Revision as of 15:49, 27 January 2009

The EGEE grid infrastructure can be accessed from any Nikhef desktop running Scientific Linux 3 or 4. In order to use the EGEE gLite grid middleware, type

 . /global/ices/lcg/current/etc/profile.d/grid-env.sh        ## bash/ksh/zsh

or

 source /global/ices/lcg/current/etc/profile.d/grid-env.csh  ## csh/tcsh

first. This will set up all required environment variables for running the gLite middleware commands.

(with special thanks to Egge van der Poel for finding all csh related errors ;-))

Type

 voms-proxy-init --voms <YOUR-VO>

to create a voms proxy. Sample output:

 $ voms-proxy-init -voms pvier:
 Enter GRID pass phrase:

 Your proxy is valid until Fri Dec  7 00:08:49 2007

If you see a warning similar to

 Wrong ownership on file: /global/ices/lcg/glite3.0.21/glite/etc/vomses
 Expected: either (0,0) or (UID, GID) = (0, 0)

then you safely ignore it. This is a feature of the voms software.

Congratulations! You are now ready to submit jobs to the EGEE grid using
