Service Introduction

LHCb, which is already using the AMGA service in production-mode through a VOBOX, wants to contribute to the test of the gLite packaging, envisaging a future standard distribution of the service in production (at CERN).

CERN_PPS will install an AMGA service using the gLite distribution.

Use cases

The AMGA instance in PPS will be used by the VO for development purposes. It will be accessed by a development instance of the LHCb BookKeeping server (BK) and connected at the back-end with a "development" version of the schema

LHCb currently uses AMGA clients installed directly on the BookKeeping server. The possibility for LHCb to switch and use instead a PPS distribution (on AFS) of the clients will be analysed.

As far as people in the room can tell, in the plans of the LHCb VO, there are no other foreseen future deployment models than a central (critical) service to be run at CERN.

LHCb does not use (and is not planning to use in the short term) the BDII to retrieve the end points of the AMGA server

General Agreement on Service Level and Conditions

Metrics

The main goal of the activity is to verify that the package is fitting with FIO requirements for a deployment in production

The success of the pilot is defined by the acceptance of the service by CERN FIO

There are currently several AMGA servers running worldwide (HEC has got ~50 instances running). In that respect the goal of deployability of the service to a small sites has to be cared. These non-HEPscenarios will be followed-up by PPS with the help of AMGA deployment experts but with lower priority than the main goal. This issues will likely not concern, however, the Oracle packaging

Timeline

The installation at CERN_PPS will start as soon as the hardware is available and completed within one week (unless blocking problems in the distribution are found)

The availability of the service will be conveniently notified to LHCb

After 4 weeks of usage (or upon success of the pilot) an assessment meeting will be held and a decision made about the follow-up (including decision to prolongate the testing time). Eventually guidelines for the deployment in production will be drafted
