Delegating Proxies to ARC CEs

In the case where automatic proxy delegation from a myproxy server to an ARC CE (via WMS) is not possible, users can delegate credentials direct from their UI using the following script:

#!/bin/bash

# simple bash script to renew job proxies on ARC CEs
# put it in your crontab

CEs=(arc-ce01.gridpp.rl.ac.uk
     arc-ce02.gridpp.rl.ac.uk
     arc-ce03.gridpp.rl.ac.uk
     arc-ce04.gridpp.rl.ac.uk
     t2arc01.physics.ox.ac.uk)


for CE in ${CEs[@]}; do
    arcsync -c ${CE} -f

    # only renew running or queued jobs
    for status in Q R; do 
	arcrenew -c ${CE} -s INLRMS:${status}
    done

    # clean failed or deleted jobs
    for status in DELETED FAILED; do 
	arcclean -c ${CE} -s INLRMS:${status}
    done
done

Naturally one can envisage different ways of populating the list of CEs, this is left as an exercise for the user.
