Set virtual-processor configuration parameters
Use the VPCLASS configuration parameter to designate a class of virtual processors (VPs), create a user-defined virtual processor, and specify options such as the number of VPs that the server starts, the maximum number of VPs allowed for the class, and the assignment of VPs to CPUs if processor affinity is available.
The table lists the configuration parameters that are used to configure virtual processors.
| Parameter | Description |
|---|---|
| MULTIPROCESSOR | Set to 1 to support multiple CPU
virtual processors, or to 0 for only a single CPU
VP |
| NETTYPE | Specifies parameters for network protocol threads and virtual processors |
| SINGLE_CPU_VP | Set to 0 to enable user-defined
CPU VPs, or to any other setting for only a single CPU VP |
| VPCLASS | Each defines a VP class and its properties, such as how many VPs of this class start when the server starts |
| VP_MEMORY_CACHE_KB | Speeds access to memory blocks by creating a private memory cache for each CPU virtual processor |
