在oracle 11g中安排备份恢复

Question

我正在尝试将备份恢复安排到我的oracle 11g数据库，我将上述脚本与windows任务调度程序一起使用：

rman target/
run
{
shutdown immediate;
startup mount;
backup incremental level 0 database plus archivelog delete input;
backup archivelog all delete input;
delete force noprompt obsolete;
backup current controlfile spfile;
alter database open;
}

调度程序在指定时间启动，但备份未启动。当我通过：rman执行备份时它工作正常。

========我从寡妇调度任务中获得了什么===========

=========我应该得到什么（没有任务安排，它工作正常）===

显然，运行脚本无效：

run
{
shutdown immediate;
startup mount;
backup incremental level 0 database plus archivelog delete input;
backup archivelog all delete input;
delete force noprompt obsolete;
backup current controlfile spfile;
alter database open;
}
