Compiling data transformation maps

A data transformation map needs to be compiled into a map control string before the translator component of WebSphere Partner Gateway can perform translations related to the map.

The following steps describe how to compile a data transformation map.

  1. Open the Data Transformation Maps list window by clicking the Mapping button on the Data Interchange Services client navigator bar, then selecting the Data Transformation Maps tab.
  2. Select one or more maps in the Data Transformation Maps list window.
  3. Click the Compile button on the toolbar, or select Compile from the Actions menu.

Note:
Alternatively, you can compile data transformation maps from the Data Transformation Map editor. From the editor, press the Compile button on the toolbar, or select Compile from the Actions menu. If a change has been made in the editor, a dialog appears asking if the change can be saved. Click OK to save the change and continue the compile process. Click the Cancel button if you do not want to save the change or compile the map.

Data Interchange Services client compiles the selected data transformation maps and displays an Execution Status window. When Data Interchange Services client is finished compiling, a message appears on the Execution Status window indicating that the compile has been completed. You can click the Cancel button on the Execution Status window to terminate the compile function.

In addition to compiling or recompiling the map, the map control string must be copied to the database accessed by the translator component of WebSphere Partner Gateway. This is commonly done using the export and import functions.

Note:
Compiling a data transformation map involves a large amount of database access. If your database is on a network, it may be preferable to move your map and document definitions to a local database and do the compile on the local database. After the compile has completed, the control string can be exported to the desired database.
