Oracle12c PRVF-0002 : 无法检索本地节点名

解决办法：

修改/etc/hosts文件 加上主机名

[root@single grid]# cat /etc/hosts
# 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

[root@single grid]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       single localhost.localdomain localhost
::1     single localhost6.localdomain6       localhost6
