I was trying to run a job through CCS, which drives an application (Solidworks, to be more specific) installed on the compute nodes through its COM based API. When running in the interactive log on mode, the job runs without any problem. However, as a CCS job, it always fails to launch the application process, with a COM exception:
Retrieving the COM class factory for component with CLSID {XXX} failed due to the following error: 80080005
My guess is that the security context of a CCS job is somewhat different from that in an interactive log on. I have given the submission user full rights over the compute node but that didn't help either.
When we start jobs on the compute nodes we log on as the user that submitted the job. We do not log into the interactive session, but I don't think that's the problem here.
Is Solidworks installed locally on the compute node or are you running it from a network share?
Have you tried logging in locally as a user on the compute node to run a solidworks job?

Yes Solidworks is instaled locally on the compute node. I tested the
job on the compute node and it ran without any problem locally. The COM
exception only happened when running through CCS.
I googled the
error and the only (not so perfect) solution I could find so far is to
change the DCOM config of the Solidworks application to 'run as an
interactive user'. When there is an interactive user session on the
compute node, the Solidworks app can start within that context. This
requires a user to log on to the compute node locally though, which is
not desired in a cluster environment.
It seems that by not logging into the interactive session, some
security rights/context are missing for the job. Not too sure what to
do about it.
I've been doing a little research on this end trying to see if there are some simple workarounds for the problem but it keeps coming back to Solidworks and their code. My guess is that they're using some kind of resource in the interactive session, as a result, won't start up correctly in non-interactive sessions.
I can help the Solidworks folks get plugged into our developer support organization if you want to open a support issue with them. I believe they have a full support contract with Microsoft but if they need help navigating all the options I can help. My email is "ryanw" at Microsoft.
Sorry I don't have a clever workaround, ryanRyan Waite - Product Unit Manager - Windows HPC
