How to submit simple jobs onto the Grid

Line: 8 to 8
  After you have logged onto a UI machine, you are able to submit commands to the Grid.
Changed:
<
<
You should have your Grid user key files usercert.pem and userkey.pem under ~/.globus directory. If they are located, for whatever reason, under an alternative location, it can be told to the Grid applications by setting the following environmental variables, like:
>

You should have your Grid user key files usercert.pem and userkey.pem under ~/.globus directory. If you have a certificate in PKCS#12 (.p12) format, you can convert it to PEM encoded certificate and private key using the following to commands:
openssl pkcs12 -in cert.p12 -clcerts -nokeys -out usercert.pem
openssl pkcs12 -in cert.p12 -nocerts -out userkey.pem

If they are located, for whatever reason, under an alternative location, it can be told to the Grid applications by setting the following environmental variables, like:

  export X509_USER_CER=/some_directory/globus/usercert.pem
Line: 42 to 46
  If you are member of more then one VO, you can choose between them by using the glite-voms-proxy-init for logging in, instead of grid-proxy-init command. E.g.:
Changed:
<
<
> glite-voms-proxy-init -voms hungrid Or:
>
>
> voms-proxy-init -voms hungrid Or:

> voms-proxy-init -voms hungrid -valid 04:00

 
Changed:
<
<
> glite-voms-proxy-init -voms hungrid -valid 04:00
>
>
By default, voms-proxy-init generates a proxy valid for 12 hours. You can request a maximum validity of 24 hours. Be aware that if your proxy expires when your jobs are still running (or waiting), they will abort automatically. You should use MyProxy (see below) for long-term jobs, or when submitting a lot of jobs (more than 200).
 
Changed:
<
<
To get information on your user proxy, you can use the commands grid-proxy-info or glite-voms-proxy-info -all. You can destroy your user proxy by grid-proxy-destroy or glite-voms-proxy-destroy.
>
>
To get information on your user proxy, you can use the command voms-proxy-info -all. You can destroy your user proxy by voms-proxy-destroy.

Line: 141 to 147
  For further information, look at the man pages of the above commands, and maybe also to the man pages of other glite-wms- commands. For further references on simple job submission, see https://edms.cern.ch/file/722398//gLite-3-UserGuide.pdf. Also a complete description of the JDL language is available there.
