测试的简单过程如下(略去了一些基本步骤).
首先测试两个数据库的连通性:
$ sqlplus "/ as sysdba"
SQL*Plus: Release 9.2.0.4.0 - Production on Tue Oct 31 10:36:31 2006
Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.
Connected to:
Oracle9i Enterprise Edition Release 9.2.0.4.0 - 64bit Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.4.0 - Production
SQL> show parameter glob
NAME TYPE VALUE
------------------------------------ ----------- ---------------------
global_context_pool_size string
global_names boolean TRUE
SQL> select * from global_name;
GLOBAL_NAME
----------------------------------------------------------------------
HSBILL.HURRAY.COM.CN
SQL> exit
Disconnected from Oracle9i Enterprise Edition Release 9.2.0.4.0 - 64bit Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.4.0 - Production
bash-2.03$ tnsping mars
TNS Ping Utility for Solaris: Version 9.2.0.4.0 - Production on 31-OCT-2006 10:39:41
Copyright (c) 1997 Oracle Corporation. All rights reserved.
Used parameter files:
/opt/oracle/product/9.2.0/network/admin/sqlnet.ora
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.31.110)(PORT = 1521))) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = mars)))
OK (10 msec)
两个数据库分别创建db link:
9i的数据库:
bash-2.03$ sqlplus repadmin/repadmin
SQL*Plus: Release 9.2.0.4.0 - Production on Tue Oct 31 10:57:49 2006

JServer Release 9.2.0.4.0 - Production
SQL> create public database link "MARS.HURRAY.COM.CN" connect to repadmin identified by repadmin using 'MARS';
Database link created.
SQL> select * from dual@mars;

10g的数据库:
bash-2.03$ sqlplus "/ as sysdba"

SQL> select username from dba_users where username='REPADMIN';
USERNAME
------------------------------
REPADMIN
SQL> connect repadmin/repadmin
Connected.
SQL> select * from tab;
no rows selected
SQL> select * from global_name;
GLOBAL_NAME
--------------------------------------------------------------------------------
MARS.HURRAY.COM.CN
SQL> create public database link "HSBILL.HURRAY.COM.CN" connect to repadmin identified by repadmin using 'HSBILL';
Database link created.
SQL> select * from dual@hsbill;

两个数据库分别创建测试表：
SQL> connect eygle/eygle
Connected.
SQL> create table eygle as select * from v$session;
