database link question

Hi

if i have 2 schemas in database1(globalname : db1.oracle.com)
User1 & user2

& there is another schema in database2(globalname : db2.oracle.com)
testuser


I am pulling data from database1(user1 & user2) to database2 (testuser)
so i am using database links

ideally database link naming convention mandates that we have the global name of the
database we want to connect to as the name of the database link

so in my case in database2 - testuser schema i create link like this
link name - db1.oracle.com connect to user1 identified by --- using '---'

it works fine

now i want a link to user2 schema in database 1
What name should i use for the link . i cant use db1.oracle.com as it is
already pointing to user1 schema


Kindly respond

Why do u wana create another db link, when you have one..cant u select data of user2 from user1? if not give select privis on the table of user2 to user1 on db1.

Abhay.
