Specifying processor affinity

Use the aff option of the VPCLASS parameter to specify the processors to which you want to bind CPU VPs or AIO VPs. When you assign a CPU VP to a specific CPU, the VP runs only on that CPU. However, other processes can also run on that CPU.

The database server supports automatic binding of CPU VPs to processors on multiprocessor host computers that support processor affinity. Your database server distribution includes a machine notes file that contains information about whether your version of the database server supports this feature.

You can use processor affinity for the purposes that the following sections describe.
