In order to increase flexibility and reduce complexity, the use of distributed platforms such as CORBA for building complex distributed systems is growing significantly. Although CORBA platforms provide a better support than conventional RPC mechanisms for ...
Issues in Building a Parallel Java Virtual Machine on Cenju-3/DE X. Defago and A. Konagaya This paper describes how a Java virtual machine can use the inherent concurrency of Java programs on a massively parallel processor machine (MPP) like NEC Cenju-3. A ...
One of the fundamental differences between a centralized system and a distributed one is the notion of partial failures. The ability to efficiently and accurately detect failures is a key element underlying reliable distributed computing. In current distri ...
The CORBA Object Group Service (OGS) is a new CORBA service that provides support for fault-tolerance through the replication of CORBA objects. In this paper, we present several optimization techniques that are used to improve the performance of OGS. For e ...
The Swiss Exchange system (SWX system) was the first stock exchange system in service to be fully computerised. For high availability, the trading system is built as a replicated service based on Isis. For portability reasons, the SWX team has considered b ...
This paper presents the semi-passive replication technique -- a variant of passive replication -- that can be implemented in the asynchronous system model without requiring a membership service to agree on a primary. Passive replication is a popular replic ...
This paper presents a pragmatic way to build a Reliable CORBA Event Service. Our approach is pragmatic in the sense that, rather than building the service from scratch, we show how to obtain it, through a simple transformation, from any standard (unreliabl ...
This paper presents the semi-passive replication technique -- a variant of passive replication -- that can be implemented in the asynchronous system model without requiring agreement on a primary (usually done using a membership service). Passive replicati ...

Replication is a key mechanism for developing fault-tolerant and highly available applications. In this paper, we present a replication framework for replicating CORBA objects, that combines the active and passive replication techniques. We show how we hav ...
