A configuration manager federated bean is provided for each host computer
in the three-tiered management system. The configuration manager
federated bean for a host computer is contacted by federated beans that
manage each of the data services when a data service starts and stops
using a data storage volume associated with the host computer. The
configuration manager bean maintains persistent configuration information
for each data service. In one embodiment, configuration manager beans can
operate in a clustered environment where several beans store
configuration information in a single storage area. Each of the beans
implements an arbitration protocol so that only one bean writes to the
storage area at any given time.
