CPU Pegging

Doesn't IDLE require that a SYSGEN parameter be set? I don't know which one.

OpenVMS V8.3 (V8.2-1 for IA64) or higher use:

Controlled by SYSGEN parameter CPU_POWER_MGMT
and CPU_POWER_THRSH

Is it necessary to run sys$idle_load.exe everytime the system boots for the CPU to IDLE properly?
The reason I ask is that the last thing that the install does is to link sys$idle_load.exe into pcsi$scratch and then run it. If I run it after boot when the CPU is at max, it brings the CPU back down to normal levels.

Galen,

there seem to be 2 different methods for loading and activating SYS$IDLE and there are various 'tricks', which need to be used on the different versions of OpenVMS Alpha. Once installed, SYS$IDLE should load and get initialized automatically during boot.

As you've extracted and analyzed the files from the PCSI kit and have found a workaround for yourself, go ahead and use it.

There should still be a real solution. The author of the IDLE kit will try to diagnose and solve the problem. Just be patient

Ok, let me jump in (as I wrote idle).

You probably have a file named vms$system_images.data in sys$specific:[sys$ldr] which does not belong there.

If that's not the case not then please do this and post the output:

$ dump/block=count=2 sys$common:[sys$ldr]vms$system_images.data

If you run sys$idle_load (which is there in the kit just to load the execelet and avoid a rboot after installation) and it works fine after that then it means that it's just not loaded at boot time, and the file above is critical for that.

Hi Jur. Thank you for your help.

Ok so there's the problem, there's no info for the vms loader at boot time to load the execlet.

Do this:

$ mc sysman sys_loadable add idle sys$idle
$ @sys$update:vms$system_images

This sequence is normally done by the installation procedure.

That should fix the issue unless you get errors doing the above. If you get errors then post what you got.
