The database server supports automatic binding of CPU virtual
processors to processors on multiprocessor computers that support processor
affinity.
Your database server distribution includes a machine notes
file that contains information about whether your database server
version supports this feature. When you assign a CPU virtual processor
to a specific CPU, the virtual processor runs only on that CPU, but
other processes also can run on that CPU.
Use the VPCLASS configuration
parameter with the aff option to implement processor affinity
on multiprocessor computers that support it.
The following figure
illustrates the concept of processor affinity.Figure 1: Processor affinity
UNIX only: To see if processor
affinity is supported on your UNIX™ platform,
see the machine notes file.
