I created a link from 817 to 805. The remote global_name has db_domain as WORLD;however, the local one(v. 817) db_domain is null. tnsping works fine but the link failed to do a simple desc on a table. Global_name is set to TRUE on both databases. The remote tnsnames entry is

PSTEST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL= TCP)(Host= estwhp02)(Port= 1521))
(CONNECT_DATA = (SID = PSTEST))
)




On the local, run the followings.

1 create database link PSTEST
2 CONNECT TO SYSADM IDENTIFIED BY PEANUT
3* USING 'PSTEST'
SQL_PSDEV8>/

Database link created.

SQL_PSDEV8>select * from global_name@PSTEST;
select * from global_name@PSTEST
*
ERROR at line 1:
ORA-02085: database link PSTEST connects to PSTEST.WORLD

Any good ideas.
Thx.
