A Implementação de uma Arquitetura de Suporte à Alta Disponibilidade de Objetos
Abstract
This paper presents the implementation of an architecture whose goal is the high availability provision to distributed objects with transparency and flexibility. This architecture is based on computational reflection concept and its implementation was made using a meta-object protocol. The architecture uses meta-objects to incorporate the availability level desired to the objects as long as the access to these objects. The object localization is completely transparent to the clients, where it can be seen as local and not remote. We also present early experimental results showing the method call overhead when incorporating availability in objects.
