Overview of selector components

As businesses change, the business processes that drive them must change, too. Some of those changes may require that certain processes return different results than as originally designed without changing the design of the process. The selector component provides the framework for that flexibility.

Selector components provide a single interface to a service that may change results based on certain criteria. The selector component includes an interface and a selector table. Based on the criteria, the selector table determines which component (named the target component) processes the request. The server returns the processing result provided by a target component to the client.

When building a business process, the solution architect identifies the need for a selector component and defines the interface and selector table that the selector component uses to complete processing. The tasks involved in developing a selector component are described in the IBM Integration Designer Information Center.

Administering a selector component consists of tasks related to the selector component or tasks related to the selector table.

Restriction: To access any of the selector component pages, you must supply a user ID when you log in to the administrative console. If you are logged in without a user ID, you will receive a warning to log out and log back in with a valid user ID.

• Displaying selector components
  Displaying selector components is the first step in administering selector components. From the display you can export any or all of the selector components or display the selector tables which make up the selector components.
• Displaying selector tables
  Displaying selector tables is the first step in administering the tables. The resulting display is a list of target components from which you can alter the processing criteria, change the target component that runs for a specific criterion, add a new target component or delete a target component from the table, thereby removing a criterion.
• Changing target components
  Changing target components allows you to alter selector component processing by either changing the selection criteria for a specific target component, changing the target component for a selection criteria, or changing both the selection criteria and the target component.
• Adding target components
  Add a target component when you need additional processing for a different selection criterion than currently exists in the selector table.
• Delete target components
  Deleting target components alters selector component processing by removing the entry in the selector table for a specific selection criterion.
• Export selector components using the administrative console
  Export selector components when you have made changes to the selector tables. This will create a file that you can import into your development environment, thereby keeping the development artifacts synchronized with the actual production system artifacts.
• Importing selector components using the administrative console
  Import selectors in order to update installed selector components without reinstalling an application.
