Registering with the BaBar Grid
To use the BaBar Grid, you need
to obtain a Grid certificate from your
national
Certification Authority (CA), register it with
the LHC Computing Grid (LCG -
required since many of the resources we use are shared with LCG),
and register it with the BaBar Virtual Organisation (BaBar VO).
Obtaining a Grid Certificate
The procedure for obtaining a Grid Certificate and registering
it with LCG is outlined on the
LCG Users Registration page.
Since the certificate identifies who you are, obtaining one usually requires
that the CA contact your institution to ensure that you are who
you say you are. This may take a day or two.
Joining the BaBar Virtual Organisation
To be eligable to use BaBar Grid resources you should first have registered for a computer
account at SLAC.
If you don't have a BaBar SLAC account, that should be obtained first.
If, for some reason, that is not appropriate you should contact
the BaBar VO Administrator, Eleonora Luppi,
to be manually added to the BaBar VO. Manual registration
is more complicated, will require special justification,
and in any case may not be fully useful without a SLAC account, so this method
should only be used in special circumstances.
The following describes automatic registration via a SLAC account.
If you have just obtained your SLAC account (or you haven't used it for
BaBar analysis recently), you can check whether it is
fully registered as a BaBar username with access to Objectivity (also required), using
the chkuser command. Unless it shows yes in the
OBJECTIVITY field (ie. that you are in the g-babar:com-obj
SLAC AFS group), your BaBar VO registration will be rejected.
With your Grid certificate loaded into your browser, go to
the babar VOMS server home page and follow the New User Registration link on the left hand side. You will
then be presented with a short form to fill in and sign with your certificate followed by the usual e-mail address
confirmation loop. After you have confirmed you e-mail adress your request to join the BaBar VO will be forwarded to
the BaBar VO administrators and as long as you are eligable they should process your application within a day or two.

the analysis of the data collected by it.
Members and Managers of the VO agree to be bound by the Grid Acceptable
Usage Rules, VO Security Policy and other relevant Grid Policies, and to
use the Grid only in the furtherance of the stated goal of the VO.
