I am trying to modify p series linux performance parameters following the below link -
In the end of the link, it mentions that the fields like shared_processor_mode and capped are to be set to 0 and 1 respectively for performance. But, I am not able to modify that file directly opening in vi editor. The change is not saved anyhow.
Is there any alternative way to change this file fields and how can it be done?
After the change is done, does the machine requires reboot?

Re: How to modify /proc/ppc64/lparcfg field values on a power6 RHEL 5.3 machine2009-08-10T12:26:53Z in response to SystemAdminThe values from "lparcfg" simply reflect the definition of your partition.
The partition is defined by the HMC (or in some cases the IVM).
Once you change the values from the HMC, the partition will need to shutdown and re-started.
