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)

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()
