Impact of using DBLINK to extract data from remote server
I will appreciate if you pls tell me ...
1.What is the impact of using DBLink to extract data from a remote server?
2. How does it differ from DBLink extraction,from performance view to extract data using direct username and password with Service/Tnsnames?
3. Do you have any good link that will discuss about the same?
