    Database Writer Process （DBWn）：1，3，4


    正确答案： D
    解析： 进程监视器进程(PMON) 在用户进程失败时执行进程恢复。PMON 负责清除数据库缓冲区高速缓存以及释放该用户进程使用的资源。例如，它重置活动事务处理表的状态，释放锁，并且从活动进程列表中删除该进程ID。PMON定期检查分派程序和服务器进程的状态，并重新启动任何已停止运行（但并非Oracle DB 故意终止）的分派程序和服务器进程。PMON 还将有关实例和分派程序进程的信息注册到网络监听程序。与SMON 一样，PMON 定期检查以查看是否需要执行；如果其它进程检测到需要该进程，也可以调用它。
