OIC - Exception Handling

 OIC provides two out of the box features to handle exceptions.

• Scope Handler:

Scope is one of the out of the box activity allow you to bundle a set of activities which have their own variables, Faults and event handlers. In other words, scope allow you to handle error raised in IC. It is like as try and catch block in other programming languages as java, dotnet etc. every scope activity has their own fault handlers which is treated as catch block.

• Global Fault Handler:

The Global fault handler is super catch block which handle all the errors which are not supported by scope handlers. This functionality enables you to direct business faults to the caller or apply business logic before sending faults to the error handling framework. you can add fault handling to any integration type.
