- check user certificate
ls -al .globus ls -al .glite
- check available queues and batch system
ldapsearch -x -H ldap://gks-XYZ.fzk.de:2170 -b mds-vo-name=resource,o=grid
- create a user proxy
voms-proxy-init -voms dech
- get the test jdl file : test.jdl
- submit the job
glite-ce-job-submit -d -r <ce_host_FQDN>:8443/cream-pbs-cert -a test.jdl

glite-ce-job-status <cream-id>

Troubleshooting
At the beginning jobs are stuck in REALLY-RUNNING state.
1. Checking in the worker node
ps -ef
a row like
dech021 5591 5586 0 16:12 ? 00:00:00 /bin/sh -l ./CREAM396012076_jobWrapper.sh
will appear in the output. Checking in job output and error in the job directory
cd /home/dech021//home_cream_396012076
ls
CREAM396012076 CREAM396012076_jobWrapper.sh cream_396012076.proxy err_cream_396012076_StandardError out_cream_396012076_StandardOutput
we find an error in CREAM396012076_jobWrapper.sh line 80, and checking, we discover /usr/bin/glite-lb-logevent is missing. To have it installed:
yum install glite-lb-client-progs
2. On the ce start globus-gridftp-server
/etc/init.d/globus-gridftp-server start
