Good blogs keep popping up and other blogs fade into the back ground, so it’s hard to keep track of the good stuff out there. The following is a list of blogs I have either in the past gotten a lot out of or currently do. It would be great to get comments on what the best current blogs are and then iterate on this list and keep it updated.

Successfully managing a modern organization’s complex data estate requires careful work at multiple layers, from the implementation of organization-wide data policies and platforms to the careful tuning of particular databases.

Greening of Storage

By Tim Gorman

Anyway, that statement resonated with me, because although I change residences every few years, it has only been (more...)

I see Delphix as amazingly positioned at nexus of data (more...)

There is more and more happening in the world of visualization and visualizing Oracle performance specifically with v$active_session_history.

Of these visualizations,  the one pushing the envelope the most is Marcin Przepiorowski. Marcin is responsible for writing S-ASH , ie Simulated ASH versions 2.1,2.2 and 2.3. See
