On the 20th of April, query load times usually ranged from 12 to 15 seconds per snapshot, but there was a notable spike exceeding 2,000 seconds during certain periods. This anomaly suggested a deeper issue, prompting a detailed investigation. By examining the correlation between locks and application issues, executions, disk reads, and buffer writes, a significant overlap was found between increased query durations and intensified locking issues. Accessing the lock history tab provided detailed data on each lock event, including the time, duration, and specific database elements affected.

Before getting into the technicalities of speeding up your database read queries, the first step is always to have a clear understanding of what exactly you need. This might sound straightforward, but inefficient queries often begin with uncertainty about the data requirements. Knowing exactly what information is necessary for your application or analysis not only helps in crafting precise queries but also prevents the database from retrieving extraneous information, which can significantly slow down performance.

Too often when looking at the data we see just numbers – columns and rows that might seem meaningful on the surface but lack depth without proper context. Data observability changes this perspective. This approach is about understanding what the numbers really tell us about the health, accuracy, and vitality of our data systems.

Data observability isn’t just one thing – it’s an ability, or rather a way of monitoring your data’s health, accuracy, and overall usefulness. It’s what equips data teams with the essential tools they need in order to make sure that the data that’s driving business decisions is not only there but also high-quality, well-structured, and up-to-date.

Trying to gauge the workload of a database on any given day can pose quite a challenge. A straightforward question supported by basic Database Activity Monitoring might not yield an insightful answer if it’s stripped of context, cluttered with arbitrary numbers, and missing crucial details.

So, what’s the right way to address this query?

It may seem that the companies entangled in the web of Oracle and its ecosystem have a limited set of options when it comes to performance tuning. It’s either – pay for extra functionalities and navigate Oracle’s complex licensing, risking non-compliance penalties. This often leads to a conservative approach to optimization, stifling innovation due to the fear of overstepping licensing terms.

But do we always have to go the hard way? 

There’s a much simpler route that doesn’t involve trembling with fear of clicking the wrong thing. That’s what we will be talking about today.
