SCA system bus

The SCA system bus is a service integration bus used to host queue destinations for SCA modules. The SCA run time, which supports mediation modules, uses queue destinations on the system bus as an infrastructure to support asynchronous interactions between components and modules.

The system bus is automatically created when you create a deployment environment or when you configure a server or cluster to support SCA applications. The system bus provides a scope within which resources, such as queue destinations, are configured for mediation modules and interaction endpoints. The bus enables message routing between endpoints. You can specify the quality of service for the bus, including priority and reliability.

The bus name is SCA.SYSTEM.busID.Bus. The authentication alias used for securing this bus is SCA_Auth_Alias.
