Large Document Files

To process a large B2B Data Exchange document, complete the following steps:

Verify that B2B Data Exchange, Apache Tomcat, and PowerCenter, can use the same file path to access the document store directory you set during the B2B Data Exchange installation.

In B2B Data Exchange Operation Console, verify that the value of the system property document.store.folder is the document store directory you set during installation.

When creating a file-receipt endpoint using the Endpoint screen, turn on the Pass by Reference flag on. For more information, see the

B2B Data Exchange Operator Guide

In the PowerCenter Designer, when you build a mapping to process the document, include a JMS source and target and call the B2B Data Exchange transformations and the Unstructured Data transformation.

Configure the following PowerCenter objects:

JMS source definition.
Add the DXDataByReference property to the JMS properties in the source and target definitions. If the JMS message contains a document reference, the DXDataByReference property is true.

DX_Get_Document_File_Path transformation.
Use this transformation convert the document reference in the JMS source to a file path that can be used to access the associated file in the document store.

DX_Generate_Temporary_File transformation.
Use this transformation to generate an output file for the Unstructured Data transformation.

Unstructured Data transformation.
Call this transformation to use the

Data Transformation

service to transform the document to the required format. You can also use the Unstructured Data transformation to split a large document.

DX_Aggregate transformation.
If you split a large document, call this transformation to combine the transformed data segments into one document.

API calls: createDocument and addEventDocument.
Use these calls to attach the output file to an event as a new target document.

JMS target definitions.
Send the new document to the JMS target. Add the DXDataByReference property to the JMS properties in the target definition. If the JMS message contains a document reference, set the DXDataByReference property to true.

In B2B Data Exchange Operation Console, after you run the workflow, verify that an event has been created for the large document processed. You can view the source document in the Source Data section of the event details page and the target document in the Target Data section of the event details page.
