TwineBallInput node

Use the TwineBallInput node to find out how the WebSphere® Adapters nodes work.

This topic contains the following sections:

Purpose

The TwineBallInput node is provided for educational purposes and allows you to see how the WebSphere Adapters nodes work. The TwineBallInput node is a sample node with its own sample EIS. You cannot use the TwineBall nodes to connect to the external SAP, Siebel, and PeopleSoft EIS systems.

The TwineBallInput node is contained in the WebSphere Adapters drawer of the message flow node palette, and is represented in the workbench by the following icon:

Configuring the TwineBallInput node

When you have put an instance of the TwineBallInput node into a message flow, you can configure it. For more information, see Configuring a message flow node. To display its properties, either double-click the node, or right-click the node and click Properties. All mandatory properties for which you must enter a value (those that do not have a default value defined) are marked with an asterisk.

Terminals and properties

The TwineBallInput node terminals are described in the following table.

Terminal Description
Out Business object events from the adapter are sent to the Out terminal.
Failure Business objects from an adapter that are not constructed successfully in the node are sent to the Failure terminal.
Catch Business objects are sent to the Catch terminal if they cause an uncaught exception in the message flow. If the Catch terminal is not connected, the retry process is activated to handle the business object.

The following table describes the node properties. The column headed M indicates whether the property is mandatory (marked with an asterisk if you must enter a value when no default is defined); the column headed C indicates whether the property is configurable (you can change the value when you add the message flow to the bar file to deploy it).

The TwineBallInput node Description properties are described in the following table.
Property M C Default Description
Node name No No The node type, TwineBallInput. The name of the node.
Short Description No No   A brief description of the node.
Long Description No No   Text that describes the purpose of the node in the message flow.
The TwineBallInput node Basic properties are described in the following table.
Property M C Default Description
Adapter component Yes Yes   The name of the adapter component that contains configuration properties for the adapter. Either enter a name of an adapter file or click Browse to select an adapter file from the list of files that are available in referenced message set projects.
The TwineBallInput node Routing properties are described in the following table.
Property M C Default Description
Set destination list No No Selected This property specifies whether to add the method binding name to the route to label destination list. If you select this check box, the method binding name is added so that you can use a RouteToLabel node in the message flow after the TwineBallInput node.
Label prefix No No   The prefix to add to the method name when routing to label. Add a label prefix to avoid a clash of corresponding label nodes when you include multiple WebSphere Adapters input nodes in the same message flow. By default, there is no label prefix, so the method name and label name are identical.
The TwineBallInput node Input Message Parsing properties are described in the following table.
Property M C Default Description
Message domain No No DataObject The domain that is used to parse the incoming message. By default, the message that is propagated from the TwineBallInput node is in the DataObject domain. You cannot specify a different domain.
Message set Yes No   The name or identifier of the message set in which the incoming message is defined.
Message type No No   The name of the incoming message. The node detects the message type automatically. You cannot set this property.
Message format No No   The name of the physical format of the incoming message. You cannot set this property.
The TwineBallInput node Transactionality properties are described in the following table.
Property M C Default Description
Transaction mode No No Yes This property specifies how updates are handled. If you select Yes, updates are performed in a single transaction (coordinated message flows). If you select No, updates are performed independently (uncoordinated message flows).
Start of changeThe Instances properties of the TwineBallInput node are described in the following table. For a full description of these properties, refer to Configurable message flow properties.
Property M C Default Description
Additional instances pool No Yes Use Pool Associated with Message Flow The pool from which additional instances are obtained.
  • If you select Use Pool Associated with Message Flow, additional instances are obtained from the message flow value.
  • If you select Use Pool Associated with Node, additional instances are allocated from the node's additional instances based on the number specified in the Additional instances property.
Additional instances No Yes 0 The number of additional instances that the node can start if the Additional instances pool property is set to Use Pool Associated with Node. By default, no additional instances are given to the node.
End of change
The TwineBallInput node Retry properties are described in the following table.
Property M C Default Description
Retry mechanism No No Failure This property specifies how retry processing is handled when a failure is rolled back to the TwineBallInput node.
  • If you select Failure, retry processing is not performed so you cannot set the remaining properties.
  • If you select Short and long retry, retry processing is performed first at the interval that is specified by the Short retry interval property, and if that is unsuccessful, it is then performed at the interval that is specified by the Long retry interval property.
Retry threshold No Yes 0 The maximum number of times that retry processing is performed for short retry.
Short retry interval No Yes 0 The interval between short retry attempts.
Long retry interval No Yes 0 The interval between long retry attempts.
