oracle9i与sqlserver2005在同个机器,并且机器名为ce1d379e086e4ea
OS:SERVER2003
sqlserver2005 数据库实例名zb 用户 sa 密码sa oracle9i 数据库实例名zb
1 在%oracle_home%\tg4msql\admin\下新添加initsqlserver2005.ora
内容如下
HS_FDS_CONNECT_INFO="SERVER=ce1d379e086e4ea/IP;DATABASE=zb"
HS_FDS_TRACE_LEVEL=OFF
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
修改%oracle_home%\network\admin\下listener.ora
在SID_LIST_LISTENER下添加如下内容
(SID_DESC =
(GLOBAL_DBNAME = tg4msql)
(PROGRAM = tg4msql)
(SID_NAME = sqlserver2005)
(ORACLE_HOME = D:\oracle\ora92)
)

--
SID_DESC =
      (SID_NAME = kss)
      (ORACLE_HOME = E:\oracle\product\10.2.0\db_1)
      (PROGRAM = tg4msql)
    )
)
2 重新启动listener
lsnrctl stop start
成功
修改%oracle_home%\network\admin\下tnsnames.ora
3 添加如下内容
sql =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = ce1d379e086e4ea)(PORT = 1521))
)
(CONNECT_DATA =
(SID = sqlserver2005)SID=SID_NAME=KSS
(HS=OK)
)
)

4 数据源的配置。

用sys登陆sqlplus给我dbcxbj数据库的dbcxbj用户赋予create public database link权限
用dbcxbj登陆sqlplus创建public database link
create public database link orasql connect to sa identified by sa using 'sql';
创建成功
查看sqlserver2005里zb数据库student表内容
