Add and drop virtual processors in online mode

You can add virtual processors to meet increasing demands for service while the database server is running.

If the virtual processors of a class become compute bound or I/O bound (meaning that CPU work or I/O requests are accumulating faster than the current number of virtual processors can process them), you can start additional virtual processors for that class to distribute the processing load further.

For more information, see Add virtual processors in online mode.

Windows only: In Windows, you cannot drop a virtual processor of any class.

While the database server is running, you can drop virtual processors of the CPU or a user-defined class. For more information, see Set virtual-processor configuration parameters.
