Oracle 使用nfs挂载的目录不能进行归档

在做实验时将Oracle的归档目录放在nfs服务器上，启动数据库就会死掉，也不能进行归档。
 
在报警日志中发现

重新修改挂载方式
 
mount 192.168.1.31:/arc /mnt  -o rsize=65534,wsize=65534,hard,noac,actimeo=0 /mnt
 
在修改后重新启动数据库发现还是起不了

这个再加一个nolock选项就可以了
 
mount 192.168.1.31:/arc /mnt  -o rsize=65534,wsize=65534,hard,noac,actimeo=0,nolock /mnt
