Creating a message map file from a DataUpdate node

You can use a DataUpdate node to create mappings to update existing data in a database from a message, another database or both.

Before creating a message map file, ensure you do the following:
  1. Create a message flow project
  2. Create a message flow
  3. Define message flow content that includes a DataUpdate node
  4. Create a database definition

To create a message map (.msgmap) file from a DataUpdate node:

  1. From the Broker Application Development perspective, open your message flow, right-click your DataUpdate node, and click Open Map. The New Message Map for Data Update Node wizard opens.
  2. Select the combination of Messages, Data Sources or both that you want to use as sources for your map from Select map sources.

    If you cannot find the Messages or Data Sources that you expect, select the Show all resources in workspace check box.

  3. From the Select map targets pane, select the tables under Table Updates in which you want to update data. The tables that you select are added to the new message map as targets.
  4. Select OK to create the new message map. The Message Mapping editor opens with the selected sources and targets.
After you have created a message map file, you can now configure the message mappings.
