Using xrootd in a batch job

ROOT

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 ./myjob.sh 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.

Thanks

Hi,

You’d have more luck hn-cms-wanaccess@cern.ch – 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.

Cheers,
Matevz
