连接scan ip出现ORA-12545错误

GRID和数据库版本：11.2.0.1 OS：Solaris 5.10 现象：在客户端连接scan ip时报错 sqlplus system/Oracle@210.10.4.5:1521/pdpt O

GRID和数据库版本：11.2.0.1

OS：Solaris 5.10

现象：在客户端连接scan ip时报错

sqlplus system/Oracle@210.10.4.5:1521/pdpt

ORA-12545: 因目标主机或对象不存在，连接失败

但两台数据库服务器之间连scan ip则没问题

# cat /etc/hosts

192.168.2.1 taian-pt-d1-priv

192.168.2.2 taian-pt-d2-priv

经检查scan ip监听正常，客户端能ping通scan ip

-bash-3.2$ crs_stat -trac资源服务正常
