Persistent Feeders can dramatically decrease the time required to restart a TM1 model. Here is an explanation of what Persistent Feeders are and instructions on how to implement them in your TM1 model.
Overfeeding is where TM1 feeders are targetting more cells than are required. This can lead to excess memory consumption and reduce performance. Here we explain over feeding and how to avoid it.
Here we present a fully worked example of how to create element level security for an organisation that requires complete lockdown for entire branches of a dimension. It uses element level security down to the N level, applied via a TI.
Dimension order within cubes in TM1 is important not only for performance, but also for usability. When should you set the order for usability and when for performance? And how do you optimise the dimension order for performance? All these questions and more are addressed in this post from ExploringTM1.
Renaming a TM1 model is relatively easy. To change the name of a TM1 model (or instance or server name) do the following: Open tm1s.cfg for the model concerned. Find “ServerName” Edit the value after the equals sign to reflect the new model name Save tm1s.cfg Open Cognos Configuration for TM1 Change the name of the TM1 Server Save Cognos Configuration Start the TM1 Server (right click, start) in Cognos Configuration … Continue Reading
How to delete a redundant TM1 service from Windows. Sometimes we need to delete a TM1 service. After changing the name for a TM1 model, for example, we may be left with a Windows Service still existing for the old model. This explains how to remove a redundant TM1 server.
This is a fabulous article from our friends at Ironside in the US. The original article is available here. There are various approaches available to enhance the performance of your TM1 application. One such approach is to leverage Stargate Views. Stargate Views are different from traditional view objects and represent cached subsections of cubes that get created through user experience. As users browse cubes via the Cube Viewer or consume cube … Continue Reading
Need to email your TM1 Admin upon a TI failure? TM1 models are usually updated from a third party data source. Sometimes those loads fail and TM1 does a great job in recording in its log files what caused the error. What it doesn’t do out of the box is email the TM1 administrator of the failure. We have a standard method that involves having a process that executes a Windows … Continue Reading
I was just updating the approval hierarchy on a TM1 Contributor model and could not see the changes through on the web app. Odd, I thought. So I did some digging around and found that the solution to that specific problem is to re-save the Rights in Performance Modeller even if you have no rights in there in the first place. Some what counter-intuitive I reckon! So the whole process … Continue Reading
Migrating or Deploying TM1 from one environment to another is difficult. This best-practice guide presents two methods that can be used step-by-step to help ensure that your migration is successful. It also includes a downloadable checklist that you can modify to suit your specific TM1 servers and models.
