Message Exchange Patterns that Integration Server Supports
Each operation of a web service uses a SOAP Message Exchange Pattern (MEP), which is a template that defines how the operation exchanges SOAP messages. Integration Server supports the following MEP types:
In-Out MEP, a request-response pattern where a consumer sends a request and expects a SOAP response from the provider.
In-Only MEP, a one-way message exchange where the consumer sends a request and expects no SOAP response from the provider.
Robust In-Only MEP, a reliable one-way message exchange where the consumer sends a request and expects no SOAP response from the provider if the operation is successful, but expects a SOAP fault if an exception occurs.
