more...]
With all the focus on data privacy and the increased cost and efforts organizations are putting into it, do we really need ANOTHER piece of legislation to have to comply with? I’ve spent the last twelve months following the GDPR story. At first it was part of a simple presentation I was to give to some our executive customers, an example of … [Read more...]
