啟監聽時，報TNS-12560、TNS-00530錯誤

配置好listener.ora與tnsnames.ora後，執行啟動監聽命令後，報如下錯誤：

[Oracle@gc1 admin]$ lsnrctl start

仔細檢查這二設定檔，無語法錯誤。且tns檔案都是使用主機名稱進行串連，懷疑可能/etc/hosts中ip配置有問題。

--查看/etc/hosts內容

[oracle@gc1 admin]$ vi /etc/hosts

 

# Do not remove the following line, or various programs

# that require network functionality will fail.

# Do not remove the following line, or various programs

--查看當前系統ip

[root@gc1 ~]# ifconfig

這二ip不同，於是root使用者修改/etc/hosts中ip地址資訊，如下：

[oracle@gc1 oradata]$ su - root

Password:

[root@gc1 ~]# vi /etc/hosts

 

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 node1 localhost.localdomain localhost

::1 localhost6.localdomain6 localhost6

# 192.168.188.116

10.1.55.129 gc1

192.168.8.115 gc2

修改儲存後，再啟動監聽，成功

[oracle@gc1 ~]$ lsnrctl start
