监听器配置没有问题，为了方便本人讲两个节点的listener.ora文件内容修改为一模一样的配置。
[grid@RAC01 admin]$
LSNRCTL> status

(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=10.134.30.47)(PORT=1521)))
The listener supports no services
The command completed successfully
此时看到监听器no services，其实所有的问题都是与这个no services有关的，后续的内容中我会重点关注解决这个问题。
经过初步的检测个人感觉问题不可能出在服务器监听这一块。故此怀疑可能出在与监听相关的初始化参数上。
7. 检查数据库两个与监听相关的参数：
SQL> show parameter local_lis
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string (DESCRIPTION=(ADDRESS_LIST=(AD
DRESS=(PROTOCOL=TCP)(HOST=RAC0
2-vip)(PORT=1521))))
SQL> show parameter remote_lis
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
remote_listener string RACSCAN.localdomain.:1521
SQL> show parameter local_lis
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string (DESCRIPTION=(ADDRESS_LIST=(AD
DRESS=(PROTOCOL=TCP)(HOST=RAC0
