My Journey through Beginner Data Science Content

When I first started learning about data science, the amount of material out there was daunting. It is hard to find your way in what you should learn and how you should learn. I thought I’d share what has been working for me and what didn’t.… Read the rest

First Look – The New Replacement for db2top and dsmtop – dmctop!

One topic that comes up at most panels, Technical Advisory Board meetings and other longer interactions I participate with for IBM is DBA’s love of db2top. It is such an easy tool, and one that most DBAs I know choose over all others for real-time monitoring and basic investigation of a database.… Read the rest

Disappearing Data in PostgreSQL

I recently discovered an interesting (and frustrating) issue while running PostgreSQL in Kubernetes. While the issue technically isn’t specific to Kubernetes, per se, it is certainly easy to encounter in Kubernetes for users of the official PostgreSQL Docker image (and many other images) mounting volumes somewhere other than the default location.… Read the rest

The DBA is Dead? No, the DBA as Gatekeeper is Dead!

I still remember this meeting when I had been a DBA for less than a year at IBM. It was IBM, so I was the lone primary DBA for this internal client. With 3 whole months of experience and a shiny college degree.… Read the rest

Index of Introductory Db2 Topics

This blog entry is designed to serve as a roadmap for current blog entries directed at those newer to Db2. In my mind, this likely includes anyone who has been working with Db2 for less than 2 years. However, often there are areas we spend more time in than others, so I think of these topics also as "spackle" - to fill in gaps for the self-taught. Note that some of the topics below are not links. This is because they're areas I plan to blog about in the future. Continue reading »

Registry Variables and DB2_WORKLOAD=WC

I was happy to see the new workload registry variable in Commerce 7/DB2 9.
