Database link without SQL*NET string

You can create a database link without having a SQL*NET string in your tnsnames.ora file. This is beneficial when you use a remote database for one time only or you have a different client (eg, 8.0 vs. 7.3). This tip has been tested on Oracle 8.0.5. It may also work with 8i or other versions that use SQL*NET.

(PORT = 1521))) 
(CONNECT_DATA = (SID = DIS)))'       <---- SID OF DB
