File listener is unable to move files

SA-53567

Summary



File listener is unable to move files, during processing, from a source location to a completed folder.


Error Messages



Not Applicable


Steps to Reproduce

  1. Place a file in the source location.
  2. Open the file manually and acquire the lock from the Operating System level.


Root Cause



The File Listener processed files in the source location. After processing, the file moved to either the Completed or the Work subdirectory depending on the File Listener configuration and whether the file processed correctly. During processing, the file is read and processed multiple times if it was opened by the Operating System (specifically Linux). However, it cannot be moved until the Operating system released the lock.

Resolution



Perform the following local-change when copying files to these directories:
  • Do not open a file while it is being processed.
  • Do not copy a new file over an old file while it is being processed.
  • Use a different file name every time (for example, append a time stamp to the file name before copying it).
