Using xrootd in a batch job

Dear Experts,
I initially submitted a ticket to CERN service desk but I was redirected here. I am trying to run a batch job at the SLC5 node but always get the following error:

I tried executing batch script by doing ./ and it runs fine. I have been working on this for days without much success. Let me know if the information I gave is insufficient.


I wonder if this is the right place for my question. Please let me know. Thanks.



You’d have more luck – the CMS hypernews forum.

It seems you were not able to login into desy … you’ll need a valid proxy certificate for this. Some latest dcache versions don’t accept xrdgsiproxyinit generated proxies (I know this was an issue at FNAL) … but voms-proxy-init should work in any case.


I have emailed them. Thanks a lot.
