CPU informix
Licu Garcia asked how to limit Informix to 2 of 4 cores. Art Kagel pointed to the VPCLASS cpu entry in onconfig. Nestor Gomez Munoz showed VPCLASS cpu,num=3,noage,aff=2-18 on a Sparc to bind CPUs. Khaled Bentebal added NUMCPUVPS for versions before 9, VPCLASS from IDS 9, and that CPU VPs can be added online with onmode. Solved.

how to configure CPU with informix. For example, if i have 1 CPU with 4 cores and i want to assign only 2 cores. What is the correct parameter on onconfig file for this? Thank you for your answers.
See the vpclass entry for class cpu in the onconfig file. Art Sent from my Galaxy S®IIILICU GARCIA <licu99@gmail.com> wrote:how to configure CPU with informix.

Depending on the version of IDS that you are using, you can use
NUMCPUVPS x for the previous versions (prior to version 9)
or
VPCLASS cpu,num=x,noage for the latest versions starting IDS 9 (x is
the number of CPU VPS that you want to configure)
Note: you also have other optional parameters for the VPCLASS parameters
You can also add CPU VPS online if you want using the onmode command.

Thank you very much. Now I understand how to configure the CPU.
