We have 2 database which have DB links between. The user in both
database have the same name. We cannot figure out how to grant the
privileges.

Your database link connects through a user in the target database.
Grants should be done IN the target database by an account with the
privileges to do so. You can not grant over the link.

Right, but take this:

DB1
------
USER: JOHN
TABLE: TAB1

DB2
------
USER: JOHN
TABLE: TAB1

I cannot grant a privilege to myself. I mean, the user names are the
same, and I am having trouble with that part, unless I am missing
something.

When you attach to the dblink, you login as that user. So you don't
need to grant anything to that user. The fact that users in two
databases are named the same is irrelevant. What are you trying to
accomplish that isn't working, besides this granting?

JG has nailed the issue on the head. If the link is defined without a
fixed username and password in the link then it would be known as a
current user link and Oracle would expect the same username to be
defined in the remote database with the same password. In other words
Oracle would expect the usernames to be the same user with an account
on both databases.

When a fixed user link is used then every connection is as the remote
database username contained in the link.

There are also global links, which use LDAP security, and these are
basically just another form of current user link where the current
user is LDAP authenicated to the database.
