I have set database name as scott/tiger .

I have following queries

1) what need to be done if i need to call that shell script in another database .
Means everytime its not posible to change the database name ..

is there any automatic process for it

re: sqlloader shell script

If you want to change the database name on the fly then declare a variable and use it in the command.
The variable will be initialized either from command prompt or from a file

Hope i am clear
