Use the Service Component Architecture page to configure a cluster or server to support WebSphere® Service Component Architecture (SCA) applications. Service applications are those that require the use of one or more of the following buses: SCA.APPLICATION.CellName.Bus, SCA.SYSTEM.CellName.Bus, or BPC.CellName.Bus.
By default, new servers and clusters do not have SCA support configured.
Links marked (online) require access to the Internet. Each link launches a search for the topic in the online information center. When search results are listed, select the topic that corresponds best to your configuration.

Use the Enable the service component architecture check box to specify that SCA applications can be deployed to the current cluster or server.
By default, this option is cleared for a new cluster or server.
Select this radio button to specify that you want to host SCA applications on the local cluster or server while hosting the required messaging engines and destinations on a remote cluster or server.
Select this radio button to specify that you want to host SCA applications and their required messaging engines and destinations on the current cluster or server. When you select the Configure a destination location locally radio button, the System Bus Member and Application Bus Member panels are available; they contain additional fields needed to complete the configuration.
Specifies the properties of the data source used by the SCA system bus. This panel is active whenever you are creating a new SCA configuration for the cluster or server.
Select this checkbox if you want to use the default data source for the server or cluster. The default data source uses the embedded database on the local file system.
This field is optional and is cleared by default when you are creating a new SCA configuration.
Specify the name of the data source you want to use for the server or cluster. You can use the drop-down menu to select an existing data source or click New to define a new data source.
If you want to make changes to the selected data source before completing your SCA configuration, click the Edit button next to the field to access the data source configuration page.
This field is available only if you are creating a new SCA configuration and have not selected Use Default Data Store.
Use the Schema field to specify the name of the database schema that contains the tables for the system bus data source.
This field is available only if you are creating a new SCA configuration and have not selected Use Default Data Store. It is required if you are creating or using a data source with a database that supports schema names.

Use the Create tables check box to specify that the messaging engine must create the database tables for the data sources. If this option is not selected, the administrator must create the database tables manually.
This field is available only if you are creating a new SCA configuration and have not selected Use Default Data Store. It is optional.
Specifies the properties of the data source used by the SCA application bus. This panel is active whenever you are creating a new SCA configuration for the cluster or server and when you are adding a new application bus configuration to an existing SCA configuration.
Select this check box to specify that you want to configure the SCA application bus with support for WebSphere Business Integration Adapters.
Select this checkbox if you want to use the default data source for the server or cluster. The default data source uses the embedded database on the local file system.
