前提回現

修改了主機名稱，由hyldb修改為hyl。

問題現象

配置監聽，警告提示，如下所示：

解決方案

1、檢查1521連接埠

[root@hyl ~]# netstat -a

--查看連接埠佔用情況，查明1521連接埠並未被佔用

2、檢查hosts

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

修改前：

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1       hyldb localhost.localdomain localhost

::1             localhost6.localdomain6 localhost6

192.168.56.101  hyl

~

~

~

--由於修改了主機名稱（hyldb修改為hyl），將之前配置中hyldb內容刪除

修改為：

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1       localhost.localdomain localhost

::1             localhost6.localdomain6 localhost6

192.168.56.101  hyl

~

~

~

~

 

3、檢查network

# vi /etc/sysconfig/network

--確認添加了如下資訊

NETWORKING=yes

HOSTNAME=hyl

 

4、檢查ipv6是否關閉

 

查看ipv6狀態，查看其是否被關閉

[root@hyl ~]# lsmod |grep ipv6

ipv6                  435105  17 cnic

xfrm_nalgo             43333  1 ipv6

 

補充：關閉ipv6方法1） # vim /etc/modprobe.conf在其中加入下面這一行，install ipv6 /bin/true儲存並退出。2）# vim /etc/sysconfig/network在其中加入下面配置項：NETWORKING_IPV6=noIPV6INIT=no

 

重啟後查詢：

[root@hyl ~]# lsmod |grep ipv6

--沒有顯示ipv6相關資訊，表示ipv6已經關閉

 

5、重啟系統後，查看hostname

[root@hyl ~]# hostname

--查詢主機名稱

hyl

 

6、再次執行netca

配置監聽、dbca建庫成功。
