Glexec / Deployment at IN2P3-CC (1)Glexec / Deployment at IN2P3-CC (1)
First setup at CCIN2P3 (may/july 2009)– Setuid/SCAS mode– Glite-WN shared on AFS– But additional module « glite-GLEXEC_wn » not entirely shareable
• /etc/ld.so.conf– no static version of Glexec– LD_LIBRARY_PATH not an alternative because of setuid
• /etc/syslog.conf– Grid environment variables problem
• glexec cleared most of the environment variables• But a glexec wrapper should be now available to rebuild the grid environment
– 2 load-balanced SCAS nodes• Not really tested with a real production load
Tighten collaboration – With Glexec developers– With VO testers (lhcb/atlas)

ARGUS Service asap• Requires to be tested and well-understood
