Once you have your certificate and you are registered to a VO, you are ready to submit jobs to the grid. To do this you must have an account on a UserInterface machine and you must copy there your personal certificate.

If you haven't already copied your certificate in the UserInterface, please get back to the document INFN-GRID personal certificates howto on the page Get your certificate.

voms-proxy commands

voms-proxy-init -voms YOUR_VO (e.g. voms-proxy-init -voms bio)

instead of the traditional grid-proxy-init. Your certificate subject will not be listed anymore on CEs and SEs gridmapfiles (but it will be still needed on the ResourceBroker).

If you are a software manager use the syntax

voms-proxy-init -voms YOUR_VO:/YOUR_VO/Role=SoftwareManager

(e.g.: voms-proxy-init -voms bio:/bio/Role=SoftwareManager). Use the command:

voms-proxy-info -all

to see the VO credentials stored in your proxy.

myproxy commands

You may let the WMS contacts the myproxy server specified in your jdl in order to renew your credentials:

• myproxy-init -d -n -R 'FQDN.OF.YOUR.WMS.SERVER'
• voms-proxy-init -voms …
• glite-wms-job-submit … … …

or if you need an always fresh voms-proxy for an automated tool, you may follow this simple receipt:

• credentials generation (-R Allow specified entity (wms) to retrieve credential):

$ myproxy-init -d -R 'wms001.cnaf.infn.it'
