Access is denied when importing data from Oracle 11g for configuring Data source

Hi,

I am trying to install Cognos 10 on my windows 7 machine for learning purpose.

it is running on localhost. (http://localhost/cognos). and i have installed Oracle 11g.

now i am configuring Data source and sample configuration.

when i run a windows batch file named setupGSDB which is in under package of sample Oracle data source in Cognos.

this open a cmd prompt. it asks for oracle instance, login as sysdba to import the data for GoSales sample data.

i gave oracle instance: orcl, admin user name & password: system as sysdba

it shows:
