Db2 Experts on a Data Science Quest
I would like to begin by thanking Ember for allowing me to be a guest blogger and explaining the motivation behind writing this blog.
The “need for speed” in today’s world has led to a sweeping reform where old ideas are discarded too rapidly.… Read the rest

I thought I’d share an overview of the real-time monitoring options for Db2 (LUW). This article focuses on comparing the options, with links to deeper information on each tool.
First a quick overview of the types of monitoring that every DBA should be doing.… Read the rest

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

The IT industry is a change machine. It is full of change. It always has been. As I get older, I wonder if it really is changing more, or if I’m just becoming set in my ways.
The first time I heard the term “DevOps” many years ago, I thought of it as a ploy for developers to get access directly to production.… Read the rest

I have recently encountered an interesting issue – after an IPS (Intrusion Prevention System) upgrade, client applications suddenly stopped being able to connect to some database instances – not all of them, but just a to a subset.… Read the rest

I have been recently tasked with creation of an early warning solution for a memory condition from which some of our DB2 databases have been occasionally suffering. Once the condition is encountered, the only resolution is to restart the instance which can cause an impact.… Read the rest

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

The IDUG Virtual conference kicked off today, and I thought I’d share my excitement and a few observations.
Today was mostly the opening keynote and the spotlight sessions. Recordings of Monday’s sessions will be available on-demand for conference attendees later in the week, so if you haven’t even registered yet, do so and replay them.… Read the rest

If you’ve read the blog for a while, you realize I’m a big fan of the IDUG conferences. I’ve gone to the North American one every year for the better part of a decade now, and the European one for several years.… Read the rest

Db2 is a bit unusual among RDBMSes in that it does not perform authentication. No matter what, you need some external authority to perform authentication. Usually that is either the OS or LDAP, though there are other options. If using LDAP, either transparent LDAP or security plugins can be used.… Read the rest

It has been a while since I wrote one of these, and it’s about time!
In June of 2018, I set a new goal for myself.

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

On May 19 and 20, IBM is hosting several tracks of great sessions. Some of these come out of content that would have happened at THINK, and others are collaborations with the user groups from various technologies.… Read the rest
