One of the many ways to improve database performance is to tune SQL queries running in your environment. Two primary reasons for tuning are: Minimize Response Time – End users who are interacting with data want that data as quickly as possible. It may be mission-critical data ( e.g. medical, financial).

Wearing too many hats? A look at the many roles of today’s DBAs
Once upon a time, database administrators (DBAs) were responsible for as few as one or two database platforms. They had time for things like lunch. Real lunches. Not stress snacks, devoured over keyboards, leaving crumbs wedged between the keys. Back in the day, DBAs had time for friends, for family. They even had energy left over for hobbies. But new tech advancements meant new responsibilities. And that overwhelming...

Monitoring Workload – Heads or Tails, it's two sides of the same coin
I often get asked about monitoring SQL workload that is consuming a database instance’s resources. The first question that comes to my mind is, “What is the symptom you are trying to resolve?” Are you looking to understand the root cause of compute resource consumption such as CPU, I/O, memory and timing? Or are you looking to get to the bottom of a specific set of wait events that have been present...
