If the security control cube is sparsely populated, this results in unnecessary processing and a longer loading time. An example of a sparsely populated security cube would be one that has a greater ratio of default security settings compared to defined security settings.
Parameter type: optional, static
To address this issue, the PrivilegeGenerationOptimization parameter can be added to the Tm1s.cfg file as follows:
PrivilegeGenerationOptimization=T
When this parameter is set to T, the Cognos® TM1 server will read only the populated cells in security cubes. In the case of a sparsely populated security cube, this will dramatically shorten the Cognos TM1 server's load time.
