oracle 11g rac 客户端如何配置
请教如何配置rac客户端如何配置，我的客户端连接单库是没问题的；第一次安装rac，不知道客户端改如何配置。
客户端配置：hosts文件
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
#eth0 Public
10.9.10.231racnode1.ctz.comracnode1
10.9.10.232racnode2.ctz.comracnode2
#eth1 Private
192.168.10.231racnode1-priv.ctz.comracnode1-priv

#SCAN
10.9.10.235 scan-yu.com
10.9.10.236 scan-yu.com
tnsnames.ora文件
不知道怎么配置

修改了两个节点的local_listener参数
SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=10.9.10.233)(PORT=1521))))' scope=both sid='ora11g1';
SQL> show parameter local_listener;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string (DESCRIPTION=(ADDRESS_LIST=(AD
DRESS=(PROTOCOL=TCP)(HOST=10.9

SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=10.9.10.234)(PORT=1521))))' scope=both sid='ora11g2';

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string (DESCRIPTION=(ADDRESS_LIST=(AD

客户端tnsnames.ora文件配置内容
ORA11G =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.9.10.233)(PORT = 1521))

现在从客户端连接rac报连接超时
