Handling exceptions in a uniform way is one of the critical aspects of designing business processes on the Fiorano platform. 

Using the ExceptionListener Service component

This component serves as a global exception listener that subscribes to exception messages occurring in any service component of any running event process and handles them appropriately in the error handling event process.

Figures 1 and 2 illustrate how the ExceptionListener component is configured and used in a global exception handler event process.

Configurable properties in the Exception Listener microservice CPS allow to define rules that decide the preferred peers or event processes which the flow should monitor. Refer ExceptionListener documentation for more details.
