Abdul, You are hitting one of the more common problems with db links and domain names. The "us.oracle.com" at the end of the name is the symptom.
To use the link, append the domain (i.e., select * from [EMAIL PROTECTED]). To drop the link, try "drop public database link my_link.us.oracle.com". That should get rid of it. To see where your problem is coming from: sqlplus internal show parameter domain select * from global_name; The output from these two commands should show you that your domain has been set to "us.oracle.com". This domain is only truly proper for Oracle internal databases. I suspect it gets used accidentally quite often. I've been able to fix this problem in the past but can't remember exactly what I had to do. Seems like I changed the db_domain parameter in the init.ora file and also had to change the database name using an alter database command (or something like that) then I had to drop and recreate all my db links -- long time ago and far away when Enron was still walking the earth.....

What can this mean? -----Original Message----- Sent: Monday, August 26, 2002 6:33 AM To: Multiple recipients of list ORACLE-L Thank you Edward, As suggested, I have tried the following command (since PUBLIC is required) CREATE PUBLIC DATABASE LINK my_link CONNECT TO UserA1 IDENTIFIED BY passwordA USING 'abc' The Server B from where I am issuing this command, connects to the Server A using the same connect string 'abc'. After this connection I am able to view tables, data etc. But the command describe table1@my_link seems to be liking the error ora-02019: connection description for remote database not found. The view all_db_links lists this link but appends us.oracle.com to my_link under db_link column. Any more suggestions For dropping the link, I was missing "PUBLIC" keyword Aleem -----Original Message----- Sent: Monday, August 26, 2002 4:03 PM To: Multiple recipients of list ORACLE-L Subject: RE: Problem in creating DB Link Hi Aleem, Just try to create a simple link without PUBLIC and SHARED keywords if you don't really need them. Login as user B and issue the following command: CREATE DATABASE LINK mydblink CONNECT TO userA IDENTIFIED BY password_of_userA USING 'abc'; If you get ORA-02019 then check if the correct service name (abc in that case) exists in your tnsnames.ora on server B. You can use TNSPING abc to ensure that your service name points remote db properly.
