>>>I did see the discussion

Hi all.

I saw this on appeared in many cases but I did not see any resolution.

I am working with 2013 update 8, collecting on a remote machine and copying the results for the GUI stuff.

I am trying to run lightweight hotspots analysis with stacks and can not.

working without stacks is successful:

This is why I think all my drivers are working fine.

# ./amplxe-cl -collect lightweight-hotspots --duration 10

To avoid this situation, disable all "Cn(ACPI Cn) report to OS" BIOS options before sampling with VTune Amplifier on such systems.

however trying to add stack collection causes this db issue:

first I can see that this makes me add a pid to attach to (why?, can't I do this system wide?)

when adding the pid and the request for stacks I get the failures and the .tb6 file is not generated.

When I try to open this in the GUI it fails.

# ./amplxe-cl -collect lightweight-hotspots --duration 10 -knob enable-stack=true -target-pid 3594

Sorry for late answer.

Regarding the results of the discussion I think that database error issue can be solved by VTune devs and we only can speculate about the possible culprit.
