File Splitting for Large File processing in XI using EOIO QoS.

Question

Hi
I am currently working on a scenario to split a large file (700MB) using sender file adapter "Recordset Structure" property (eg; Row, 5000). As the files are split and mapped, they are, appended to a destination file. In an example scenario a file of 700MB comes in (say with 20000 records) the destination file should have 20000 records.
To ensure no records are missed during the process through XI, EOIO, QoS is used. A trigger record is appended to the incoming file (trigger record structure is the same as the main payload recordset) using UNIX shellscript before it is read by the Sender file adapter.
XPATH conditions are evaluated in the receiver determination to eighther append the record to the main destination file or create a trigger file with only the trigger record in it.
Problem that we are faced is that the "Recordset Structure" (eg; Row, 5000) splits in the chunks of 5000 and when the remaining records of the main payload are less than 5000 (say 1300) those remaining 1300 lines get grouped up with the trigger record and written to the trigger file instead of the actual destination file.
For the sake of this forum I have a listed a sample scenario xml file representing the inbound file with the last record wih duns = "9999" as the trigger record that will be used to mark the end of the file after splitting and appending.
<?xml version="1.0" encoding="utf-8"?>

In the sender file adapter I have for test purpose changed the "Recordset structure" set as "Row,5" for this sample xml inbound file above.
I have two XPATH expressions in the receiver determination to take the last record set with the Duns = "9999" and send it to the receiver (coominication channel) to create the trigger file.
In my test case the first 5 records get appended to the correct destination file. But the last two records (6th and 7th record get sent to the receiver channel that is only supposed to take the trigger record (last record with Duns = "9999").
Destination file: (This is were all the records with "Duns NE "9999") are supposed to get appended)
<?xml version="1.0" encoding="UTF-8"?>
<R3File>
     <R3Row>
          <Duns>"001001924"</Duns>
          <Duns_Plus_4>""</Duns_Plus_4>
          <Extract_Code>"A"</Extract_Code>
     </R3Row>
     <R3Row>
          <Duns>"001001925"</Duns>
          <Duns_Plus_4>""</Duns_Plus_4>
          <Extract_Code>"A"</Extract_Code>
     </R3Row>
     <R3Row>

          <Duns_Plus_4>""</Duns_Plus_4>
          <Extract_Code>"A"</Extract_Code>
     </R3Row>
</R3File>
Trigger File:
<?xml version="1.0" encoding="UTF-8"?>
<R3File>
          <R3Row>
          <Duns>"001001929"</Duns>
          <Duns_Plus_4>""</Duns_Plus_4>
          <Ccr_Extract_Code>"A"</Ccr_Extract_Code>

          <Duns_Plus_4>""</Duns_Plus_4>
          <Ccr_Extract_Code>"A"</Ccr_Extract_Code>
     </R3Row>
</R3File>
I ve tested the XPATH condition in XML Spy and that works fine. My doubts are on the property "Recordset structure" set as "Row,5".
Any suggestions on this will be very helpful.
Thanks,

Hi Debnilay,
We do have 64 bit architecture and still we have the file processing problem. Currently we are splitting the file into smaller chuncks and processsing. But we want to process as a whole file.
Thanks
