Shutdown from OS Batch File (NT40), and Backup

Hello!
[Quoted] [Quoted] Does anyone know how to make an OS Batchjob to shutdown [Quoted] the DB before backup, and then start the DB after Backup. I am using Cheyenne Arcserve backup SW. Cheyenne has the possibility to do 'Before backup job' and 'After Backup job' in the backup task.
This shutdown and startup has to go without any user action. This is a fullvolum backup job of all partitions and all disks.
Perhaps even an export before backup starts.

Any tips/Ideas

Config: 	Oracle 7.3.3 (NT)
		Enterprise Manager 1.4
		Win NT 4.0 Server
		12 GB Disks
