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 which creates up an environment variable containing the queue name. 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 + "\" )")

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()
The ENV/GLITE runtime environment should then contain the following in addition to any existing contents:
if [ "x$1" = "x0" ]; then # Set environment variable containing queue name env_idx=0 env_var="joboption_env_$env_idx" while [ -n "${!env_var}" ]; do env_idx=$((env_idx+1)) env_var="joboption_env_$env_idx" done eval joboption_env_$env_idx="NORDUGRID_ARC_QUEUE=$joboption_queue" fi
