Wow – one of our reference projects went into the Yahoo Finance webpages. Carol Tagliaferri (my direct manager) worked with CSX, one of the largest US based railway companies, over a longer period together with the RAT team, and helped CSX to successfully upgrade and migrate their database landscape to Oracle Database 11.2.
Plus: We did present about CSX at Oracle Open World 2012 as this project is a perfect showcase for:
(a) an Upgrade project with many databases
(b) over a longer period of time
(c) using Real Application Testing decreasing the testing effort by factors!
And that is what Maritza Gonzalez, Technical Director at CSX said:
comprehensive and flexible solution for assessing the impact of the Oracle 11g
database upgrade into CSX systems. At CSX we were able to capture real
production workloads, replay it in the
11g environment, identify poor
performing queries and, fine tune these queries in a test
environment before the production
More details on the actual project are included in our OOW 2012 talk (slides 35-42).
