Heat map for Redo Size in SQL Developer...

Submitted by dave on Tue, 03/08/2016 - 11:23

I've gotten a lot of mileage out of my old SQL Developer Archive Log Count Heat Map report that I created in SQL Developer. I was recently asked to estimate the amount of redo that might be sent to a DataGuard standby. Searching The Google for this and I found some methods for calculating Network Bandwidth but I wanted to start with raw redo generated from an instance using information from v$archived_log.

Due to some unforeseen circumstances I was unable to spend as much time as I would have liked at KScope13 in New Orleans but boy did I pack a lot into the 24 hours that I was there.

Updated Heat Map Report

Submitted by dave on Wed, 10/24/2012 - 23:50

During my preparation for a visualization presentation at East Coast Oracle Users Group I realized I had an opportunity for a teaching moment on Levels of Abstraction. A few months back I published my PL/SQL code for an Archived Log Switch Heat Map.
