ODBCREN - ODBC источник в SYSTEM DSN на другую не-Oracle БД.

Вот sqlnet.ora
NAMES.DEFAULT_DOMAIN =COI.I.COM.UA
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES)

Вот listener.ora
(SID_DESC =
(PROGRAM = hsodbc)
(SID_NAME = ODBCREN)
(ORACLE_HOME = D:\Oracle\ora81)
)

Вот TNSNAMES.ORA
ODBCREN.COI.I.COM.UA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = PENTIUM4)(PORT = 1521))
)
(CONNECT_DATA =
(SID =ODBCREN )
)
(HS = OK)
)

Вот линк
create public database link ODBCREN.COI.I.COM.UA
connect to "SYSDBA" identified by "sysadmin"
using 'ODBCREN';

Вот запрос
select * from paycode@ODBCREN.COI.I.COM.UA

Вот ответ
ORA-02085: database link ODBCREN.COI.I.COM.UA
connects to HO.WORLD

В чем проблема?

ORA-02085: database link name connects to name
Cause: The database link attempted to connect to a database with a different name. The name of the database link must be the same name as the name of the database.

Action: Create a database link with the same name as the database to which it connects
И че?

Когда пишешь такое вот, как советует dba

create public database link ODBCREN
connect to "SYSDBA" identified by "sysadmin"
using 'ODBCREN';

Создается линк ODBCREN.US.ORACLE.COM и понятное дело с запросом ничего не выходит.
