That is the problem. It is not documented. I think that is the reason why
we went down that path of designing our application. I have an email from
oracle rep (RAC team member). He confirmed that with Oracle product
development.

You can create as many dblinks as you want provided
that the dblink name is the same as the global name of the database you connect
to.
In your example:
Create public database link HR connect to HR identified

Hi Jonathan,
thanks for your reply.
The deal is that you can't use DB1@HR and DB1@SHIP if you are using global_names=true; the link name has to be the same than the global database name.
But what do

select * from global_name@db1@shipping;

Hello,
Oracle 8.1.6 on Solaris 2.7.
Can any one provide me with information or a link regarding
performance of views across database links?
I am thinking of the case where instance A has a view defined
as SELECT FLD1,FLD2,... FROM TABLE_T1@DBLINK.
Consider the case when a view such as this is
Bill,
I too would love to hear from better experts than me.
I also have implemented queries using db links.
In my rudimentary testing, I found that you need to create the view on the
remote machine to get any decent kind of performance, and then access that
view thru the db link. My guess
kinda sorta in link$ (including the in the clear password)

This will only give you the public database links. You will also need to
log in as the schema that owns the private database link, if that's the
case, and look at user_db_links.

Good point. I have tested the following to capture both PUBLIC and private
db links.
set linesize 500;
set pagesize 1000;
column owner format a20;
column link_name format a20;
column userid format a20;
column host format a20;
column password format a20;
SELECT u.name owner, l.name link_name
Alex,
Yes, the connection remains open unless it is
explicitly closed (see Note: 1034343.6).
The session also takes out a lock on the local RBS
(see Note:74811.1) as this could be part of a
distributed transaction. If this is a long running
query this can lead to abnormal growth in the RBS
If I query table in the remote database using database link does user in the
remote database which is referenced in the database link create session in
the remote database and if not could somebody explain how remote query is
executed.

P.S. I know that I could try it myself but I
Yes, it creates a session. If you want to do a(n) SQL trace, you can do a
SELECT 'x' FROM dual@remote_site, find the session at the remote site and
turn on the trace, then run your next query.

Also, you don't want to join remote tables together. Create a join-view on
the remote database instead.
