You can use the following functions to write the results of large XSLT/XQuery operations to a temporary file in a directory system. The document is then loaded from the temporary file when needed. This eliminates the need for caching an entire document as binary XML in memory.

• ora:processXSLT

• ora:doXSLTransformForDoc

With the ora:processXSLT function, you use the properties argument to enable this functionality.

ora:processXSLT('template','input','properties'?)

You retrieve the value of this argument within your XSLT in a way similar to extracting data from XSL variables. The properties argument is an XML element of the structure shown in the example that follows. For large payload results (for example, above 10 MB), set streamResultToTempFile to yes. For small payload results in which you do not need to write results to a temporary file, leave this property set to its default value of no.

<propertiesXMLVar>
  <common:item  xmlns:common="http://schemas.oracle.com/service/bpel/common">
    <common:name>streamResultToTempFile</common:name>
    <common:value>yes</common:value>
  </common:item>
</propertiesXMLVar>

Within the XSLT, the parameters are accessible through the name of streamResultToTempFile and its value of yes.

In Oracle BPEL Process Manager, a literal assign is performed to populate the properties for ora:processXSLT('template','input','properties'?).

For more information about using this function, see processXSLT.

With the ora:doXSLTransformForDoc function, you set the name and value properties to enable this functionality.

ora:doXSLTransformForDoc('template','input','name', 'value')

With this function, the name of streamResultToTempFile and the value of yes are passed.

For more information about using the function, see doXSLTransformForDoc.
