connect from Oracle to MS SQL Server

I want to Connect from Oracle to MS SQL Server with a connection string to pass location (IP) / username / Password and SQL Database !
After searching the internet i found using a ODBC connection, which must created before and then telling the listener this ODBC connection.
Problem is, that i want to be variable and the user should give his accounting data into my oracle application.
How could this implemented ?

Thanks in advance.
