Scheduled Batch jobs error : ora-01031 insufficient privileges

Question

I have created a batch job that runs my database backups on a windows 2000 server. This job works perfect from the command line with the following syntax:
coldbackup.bat PROD
I have tried to schedule this backup to run every evening as follows:
at 01:00 /every:M,T,W,Th,F,S C:\coldbackup.bat PROD
The batch job does run every morning but generates an error when trying to shutdown the database. The error is ora-01031 insufficient privileges and seems to be related to the 'connect / as sysdba' command. The job has been scheduled using the local 'Administrator' user, which have been added to the ORA_DBA group.
I have thought of one solution and that entails hard-coding the username and password into the script, but that creates a security risk.
Can someone explain this behaviour and possible provide a good solution.
Thank you

Answer 1

Solution: Yes, I have found the solution to my problem.
I was trying to schedule the batch job from the command line and in doing so the job was running in a 'system' user.
When I scheduled the job from the control panel --> schedule tasks I was able to enter the 'run as' username and password.
