Oracle:

Hey DBAs:  You know you can  install and run Oracle Database 12c on different platforms, but if you install it on an Oracle Solaris 11 zone, you can take additional advantages.

A quick update on our native Data Dictionary
Employee +0 Vote Up -0Vote Down

In July 2014, I wrote that we were working on a new native InnoDB data dictionary to replace MySQL's legacy frm files.

This is quite possibly the largest internals change to MySQL in modern history, and will unlock a number of previous limitations, as well as simplify a number of failure states for both replication and crash recovery.

With MySQL 5.7 approaching release candidate (and large changes always coming with risk attached) we decided that the timing to try to merge in a new data dictionary was just too …

Kubernetes is a system for managing containerized applications in a clustered environment. It provides basic mechanisms for deployment, maintenance and scaling of applications on public, private or hybrid setups. It also comes with self-healing features where containers can be auto provisioned, restarted or even replicated. 

Kubernetes is still at an early stage, please expect design and API changes over the coming year. In this blog post, we’ll show you how to install a Kubernetes cluster with three minions on CentOS 7, with an example on how to manage pods and services.

More Cores or Higher Clock Speed?
+0 Vote Up -0Vote Down

This is a little quiz (could be a discussion). I know what we tend to prefer (and why), but we’re interested in hearing additional and other opinions!

Given the way MySQL/MariaDB is architected, what would you prefer to see in a new server, more cores or higher clock speed? (presuming other factors such as CPU caches and memory access speed are identical).

For example, you might have a choice between

  • 2x 2.4GHz 6 core, or
  • 2x 3.0GHz 4 core

which option would you pick for a (dedicated) MySQL/MariaDB server, and why?

And, do you regard the “total speed” (N cores * GHz) as relevant in the decision process? If so, when and to what degree?

DBA Personalities: DISC and Values Models
+0 Vote Up -0Vote Down

What personality characteristics do great DBAs share? What motivates them?

If you’re not sure why you should care, you’re probably not a hiring manager! Hiring and retaining highly skilled people is consistently listed as a top challenge for CIOs. CIOs strongly desire to predict whether someone’s a good fit for a particular role.

Enter the personality profile assessment. These are quantitative tools used by many companies to try to learn as much as possible about candidates during the recruiting process. I thought it would be interesting to know what drives DBAs, so I reached out to a number of great MySQL and PostgreSQL …
