Using XSLT Transformations on Large Payloads (For Oracle Mediator)

Until 11g Release 1 11.1.1.3, for XSLT operations in Oracle Mediator, the result was cached into memory as a whole document in binary XML format. For large document processing, this caused out-of-memory errors. Starting with 11g Release 1 11.1.1.4, the streamResultToTempFile property was added. This property enables XSLT results to be streamed to a temporary file and then loaded from the temporary file. Set streamResultToTempFile to yes when processing large payloads using XSLT. The default value is no.

Note:

This property is recommended only for processing large payloads. Enabling this property could reduce performance for normal payloads.

To configure large XML documents to be processed using XSLT:

  1. Create an Oracle SOA Suite project with an Oracle Mediator component.
  2. Open the composite.xml file for the project in Source view.
  3. In the composite.xml file, scroll to the component element that defines the Oracle Mediator component to process large XML documents, and add the streamResultToTempFile property. Set the property to yes as shown below.
    <component name="Mediator1">
   <implementation.mediator src="Mediator1.mplan"/>
   <property name="streamResultToTempFile">yes</property>
</component>
  4. Save and close the file.
