Composition unit settings for SCA composites

Use this page to view composition unit settings and to change the properties of a Service Component Architecture (SCA) composite.

To view this administrative console page, click Applications > Application Types > Business-level applications > application_name > deployed_asset_name. The deployed asset is a composition unit of the business-level application.

To view this page, your composition unit must support SCA.

Name

Specifies a logical name for the composition unit. You cannot change the name on this page.

Description

Specifies a description for the composition unit.

Backing identifier

Specifies a unique identifier for a composition unit that is registered in the application management domain.

The identifier has the format: WebSphere:unit_typename=unit_name. For example, for the MyApp.jar asset, the backing identifier might be WebSphere:assetname=MyApp.jar.

You cannot change the identifier on this page.

Data type String
Units Configuration unit identifier
Starting weight

Specifies the order in which composition units are started when the server starts. The starting weight is like the startup order. The composition unit with the lowest starting weight is started first.

The value that you set for Starting weight determines the importance or weight of a composition unit within the business level application. For example, for the most important composition unit within a business-level application, specify 1 for Starting weight. For the next most important composition unit within the business-level application, specify 2 for Starting weight, and so on.

Data type Integer
Default 1
Range 0 to 2147483647
Start on distribution

Specifies whether to start the composition unit when the product distributes the composition unit to other locations.

The default is not to start the composition unit.

This setting applies to asset or shared library composition units. This setting does not apply when the composition unit is a business-level application.

Data type Boolean
Default false
Recycle behavior on update

Specifies whether the product restarts the composition unit after the composition unit is updated.

The default is to restart the composition unit after partial updating of the composition unit.

This setting applies to asset or shared library composition units. This setting does not apply when the composition unit is a business-level application.

Table 1. Option descriptions
Option Description
ALL Restarts the composition unit after the entire composition unit is updated
DEFAULT Restarts the composition unit after part of the composition unit is updated
NONE Does not restart the composition unit after the composition unit is updated
Target mapping

Specifies one or more current targets for the composition unit.

To change the existing deployment targets, click Modify Targets and select different deployment targets from the list of available clusters and servers.
