Setup to allow gLite-WMS jobs to run

Create an empty file /usr/etc/globus-user-env.sh on all worker nodes.

Setup for LHCb

A default runtime environment must be setup. This can be done by adding the following line to the [grid-manager] section of /etc/arc.conf:

authplugin="PREPARING timeout=60,onfailure=pass,onsuccess=pass /usr/local/bin/default_rte_plugin.py %S %C %I ENV/GLITE"

This sets ENV/GLITE as a default runtime environment. The file /usr/local/bin/default_rte_plugin.py is:

#!/usr/bin/python
"""Usage: default_rte_plugin.py <status> <control dir> <jobid> <runtime environment>
Authplugin for PREPARING STATE
Example:
authplugin="PREPARING timeout=60,onfailure=pass,onsuccess=pass /usr/local/bin/default_rte_plugin.py %S %C %I <rte>"
"""
def ExitError(msg,code): """Print error message and exit""" from sys import exit print(msg) exit(code)
def SetDefaultRTE(control_dir, jobid, default_rte):
from os.path import isfile
desc_file = '%s/job.%s.description' %(control_dir,jobid)
if not isfile(desc_file): ExitError("No such description file: %s"%desc_file,1)
f = open(desc_file) desc = f.read() f.close()
if default_rte not in desc: with open(desc_file, "a") as myfile: myfile.write("( runtimeenvironment = \"" + default_rte + "\" )")
return 0
def main(): """Main"""
import sys
# Parse arguments
if len(sys.argv) == 5: (exe, status, control_dir, jobid, default_rte) = sys.argv else: ExitError("Wrong number of arguments\n"+__doc__,1)
if status == "PREPARING": SetDefaultRTE(control_dir, jobid, default_rte) sys.exit(0)
sys.exit(1)
if __name__ == "__main__": main()
