How to solve error Check for integrity of file "/etc/resolv.conf" failed when run ./runcluvfy.sh?
问题
我想在Oracle Linux操作系统上安装Oracle数据库12cR1实时应用程序集群。我已经在节点1和节点2上完成了所有配置，但在安装网格基础设施时出现了以下错误：
检查“/etc/resolv.conf”中所有服务器的DNS响应
从“/etc/resolv.conf”中指定的每个名称服务器检查名称“kaash-his-2”的响应
节点名称 来源 注释 状态
从“/etc/resolv.conf”中指定的每个名称服务器检查名称“kaash-his-1”的响应
节点名称 来源 注释 状态
文件“/etc/resolv.conf”的完整性检查失败
这是文件resolv.conf的输出：
[root@KAASH-HIS-1 tmp]# cat /etc/resolv.conf
由NetworkManager生成
nameserver 10.93.200.222
nameserver 10.93.200.223
[root@KAASH-HIS-2 ~]# cat /etc/resolv.conf
由NetworkManager生成
nameserver 10.93.200.222
nameserver 10.93.200.223
另一个错误：
开始检查/dev/shm是否作为临时文件系统挂载...
错误：
PRVE-0426：作为/dev/shm挂载的内存中文件系统的大小为“33554432k”兆字节，小于节点“”所需的“2048”兆字节
PRVE-0426：作为/dev/shm挂载的内存中文件系统的大小为“33554432k”兆字节，小于节点“”所需的“2048”兆字节
检查/dev/shm是否作为临时文件系统挂载失败
我已经在/etc/fstab文件中添加了/dev/shm，并且以下是文件的详细信息：
[root@KAASH-HIS-1 tmp]# cat /etc/fstab
/etc/fstab

请问如何解决这些错误？

I want to install oracle database 12cR1 Real application cluster on oracle linux operating system .
I did all configurations in node 1 and node 2 but during the installation of grid infrastructure I got following errors :
checking DNS response from all servers in "/etc/resolv.conf"
checking response for name "kaash-his-2" from each of the name servers specified in "/etc/resolv.conf"
Node Name Source Comment Status
------------------------ ------------------------ ----------
checking response for name "kaash-his-1" from each of the name servers specified in "/etc/resolv.conf"
Node Name Source Comment Status
------------------ ------------------------ ----------
Check for integrity of file "/etc/resolv.conf" failed
and this is the output of file resolv.conf
[root@KAASH-HIS-1 tmp]# cat /etc/resolv.conf

nameserver 10.93.200.222
nameserver 10.93.200.223
the other error :
Starting check for /dev/shm mounted as temporary file system ...
ERROR:

and I added already the file /dev/shm in file /etc/fstab and this is the file details :

How to solve these errors please ?

编辑文件/etc/resolv.conf并为所有节点添加搜索和域：
[root@KAASH-HIS-1 tmp]# vi /etc/resolv.conf
# 由NetworkManager生成
搜索 "本地域名"
域 "本地域名"
域名服务器 10.93.200.222
域名服务器 10.93.200.223
关于/dev/shm大小错误，您可以使用以下命令作为root用户更改大小并挂载：
# mount -o remount,size=2G /dev/shm
然后通过以下命令确认大小：
# df -h
在安装过程中，如果挂载的/dev/shm大小大于2048M，可以忽略警告。
英文:
After days of search I found the solution for these errors :
1- Edit file /etc/resolv.conf and add search and domain for all nodes :
[root@KAASH-HIS-1 tmp]# vi /etc/resolv.conf
# Generated by NetworkManager
search "local-domain-name"
domain "local-domain-name"
nameserver 10.93.200.222
nameserver 10.93.200.223
2- about the /dev/shm size error
you can change the size and mount using the following command as root user :
# mount -o remount,size=2G /dev/shm
then confirm the size by using
# df -h
and during the installation you can ignore the warning if the mounted size for /dev/shm greater than 2048M
