No matter how carefully a distributed application has been specified, implemented, and tested, its network objects will crash unexpectedly due to power outages, human lapses, hardware faults, and software bugs. The OMG CORBA standard is becoming popular for interoperability and extensibility. However, fault-tolerance and reliability have not adequately been addressed yet. This paper describes the design and implementation of Piranha --- a CORBA-based, graphical availability management and application monitoring tool. Piranha is unique in that it can be used to increase the availability of many CORBA applications, without complicating their development.
