-iqnumbercpus iqsrv16 Server Option

Specifies the number of CPUs available to SAP Sybase IQ, overriding the physical number of CPUs, for resource planning purposes.

Syntax

-iqnumbercpus num

Remarks

The value of -iqnumbercpus defaults to the total number of CPUs, but the range of available values is 1 – 128.

Sybase recommends that you use -iqnumbercpus only on:

  • Machines with Intel CPUs and hyperthreading enabled, setting -iqnumbercpus to the number of CPU cores available

  • Machines where an operating system utility has been used to restrict SAP Sybase IQ to a subset of the CPUs within the machine

Setting -iqnumbercpus higher than the number of available CPUs may affect performance.
