Considerations for Service Component Architecture support in servers and clusters

Servers and clusters can support Service Component Architecture (SCA) applications, application destinations, or both.

SCA applications (also called service applications) require the use of one or more of the automatically created service integration buses. Each application uses a set of messaging resources, which are called destinations. These destinations require configured messaging engines, and they can be hosted on the same server or cluster as the application or on a remote server or cluster. Messaging engines typically use database data sources; note that a file store can be used in place of a database data source in a stand-alone server profile if that option was selected during profile creation.

By default, new servers and clusters in a network deployment or managed node environment are not configured to host SCA applications and their destinations.
Note: A stand-alone server has SCA support automatically configured. You cannot disable this configuration.
To enable this support, use the Service Component Architecture page in the administrative console. For servers, ensure that the application class-loader policy is set to Multiple.
Before enabling SCA support for a server or cluster in a network deployment or managed node environment, determine which of the following possible configurations you want to implement: Refer to the planning topics to help you decide which configuration is appropriate for your environment.
