    According to Oracle:

    Initialization Parameters: Multiple Database Writers

    On UNIX, you can specify more than one database writer process with initialization parameter DB_WRITERS. Multiple database writers can help, for example, when a UNIX port does not support asynchronous I/O.

    DB_WRITERS is supported but typically unnecessary on Windows, which has its own asynchronous I/O capabilities.
