Specify the Number of Virtual Processors

Use VPCLASS cpu,num and VPCLASS aio to specify the initial number of VPs for the CPU and AIO classes. For more information, see VPCLASS.

The VPCLASS configuration parameter allows you to specify, for each class of virtual processors, the number of VPs that the database server should start on initialization. Alternatively, you can use NUMCPUVPS and NUMAIOVPS to specify the initial number of VPs for the CPU and AIO classes. However, you cannot use both VPCLASS and NUMCPUVPS and NUMAIOVPS in the same configuration file. If your ONCONFIG file contains conflicting parameters, oninit returns one of the following messages:

oninit: Can't mix VPCLASS cpu and NUMCPUVPS, SINGLE_CPU_VP, AFF_SPROC, AFF_NPROCS, or NOAGE 
        parameters

oninit: Can't mix VPCLASS aio and NUMAIOVPS parameters

For more information, refer to VPCLASS.
