Grid certificate management
To use the GENIE database system and any Grid resource managed by the Globus Toolkit you will need an X.509 cetrtificate. The UK e-Science community has its own Certification Authority and UK based members of the GENIE project can obtain a personal certificate from this authority. Details of how to obtain a UK e-Science personal certificate are avilable here along with instructions of how to prepare a certificate for use with the GENIE Toolbox.

In order to access the GENIE database or utilise Globus managed compute resource a proxy certificate must be instantiated. This is a time-limited self-signed certificate that authenticates you on the Grid. A proxy certificate can be instantiated in GENIELab by calling the gd_createproxy function.

The default proxy certificate will be valid for 12 hours after creation. It is important to note that any job that is submitted to a Globus managed resource is only valid for the lifetime of the proxy. If you were to submit a job that required 18 hours of compute time, the job would fail after 12 hours. The GENIE Toolbox insists that you specify a maximum execution time for a model run and will check that your proxy certificate will outlive the job. The default of 12 hours is a little restrictive - to change the lifetime of your proxy certificate click the Options button.

A user should only need to adjust the liftime entry for their certificate to ensure that the proxy will outlive the jobs that they wish to submit. Once a suitable lifetime has been selected click Apply to return to the creation dialog. The certificate password should be entered and the Create clicked.

Once the proxy certificate has been successfully created a dialog will inform the user.

Click OK to return to the original dialog. Click Cancel to close the dialog. Unfortunately, the third party library places Matlab in the paused state so a further key press is required to return to the Matlab prompt.
