Setting the Java Virtual Machine (JVM) in Cognos

There are a few settings in Cognos BI that can dramatically improve performance in Cognos BI when using TM1 as a data source. The first of these is to stop Cognos from using the old Bluenose method of querying TM1 and force it to use the native TM1 engine. The next setting that we need to configure is the Java Virtual Machine, or JVM. Wikipedia defines a Java Virtual Machine … Continue Reading

Forcing Cognos BI to Use Native TM1 Engine

There are a few settings in Cognos BI that can dramatically improve performance in Cognos BI when using TM1 as a data source. The first of these is to stop Cognos from using the old Bluenose method of querying TM1 and force it to use the native TM1 engine. Bluenose is the default and it is extremely slow on large queries. Anecdotally it appears to want TM1 to return the … Continue Reading

Order to Restart Cognos and TM1 Servers

What order do I use to restart Cognos BI and TM1 servers in a distributed environment? We are currently doing a project where there is a TM1 server, two Cognos BI application servers and a gateway server. The fundamental approach is to stop people from accessing the environment and then stop the applications themselves. The order to stop and start them is the exact reverse of each other. To stop the … Continue Reading

Using “cmplst” files to find the Exact Version and Fix Pack of TM1 Installed?

Sometimes we need to go further than just knowing the version of TM1 installed. We might need to know, for example, the exact version, fix pack and possibly even interim fix that has been installed. To get this information we need to find the “cmplst” file. Where to find the cmplst files for TM1 The cmplst file (for Component List) is usually found in Program Files/IBM/Cognos/TM1_64/. This file lists all … Continue Reading

TM1/Cognos Security Integration Gremlin

Weird. That’s all I can say. We have been doing a significant project with complex calculations done in TM1 and a front end with Cognos BI reports. We now have the integration working perfectly with TM1 cubes performing brilliantly in BI, TM1 cubes able to have data entered into them from Cognos Workspace and security integrated from multiple AD servers via Cognos groups and roles to both Cognos and TM1. Integrated … Continue Reading

TI Connection Error to Cognos BI Report

We sometimes recommend using a Cognos BI Package and BI report as the source for TM1. We usually do this when we have both TM1 and BI deployed at a client and it just makes sense to prepare the data in Framework Manager so it can then be used by any BI report and by TM1 as well. It especially cuts down reconciliation because if it is right in one … Continue Reading
