Issue/Introduction

Looking for assistance on how to disable CPU throttling on a linux server to be able to upgrade CAPC

Environment

Dx NetOps Performance Management any version

Resolution

The following is the documentation from vertica

https://www.vertica.com/docs/10.1.x/HTML/Content/Authoring/InstallationGuide/BeforeYouInstall/cpuscaling.htm

Its disabled in the BIOS.  We don't have any specific documentation on how to do that

Here is a  VMWare knowledge doc: https://kb.vmware.com/s/article/1018206.

It talks about how to do this for manufacturers like Dell and HP but the process would likely vary a bit depending on the manufacturer / model for the systems the DR's are installed on

Additional Information

If you cannot disable CPU scaling through the system BIOS, you can limit the impact of CPU scaling by disabling the scaling through the Linux kernel or setting the CPU frequency governor to always run the CPU at full speed.

Some linux systems however, don't have a governor to configure the CPU frequency.  Please consult your system administrator
