Easily Repeating Work

Easily Repeating Work

I love this idea from Ken Fisher: saving your work. I don’t act as a DBA anymore, but when I did, I did something similar. We often logged the scripts we used in a file,  as a part of a log, so that if we broke something and another DBA got a new ticket, they could check what you had done. Over the years, we tried two different methods. First was using the desktop of the instance itself, since we often went to a room to log into the server in those days

The second way was in an Exchange public folder, where we added a new entry for each day. This way we could note the server and the scripts run. Since most tickets were dated, we could easily find the scripts if we were looking at a ticket. Since a user often updated or re-opened the ticket, we could use the public folder as a central note location from the DBA team. We could even point to this folder for our ISO and SOX auditors to show them what had been logged by people who supported the systems. Not a perfect auditing system, but one that often was accepted by auditors.

However, the one thing missing in there, from my perspective, is version control. While I think it is important to track these scripts in a team of DBAs, I also think we want to ensure that as we grow and change these scripts, we know how and why. Junior people can learn from changes made by senior ones, and if a DBA alters one of these scripts and breaks something, just as a developer might refactor code and introduce a bug or break functionality. After all, these scripts are code.

If there is a problem, we want to be able to roll back, which means that we ought to save these scripts into a repository of some sort. While I like the idea of a share that all DBAs can access, I more like the idea of a (secure) Git repository that can be downloaded anywhere, provides a second backup, and can be audited over time. All of these are important features that any enterprise should implement, especially one that is regulated. We want to protect ourselves if a DBA gets hit by the proverbial bus.

I like collaboration, sharing knowledge, and tracking the work you do in a team. It’s important for raising the skills of everyone on the team and helping new members get up to speed quickly. This facilities consistent results, and if done using a tool like version control, helps ensure that your scripts are backed up in a way that preserves the knowledge in your code through any changes made by the team.
