Cubes (including Cognos PowerCubes and Dynamic Cubes, as well as other file-based cube technologies) are well-known, commonly used, and valuable data sources in reporting.  As specially indexed binary files, report performance with cubes is generally robust, however when cube files grow very large (or there is high simultaneous demand reading from the cube), response time can and will decrease. That’s why it can sometimes be useful to show cube sizes on BI reports to let authors know when a cube’s size could be affecting performance. Read more

There is a plethora of content available on utilizing the various TM1 functions, but what happens when these functions do not work as expected? What do you do when a rule does not return the expected value, a TI process does not load the values you had hoped for, or a cube’s performance is below acceptable levels? This article will cover some techniques for debugging TM1 that you can use to resolve issues with rules, TI processes, and cube performance. Read more
