An Infrastructure for Adaptive Fault Tolerance on FT-CORBA
Lau Cheuk Lung, Fábio Favarim, G.T. Santos, Miguel Pupo Correia · 2006
The fault tolerance provided by FT-CORBA is basically static, that is, once the fault tolerance properties of a group of replicated processes are defined, they cannot be modified in runtime. A support for dynamic reconfiguration of the replication would be highly advantageous since it would allow the implementation of mechanisms for adaptive fault tolerance, enabling FT-CORBA to adapt to the changes that can occur in the execution environment. In this paper, we propose a set of extensions to the FT-CORBA infrastructure in the form of interfaces and object service implementations, enabling it to support dynamic reconfiguration of the replication.
