After the successful installation of OGSA-DAI it must be registered (if this not done) as new supported storage middleware in the site using the D-Grid resource and user management portal. For more information please see here.

To integrate the OGSA-DAI installation to the D-Grid infrastructure, the following border conditions are mandatory:

  • Data resources registration in the global MDS Index,
  • A data resource per VO (including a database and a user with a password),
  • An additional expansion module to allow the management of the various VOs,
  • Connection to the user administration, to match the access arrangements with the D-Grid VO data.

These requirements can be achieved using a provided library, which contains all the necessary tools and components to enable OGSA-DAI to be used within the D-Grid reference installation. Place this file under '$GLOBUS_LOCATION/lib'.

Please see the MDS Service description.

CA-certificates
It must be ensured that all nodes except torque and NFS servers, have a current version of CA certificates available. In the D-Grid reference installation this actualization is done by the cfengine automated configuration tool.

For this you have to install the Cfengine client using the instructions here and to configure it as here.

Users/VOs
In order to enable all new users and VOs for accessing the grid services, it must be ensured that all nodes except torque and NFS server, have a current version of the passwd and group files. In the D-Grid reference installation this actualization is done by the cfengine automated configuration tool.

For this you have to install the Cfengine client using the instructions here and to configure it as here.

grid-mapfile
It must be ensured that the OGSA-DAI Frontend have a current version of the grid-mapfile available. In the D-Grid reference installation this actualization is automated by the cfengine configuration tool. For this you have to install the Cfengine client using the instructions here and to configure it as here .
