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?

Using TM1 Aliases in Cognos BI

Often we build a TM1 dimension using codes or ID’s from another system.  For example Product ID’s or Customer Codes.  These are not particularly usable to most people, so we then usually create Aliases in TM1 as well.  Those aliases are visible through in Cognos BI.  Therefore when defining a dimension in TM1 when it is likely that it will be used in Cognos BI, also add an alias with … Continue Reading

Setting Up Level Names in TM1 for use in Cognos BI
