Logging and Exception Management for SOA-Based Composite Applications

LINC-NIRVANA is a Fizeau interferometer for the Large Binocular Telescope (LBT). The instrument combines the two 8.4-m telescopes into one image plane. Due to the high instrumental and operational complexity of LINC-NIRVANA, a software architecture is required that enables controlling, testing and maintainance of individual instrument components (Briegel et al. 2006). Service-oriented architecture (SOA) is an architectural approach to building composite applications from reusable services. A composite application consists of functionality drawn from several different sources within an SOA. The problem is trouble-shooting composite applications. For efficient troubleshooting, operators need an end-to-end, cross-platform logging and exception handling system where the logging and exception information of every unit can be retrieved, displayed and handled.
