IOGR Tool

A tool for building and managing FT-CORBA compliant IOGRs. This tool should be useful for anyone that is going to implement a FT-CORBA compliant Infrastructure.

Interceptors

In the context of the IRL Project, a fundamental role is accomplished by CORBA Portable Interceptors.

CORBA Request Portable Interceptors allow to intercept messages flowing between clients and servers and to modify messages as well as the invocation path, even on the basis of the information contained in the messages (with some limitation). In particular, Portable Interceptors are a useful tool in the contex of the IRL Project to let a CORBA client holding an Interoperable Object Group Reference invoke an object group and obtain replication and failure transparency. In IRL, this task is accomplished in a transparent way by the Outgoing Request GateWay (ORGW, see also the Architecture page).

o evaluate Portable Interceptor's performances on Java ORBs, we run a wide set of experiments on three distinct Java ORBs, namely JacORB, ORBacus for Java, and Orbix 2000.
