最近几天在虚拟机上新搭建了个rac，本地（远程）登陆数据库第一个节点连不上，第二节点可以。情况如下：
节点1：

直接在虚拟机上登陆没有问题，如下：
[oracle@rac1 bin]$ sqlplus /nolog
SQL*Plus: Release 10.2.0.1.0 - Production on Mon Jun 18 11:11:43 2012

自己电脑上建2节点的监听：
RAC2 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.3.218.155)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = RACDB)
)
)
RAC1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.3.218.154)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = RACDB)
)
)
在我本机登陆：
C:\Users\hp>sqlplus /nolog
SQL*Plus: Release 10.2.0.1.0 - Production on 星期一 6月 18 15:09:42 2012
