TM1 Forum

I'm faced with the next situation

TM1 server which installed on server with several processor cores. TM1 Application (Contributor application). In application users launch TI processes by click on buttons. And as I see when first user launch TI process it is executed on 1 processor core. When second user launch TI process, it is waiting the end of first process and only after it starts and executing on the same processor core. And other cores are free in this times.

Is it possible to tune TM1 that it starts using other cores in this situation?

in .cfg file put ParallelInteraction=T
by default - so apparently the thing is in something else.

Think you need to read the whole of the IBM best practice note, especially as regards locking, and look at what's going on in your server log.

There is a good section on this in the new IBM tm1 book,
But check out this it might help (thanks to Ben Hill http://blog.tm1tutorials.com/?p=431)
Also what version of Tm1 9.5 are you on?
