Lots of DLL's under service/user account Temp folder which is used to configure DEM

One of the users of vRA asked a question on why do we see so many DLL's under Temp folder of a user account configured to run DEM's


Tried to check the same in my environment and found that it's same behavior on my side as well


As shown in the screenshot below DEM Worker and Orchestrator are configured

with a service account named "prem\srv-vra-seven"


Selected one of the DLL's and opened it with notepad ++, not a right tool to open but it did give enough information on what's creating these files under *Temp/*

If we observe the dll , it states that it might be created due to UpdateCatalogWorkflow


UpdateCatalogResource workflow is triggered by DEM

If we observe timestamps in the above screenshot, it's the same time when the folders with the DLL's in them are created




Details of what this UpdateCatalogResource does is present under DEM logs

These folders can be deleted and should not impact any of the underlying components.


!!! Hope this helps !!!
