SOA - Using FileIOInteractionSpec Class For Copying/Moving/Deleting Large File using File Adapter

(Reference https://kr.forums.oracle.com/forums/thread.jspa?threadID=904506)

If you need to copy/move/delete a big file, you have to use the follow configuration manually.

1. Create an inbound file adapter as you normally would. The schema is opaque, set the polling as required.
2. Create an outbound file adapter as you normally would, it doesn't really matter what xsd you use as you will modify the wsdl manually.
3. Create a XSD that will read your file. This would typically be the xsd you would use for the inbound adapter.
4. Create a  XSD that is the desired output. This would typically be the  XSD you would use for the outbound adapter.
5. Create the xslt that will map between the above 2  XSDs by selecting the BPEL project, right-click -> New -> General -> XSL Map in JDeveloper.
6. Edit the outbound file partner link wsdl, the the jca operations as the doc specifies.

<jca:binding  />
        <operation name="MoveWithXlate">
      <jca:operation
          InteractionSpec="oracle.tip.adapter.file.outbound.FileIoInteractionSpec"
          SourcePhysicalDirectory="foo1"
          SourceFileName="bar1"
          TargetPhysicalDirectory="C:\JDevOOW\jdev\FileIoOperationApps\MoveHugeFileWithXlate\out"
          TargetFileName="purchase_fixed.txt"
          SourceSchema="address-csv.xsd"  
          SourceSchemaRoot ="Root-Element"
          SourceType="native"
          TargetSchema="address-fixedLength.xsd"  
          TargetSchemaRoot ="Root-Element"
          TargetType="native"
          Xsl="addr1Toaddr2.xsl"
          Type="MOVE">
      </jca:operation>

7. Edit the outbound header in ftpAdapterOutboundHeader.wsdl
    <types>
        <schema attributeFormDefault="qualified" elementFormDefault="qualified" 
                targetNamespace="http://xmlns.oracle.com/pcbpel/adapter/file/"
                xmlns="http://www.w3.org/2001/XMLSchema" 
                xmlns:FILEAPP="http://xmlns.oracle.com/pcbpel/adapter/file/">
            <element name="OutboundFileHeaderType">
                <complexType>
                    <sequence>
                        <element name="fileName" type="string"/>
                        <element name="sourceDirectory" type="string"/>
                        <element name="sourceFileName" type="string"/>
                        <element name="targetDirectory" type="string"/>
                        <element name="targetFileName" type="string"/>                        
                    </sequence>
                </complexType>
            </element>  
        </schema>
    </types>   

8. The last trick is to have an assign between the inbound header and the outbound header partner link that copies the headers. You only need to copy the sourceDirectory and SourceGileName

    <assign name="Assign_Headers">
      <copy>
        <from variable="inboundHeader" part="inboundHeader"
              query="/ns2:InboundFileHeaderType/ns2:fileName"/>
        <to variable="outboundHeader" part="outboundHeader"
            query="/ns2:OutboundFileHeaderType/ns2:sourceFileName"/>
      </copy>
      <copy>
        <from variable="inboundHeader" part="inboundHeader"
              query="/ns2:InboundFileHeaderType/ns2:directory"/>
        <to variable="outboundHeader" part="outboundHeader"
            query="/ns2:OutboundFileHeaderType/ns2:sourceDirectory"/>
      </copy>
    </assign>

If you just want pass through, you don't need the native format set to opaque, with no XSLT

In the invocation, if you want to dynamically pass in the parameters.

<invoke name="InvokeFileMove"
    inputVariable="InvokeFileMove_MoveFile_InputVariable"
    partnerLink="MoveFileService" portType="ns1:MoveFile_ptt"
    operation="Move" bpelx:invokeAsDetail="no">
    <bpelx:inputProperty name="jca.file.SourceDirectory" variable="inputDirectory"/>

    <bpelx:inputProperty name="jca.file.SourceFileName" variable="inputFileName"/>
    <bpelx:inputProperty name="jca.file.TargetDirectory" variable="destinationDirectory"/>
    <bpelx:inputProperty name="jca.file.TargetFileName" variable="inputFileName"/>
</invoke>
