Database link creation problem

Question

localhost environment:
OS:windows 2000 server
Database:oracle 8.5
database name:orcl
remotehost environment:
OS:windows 2000 server
Database:oracle 8.5
database name:orac
These two servers in network and in the same workgroup like peer to peer.There is no concept of domain here.
Here in this environment i am getting the response from both of the servers at the time of using tnsping.
C:\>tnsping orac

Hi, I have read carefully your letter.
Firt of all, when you use 'current_user' statement you must guarantee that such users have in both databases.If users exist in both databases and the error will appear again than try create database link with the option 'PUBLIC' as follow:
CREATE PUBLIC DATABASE LINK REMOTE_CONNECT connect to scott identified by tiger using 'ORAC';
and check the creation:
SQL> COL OWNER FORMAT a10
SQL> COL USERNAME FORMAT A8 HEADING "USER"
SQL> COL DB_LINK FORMAT A30
SQL> COL HOST FORMAT A7 HEADING "SERVICE"
SQL> SELECT * FROM DBA_DB_LINKS;
OWNER DB_LINK USER SERVICE CREATED
PUBLIC REMOTE_CONNECT.US.ORACLE.COM SCOTT ORAC 17.04.06
if the error appear again than checks parameter 'open_links' for your database instance. Default is 4. Increase that number. Good luck.Let me know if something go wrong.
