If running FastExport in a UNIX operating system, be aware of the UNIX signals used by FastExport. The FastExport UNIX signals in any program module or routine cannot be used with FastExport. Doing so causes an error in FastExport.

FastExport uses the following UNIX signals:

  • SIGINT (interrupt signal)
  • SIGQUIT (quit signal)
  • SIGTERM (terminate signal)
    Signals are predefined messages sent between two UNIX processes to communicate the occurrence of unexpected external events, or exceptions. Aborting a FastExport session while FastExport is in the middle of processing a job is an example of an exception. In this scenario, FastExport uses the UNIX signals to trap the abort command, disconnect all sessions, do any necessary cleanup, and then terminate in an orderly manner.
