Rollback Statements and the IBM Sterling Order Management System

There have been a few times in my career where I have been stunned by something I have seen while at work.

My Early Experience Learning MySQL as a Db2 DBA

I’m a couple of months into working with MySQL, and thought I’d share some resources and thoughts on what I’m learning and what is working.

When an Index is More Than an Index: Clustered Indexes

Many RDBMSes have similar structures and concepts. In this post, I’m going to compare and contrast IBM Db2’s concept of a clustered index and MySQL’s concept of a clustered index.

Index vs. Clustered Index

An index is generally a way of organizing data in a way that it will be quicker to access than scanning through all of a table.… Read the rest

db2u Without RedHat OpenShift – A Container-Native Database!

Earlier in 2021, I wrote an article on the big mistake I thought IBM was making by only offering their container-native version of Db2 (db2u) on RedHat OpenShift.

Well, that article and tirelessly asking questions of EVERY IBMer I could get to listen to me (seriously, I could hear eyes rolling when I asked for the umpteenth time) has finally worked!… Read the rest
