1.333 TAPE_ASYNCH_IO

If your platform supports asynchronous I/O to sequential devices, Oracle recommends that you leave this parameter set to its default. However, if the asynchronous I/O implementation is not stable, you can set TAPE_ASYNCH_IO
to false
to disable asynchronous I/O. If your platform does not support asynchronous I/O to sequential devices, this parameter has no effect.
