TD Ameritrade needed to identify, outline and implement performance tuning measures against existing IBM Netezza Servers (Twinfin 24).


iOLAP implemented best-practice architecture to achieve efficient query retrieval on existing, high-usage installations, including Skimmer IBM Netezza Servers (Development), Twinfin24 IBM Netezza Server, and a new Striper (N2001). The iOLAP team defined and implemented a new ‘Statistics and Groom Strategy’, to increase performance lift and lessen the impact on users. This included a proof of concept to change data types from numeric to appropriate integer size. The team also reviewed current security implementation and worked with DBA to implement improvements to take advantage of GRA.


TD Ameritrade now has DBAs trained in Netezza best practices, and installations fully optimized to deliver operational efficiency to various business units.
