错误描述，RAC安装完成后，客户端有一定几率链接失败，报错如下：
ERROR:
ORA-12545: 因目标主机或对象不存在，连接失败
环境中安装RAC Database时候忘记了先配置netca。
故注册下LOCAL_LISTENER
如下：
代码
1
1
,在node1,node2上分别编辑服务器端tnsname.ora (注意,是服务器端的)
2 将下面部分
3 LISTENERS_TEST =
4 (ADDRESS_LIST =
5 (ADDRESS = (PROTOCOL = TCP)(HOST = node1 - vip)(PORT = 1521 ))
6 (ADDRESS = (PROTOCOL = TCP)(HOST = node2 - vip)(PORT = 1521 ))
7 )
8 改为:
9 LISTENERS_TEST =
10 (ADDRESS_LIST =
11 (ADDRESS = (PROTOCOL = TCP)(HOST = 201.150 . 14.19 )(PORT = 1521 ))
12 (ADDRESS = (PROTOCOL = TCP)(HOST = 201.150 . 14.20 )(PORT = 1521 ))
13 )
14 也就是将vip主机名改为ip地址
15
16 2 .在node1上增加以下部分
17 LOCAL_LISTENER =
18 (ADDRESS_LIST =
19 (ADDRESS = (PROTOCOL = TCP)(HOST = 201.150 . 14.9 )(PORT = 1521 ))
20 )
21
22 3 .在node2上增加以下部分
23 LOCAL_LISTENER =
24 (ADDRESS_LIST =
25 (ADDRESS = (PROTOCOL = TCP)(HOST = 201.150 . 14.10 )(PORT = 1521 ))
26 )
27
28 4 ,用system用户登录
29 执行
30 alter system set local_listener = ' LOCAL_LISTENER ' scope = both;
31
32 5 重启所有实例 所有监听.
2 将下面部分

还有一种办法是客户端修改hosts，把vip的命名解析加进去。但是不推荐。
以上主要解决Oracle bug：可以参考metalink 文档ID: 364855.1
