oracle 创建dblink后无法使用

prettyboy123123 2011-12-21 04:11:36

创建语句:
create database link mcc59_to_167 connect to "LINGTU" identified by "lingtu" using 'lingtu';

tnsnames.ora文件配置如下:

167 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.17.12.167)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = lingtu)
)
)

172.17.12.59 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.17.12.59)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)

创建dblink提示创建成功，但是查询时提示
SQL> select count(*) from mcc_track@mcc59_to_167;
select count(*) from mcc_track@mcc59_to_167
*
ERROR at line 1:
ORA-12154: TNS:could not resolve the connect identifier specified

global_names设置为false了已经
alter system set global_names=false;

高手们帮忙看下什么问题啊?谢谢

改成167还是不行啊

create public database link mcc59168
　　 connect to lingtu identified by "lingtu"
　　 using '167';

create public database link mcc59167
　　 connect to lingtu identified by "lingtu"
　　 using '(DESCRIPTION =
　　 (ADDRESS_LIST=
　　 (ADDRESS=(PROTOCOL=TCP)(HOST=172.17.12.167)(PORT=1521))
　　 )
　　 (CONNECT_DATA=
　　 (SERVICE_NAME=lingtu)
　　 )
　　 )';

这两种方式我都试了，还是不行啊。

应该是这样吧：

create database link mcc59_to_167 connect to "LINGTU" identified by "lingtu" using '(DESCRIPTION =

  (ADDRESS_LIST =

  (ADDRESS = (PROTOCOL = TCP)(HOST = 172.17.12.167)(PORT = 1521))

  )

  (CONNECT_DATA =

  (SERVICE_NAME = lingtu)

  )

  )
