Parameter type: optional, dynamic
To specify a maximum number of threads to use when processing queries, add the following line to Tm1s.cfg:
MTQ=n
where n represents the number of threads to be used for a single query.
Alternatively, use MTQ=All (case insensitive), which sets the value to the maximum number of cores available on a server. The result is a dynamic system setting that consumes all cores.
If you set MTQ equal to a negative number, that is, MTQ=-N, the number of threads that will be used is defined by the following equation: T=M-N+1, where T= the number of threads to be used by the system and M= the number of threads on the server.
For example, if your server has 64 cores and you set MTQ=-10, the system will use 55 cores.
T=64-(10)+1
If you set MTQ=1 or MTQ=0, multi-threaded query execution is turned off.
For more information, see "Multi-Threaded Queries" in the IBM® Cognos® TM1 Operation Guide.
MTQ is turned off by default.
