  1. Fault-Tolerant CORBA By, Srinivas Seshu

  2. Fault Tolerant CORBA (FT-CORBA) • What if one of the CORBA objects fail by crashing?

  3. FT-CORBA • Fault Tolerance is achieved through: • Object Redundancy • Fault Detection • Fault Recovery

  4. Object Redundancy • Replicas of object • May maintain an internal state (stateful/stateless) • Replica consistency has to be maintained • Object Group • Interoperable Object Group References (IOGR) . Points to either: • Object Group Member (OGM) • Gateway accessing the OGM

  5. Object Redundancy • IOGR helps clients to uniformly access stateless/stateful object groups while benefiting of replication & failure transparency.

  6. Replication Manager • Responsible for Object Redundancy • Create & Manage Object groups & object group members • Creates member references • Monitors a min. no. of members are alive

  7. Fault Management • Fault Detector • Fault Analyzer • Fault Notifier

  8. Recovery Management • Logging • Recovery

  9. Thank You
