First of all, let's start with a simple job. Let's run sleep 1. Here's the JDL.

 

[heri@fep-53-2 ssam]$ cat test.jdl
[
executable="/bin/sleep";
arguments="1";
]

Second thing, let's load the environment (see module implementation also).

 

[heri@fep-53-2 ~]$ . /opt/gLite/gLite-UI-3.2.4-0-Prod/etc/profile.d/grid-env.sh
[heri@fep-53-2 ~]$ voms-proxy-init --voms seegrid
Cannot find file or dir: /export/home/heri/.glite/vomses

Let's find our CREAM-CE directly

[heri@fep-53-2 ssam]$ lcg-infosites --vo seegrid ce | grep gw02
   8       0       1              0        1    gw02.seegrid.grid.pub.ro:8443/cream-pbs-seegrid

 

And run it:

[heri@fep-53-2 ssam]$ glite-ce-job-submit -a -r gw02.seegrid.grid.pub.ro:8443/cream-pbs-seegrid test.jdl
2009-11-06 13:54:38,956 WARN - No configuration file suitable for loading. Using built-in configuration
https://gw02.seegrid.grid.pub.ro:8443/CREAM698419717

 

We can list our jobs:

[heri@fep-53-2 ssam]$ glite-ce-job-list gw02.seegrid.grid.pub.ro:8443
2009-11-06 14:06:40,995 WARN - No configuration file suitable for loading. Using built-in configuration
https://gw02.seegrid.grid.pub.ro:8443/CREAM698419717

 

We can check their status:

[heri@fep-53-2 ssam]$ glite-ce-job-status https://gw02.seegrid.grid.pub.ro:8443/CREAM698419717
2009-11-06 14:05:53,435 WARN - No configuration file suitable for loading. Using built-in configuration

        Status        = [IDLE]
[heri@fep-53-2 ssam]$

 

And we can get the output:
