问题描述：源端 10.2.0.4  目标端：11.2.0.4   在目标端划分1T存储与源端做一个NFS

错误：指定dump导出为本地文件系统，正常。   指定dump导出为nfs文件系统，报错。

报错信息如下：

ORA-39001: invalid argument value
ORA-39000: bad dump file specification
ORA-31641: unable to create dump file "/devotd_dpump/expdp_metadata_vspp_sun.dmp"
ORA-27054: NFS file system where the file is created or resides is not mounted with correct options
Additional information: 3
ORA-27037: unable to obtain file status
Linux-x86_64 Error: 2: No such file or directory
Additional information: 3

CAUSE

1. Mount options as per Note 781349.1 - ORA-27054: NFS file system where the file is created or resides is not mounted with correct options
2. Backup using RMAN into this problematic mount point was successful
3. Traditional export using exp to this problematic mount point was successful
4. Creation of a new datafile to this mount point was successful
5. Creation of a file from OS side to this problematic mount point was successful
6. Reboot of the NFS mount point made no difference

SOLUTION

The only solution which worked in this case was to set the below event which disables the mount point parameter checking:
