        Hi there,

        There seems to be a problem when using the "use temporary file while writing"-flag of the FILE-adapter of BTS2006 with UNC-paths.

        I'm trying to write a file to a network drive. The error message I get, when using a static port is:

        The adapter failed to transmit message going to send port "SendPort2" with URL "\\Tblbiz01\Dynamic-Filedrop\OUT2\%MessageID%.xml". It will be retransmitted after the retry interval specified for this Send Port. Details:"The FILE send adapter cannot open file \\Tblbiz01\Dynamic-Filedrop\OUT2\{5ACF2762-0B57-467D-9354-BF841CE018F2}.xml for writing. Details: (something like) The process cannot access the file as it is being used by another process.

        I also tried using a dynamic send port. In that case, the error message is:

        A message sent to adapter "FILE" on send port "SendPort_Dynamic_out" with URI "file://\\tblbiz01\Dynamic-Filedrop\OUT1\test1_temp.xml" is suspended. Error details: The FILE send adapter cannot open file \\tblbiz01\Dynamic-Filedrop\OUT1\test1_temp.xml for writing. Details: (something like) The process cannot access the file as it is being used by another process.

        It doesn't seem to be a permission problem because everything works fine if I leave the checkbox "use temporary file while writing" unchecked.

        Also, the problem doesn't occur when I use local drives (i.e.: D:\mydir\mydoc.xml). It only happens when a UNC-path (i.e. \\myserver\mydri\mydoc.xml) is given.

        Suggestions are most welcome as I don't really want to start writing a custom adapter for this.

        Cheers,

        JB

          Hi JB,

          I have looked into this issue. I haven't been able to solve this issue yet as it seem like a BUG in File adapter (Not sure so far). But i can explain what’s going wrong.

          Biztalk does create a Temp file Named: "[Your complete file name].BTS-WIP"

          When it finishes writing the temp file to the specified location, it tries to rename the file to "[Your complete file name]". But unfortunately the file is already open by the existing stream and Biztalk gets the "Sharing Violation" error. Upon getting the error it deletes the "[Your complete file name].BTS-WIP" file.

          You can test this your self as well. Just remove the delete permission from the Folder where Biztalk tries to create the File. Run your process and see that the "[Your complete file name].BTS-WIP" is still there as the Biztalk process was not given permission to delete the file.

          I have been trying to resolve this issue but no luck so far. But I thought to share my findings with you, so you can look into this as well.

          Look through these:

          Hopefully there will be any other solution without a need to create a custom adapter. Keep the post updated if you find any thing.

          Cheers
