I have downloaded ds_windows_x86 disk1 and disk 2.
I am installing oracle on windows from these two files .
How everever while installing they do not ask for database and password and the installation is completed successfully .
After installation I give scoot and tiger as database name and password .
The it is giving error Tns 12560 tns protocol error
Pl post a link from where you downloaded this software. Pl also post exact OS version. As Paul noted, if this is Developer software, it does not come with a database - you will have to install database software separately and create a database.
For an alternate approach, pl see Installing Oracle to learn Oracle Forms and Oracle Reports?
