How to bind interrupts on a specific CPU

Hello,

we practise our server with operating system ReliantUNIX 5.45 and we are using Informix Dynamic Server 7.31.

I ascertained a lot of cpu interrupts per second (int/s). The count of int/s exceeds critical maximum value considerably.

Machine specific notes for Informix Dynamic Server 7.31.UD5 product release (date 09 Sep 2002) depicts increasing performance by doing a binding interrupts.

Is it possible to bind all interrupts on a specific CPU by using operating system reliant unix 5.45 ?

How can I bind all interrupts on a specific CPU ?

Thank you for your help !

Best regards

The only OS where I can recall seeing that ability is on Solaris. The program is psradm. I don't know how to do it on any other OS though.
