Description
This paper describes challenging requirements on the configuration service. It
presents the status of the implementation and testing one year before the
start of the ATLAS experiment at CERN providing details of:
- capabilities of underlying OKS* object manager to store and to archive
configuration descriptions, it's user and programming interfaces;
- the organization of configuration descriptions for different types of data taking
runs and combinations or participating sub-detectors;
- the scalable architecture to support simultaneous access to the service by
thousands of processes during the online configuration stage of ATLAS;
- the results of large scale tests performed on the configuration service and
experience of it's usage during test beam and technical runs.
The paper also presents pro and cons of the chosen object-oriented
implementation comparing with solutions based on pure relational database
technologies, and explains why after several years of usage we continue with it.
