Autonomous Performance Tuning
I was recently asked by a former colleague of mine to help conduct an appraisal of a large scale Cognos TM1 development project that is planning on sourcing all kinds of data from a large Oracle RDMS. In addition to the “normal” review objectives (is the design appropriate? are best practices being followed? will the […]
Performance Testing Your Cognos TM1 Application
Performance testing a TM1 model begins with understanding performance testing in general. Performance testing is an iterative process and the expected outcome (acceptable performance) will be based upon both the TM1 application and the environment it is deployed in. The goal of performance testing is to identify response times, throughputs, and resource utilization of the […]
Leveraging Existing Cognos TM1 Components
Abstract Eventually, you will (hopefully) have developed and delivered something in TM1 that is unique enough (and adds significant value) that you’ll want to leverage it in other models. Leverage Considerations Before leveraging your component, the following must be considered: General Business Requirements (do your business requirements match the delivered components business specifications?) Component Mechanics […]
Cognos TM1 Rules – how do they really work?
Since Cognos TM1 uses a very efficient data compression algorithm to allow large datasets to fit in relatively small amounts of RAM, TM1 calculates the values only when needed by TM1—resulting in improved performance and reduced storage requirements. Here is the sequence of events: A value is requested from (a […]
