ODBC - источник под названием ODBCREN в system DSN
проверял, нормально соединяется с БД Interbase.
---------------------------
создаем Датабасе линк
create public database link SQL2.WORLD
connect to SYSDBA identified by "sysad"
using 'ODBCREN';
------------------------------------
Делаем запрос -
select * from STDTRFS@SQL2.WORLD
-----------------------------------------------------------------
Получаем сообщение
ORA-02086:following severe error from SQL2.WORLD
ORA-28511:lost RPC connection to heterogeneos remote agent using
SID=(DESCRIPTION=(ADRESS_LIST=(ADRESS=(PROTOCOL=TCP)(HOST=Pentium4)(PORT=1251)))(CONNECT_DATA=(SERVICE_NAME=ODBCREN)))

помогите или скажите, что с Interbase невозможно сделать Database link.
