Setting the SINGLE_CPU_VP configuration parameter when using one CPU VP

If you are running only one CPU VP, set the SINGLE_CPU_VP configuration parameter to 1. Otherwise, set this parameter to 0.

Important: If you set the SINGLE_CPU_VP parameter to 1, the value of the num option of the VPCLASS configuration parameter must also be 1.
Note: The database server treats user-defined virtual-processor classes (that is, VPs defined with VPCLASS) as if they were CPU VPs. Thus, if you set SINGLE_CPU_VP to nonzero, you cannot create any user-defined classes.

When you set the SINGLE_CPU_VP parameter to 1, you cannot add CPU VPs while the database server is in online mode.
