Db2 Experts on a Data Science Quest
AWS S3 is a cloud object storage service that is easy to use. It is highly available and offers ELEVEN nine’s of durability.
I have quite a few blog entries over the years on backup and recovery.… Read the rest

Note: the statements in this entry are my opinions. I quote IBM once in this article, and that statement should be seen as the only pure fact here. I invite IBM and others to add their perspective in the comments below.… Read the rest
Continue reading »In my last post, I wrote an overview of running Db2 in containers. Today, I’d like to talk a bit about where we get Db2 containers and several common ways they are used. Catch my next post about a critical mistake I think IBM is making with containerization.… Read the rest

One of my steepest learning curves in the last year and a half has been really getting into containers on K8’s and Docker and what running databases within them means. I thought I’d share a general overview, and plan to follow this post with more specific and more technical posts.… Read the rest

There’s a reason why database administration or engineering remains a separate specialty. There are a large number of rabbit holes you can go down. I’m well aware that there’s probably 40% of Db2 LUW alone that I don’t know, even though I’ve spent 20 years working with it, and am an internationally recognized expert.… Read the rest

When writing SQL there are two places you can define how tables are joined. The first is explicit, and is specified after the the keyword ON in the join clause like this:
SELECT *
FROM table_a as a
JOIN table_b as b ON a.id=b.id
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
