Creating a DSN in Widows XP for an Oracle Database

I have a:
Username
Password
IP Address
SID

For a database I would like to reverse engineer in Visio.  It seems as though I have to set up a DSN for this first in the Control Panel.   How do I do this?

What do I fill in for:
Data Source Name
Description
User Name=this I know
Server???


Please let me know!

There is a problem with the Oracle client setup.

from a command prompt try and post results:
tnsping <dbalias>

where <dbalias> is the alias name used for Server in the DSN entry.

for visio one can use odbc or microsodt driver for oracle for connection to the database .

I recommend u to use third party tools like erwin for doing reverse engg .,

I think once u create DSN , do test connection and check all the credentials for connection making .

or we thing u can do is generate oracle object script and do changes to script as of to visio.
