TAPE_ASYNCH_IO
controls whether I/O to sequential devices (for example, backup or restore of Oracle data to or from tape) is asynchronous--that is, whether parallel server processes can overlap I/O requests with CPU processing during table scans. If your platform supports asynchronous I/O to sequential devices, Oracle Corporation 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.
