安装完Oracle 11g rac后，在10g的客户端的 tnsnames.ora中配置好，scanip,但是无法访问，报错为目标主机不存在，折腾了很久，没弄明白，后面查到，系统初始化参数里有local_listener这一项，在这里可以对host的值加以修改，将scanip注册进来、在监听器中使用v

在racnode1服务器上：
[root@racdb1 ~]# su - Oracle
[Oracle@racdb1 ~]$ sqlplus /nolog

local_listener string (DESCRIPTION=(ADDRESS_LIST=(AD
DRESS=(PROTOCOL=TCP)(HOST=rac1_vip)(PORT=1521))))
SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=racscan)(PORT=1521))))' scope=both sid='racdb1';

rac1:
SQL> show parameter local_listener
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string (DESCRIPTION=(ADDRESS_LIST=(AD
DRESS=(PROTOCOL=TCP)(HOST=rac1
-vip)(PORT=1521))))
SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.2.111)(PORT=1521))))' scope=both sid='orcl1';
SQL> alter system register;
rac2:
SQL> show parameter local_listener
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string (DESCRIPTION=(ADDRESS_LIST=(AD
DRESS=(PROTOCOL=TCP)(HOST=rac2
-vip)(PORT=1521))))
SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.2.112)(PORT=1521))))' scope=both sid='orcl2';
SQL> alter system register;
随后使用windows客户端连接成功：
C:\Users\WJW>sqlplus system/qweasd@192.168.2.200:1521/orcl
