---++ Introduction
Top level BDII server republishes information from site BDIIs.
In order to do this, top level BDII server uses a list of URIs
pointing to site BDIIs. Top level BDII downloads this list
periodically from a
[[http://grid-deployment.web.cern.ch/grid-deployment/gis/lcg2-bdii/dteam/lcg2-all-sites.conf][central location]].

---++ Operation
The list of site BDII URIs is generated by the 
[[https://goc.grid-support.ac.uk/gridsite/bdii/BDII/bin/bdiiconf-gen.pl][bdiiconf-gen.pl]] script
using the information in [[https://goc.grid-support.ac.uk/gridsite/gocdb2/][GOCDB]].

The script itself runs from cron every 30 minutes on [[https://goc.grid-support.ac.uk/gridsite/bdii/BDII/][gridsite]]
producing publicly available [[http://goc.grid-support.ac.uk/gridsite/bdii/BDII/www/bdii.conf][URI list]]. This list
contains all certified, production LCG and OSG sites. Two other lists are created:
   * [[http://goc.grid-support.ac.uk/gridsite/bdii/BDII/www/bdii-osg.conf][bdii-osg.conf]] - containing all OSG sites, and
   * [[http://goc.grid-support.ac.uk/gridsite/bdii/BDII/www/bdii-lcg.conf][bdii-lcg.conf]] - containing all certified, production LCG sites (OSG sites are not included).
Generation script also 
[[http://goc.grid-support.ac.uk/gridsite/bdii/BDII/conf/bdii-additional.conf][adds]] and 
[[http://goc.grid-support.ac.uk/gridsite/bdii/BDII/conf/bdii-exclude.conf][excludes]]
some sites from the list using static files from
the [[https://goc.grid-support.ac.uk/gridsite/bdii/BDII/conf/][conf]] directory.

Logs are available in the [[https://goc.grid-support.ac.uk/gridsite/bdii/BDII/log/][log]]
directory. If the generation fails for some reason, old version of the list is not overwritten
and continues to be used.

Another cron job (maintained by Laurence Field) downloads the URI list
and makes it available on the [[http://grid-deployment.web.cern.ch/grid-deployment/gis/lcg2-bdii/dteam/lcg2-all-sites.conf][central location]].
This location is used for historical reasons (it used to contain a manually created
list of grid sites).

---++ Maintenance
The source code for the bdiiconf-gen.pl script is available in 
[[http://isscvs.cern.ch:8180/cgi-bin/cvsweb.cgi/if-ce-list/BDII/bin/?cvsroot=lcgware][CVS]].

The rest of the files (config, cron) are available only on gridsite.

*NOTE*: Since gridsite uses certificate authentication and authorisation
you need to have your certificate loaded into the browser and your certificate
subject listed in the appropriate .gacl file on the server. Otherwise you
get "403 Forbidden" error.
