ORA-27054故障排除

在数据备份过程中，由于目标是使用NFS文件系统，因此在导入的时候遇到了BUG，报错如下
ORA-39001: invalid argument value
ORA-39000: bad dump file specification
ORA-31641: unable to create dump file "/exp/bak/expdp_01.dmp"
ORA-27054: NFS file system where the file is created or resides is not mounted with correct options
Additional information: 6
通过查询metalink id :387700.1
文档上说可能的问题有以下几种：
a) The mount table (eg; /etc/mnttab) can be read to check the mount options
b) The NFS mount is mounted with the "hard" option
c) The mount options include rsize>=32768 and wsize>=32768
d) For RAC environments, where NFS disks are supported, the "noac" mount option is used.
文档上指出通过设置event 10298事件可以避免，不过设置event 10298需要重启数据库生效，目前为生产环境，这方法不能用。
通过调整上述的参数，hard，rsize，wsize都不能解决。
最后检查NFS的配置，发现客户端的/etc/filesystems中未加入mount nfs文件系统的条目
增加以下条目后，重新mount，解决。
#vi /etc/filesystems
/exp:
        dev             = /exp
        vfs             = nfs
        nodename        = 192.168.1.20
        mount           = true
        options         = rw,bg,hard,intr,proto=tcp,vers=3,rsize=65536,wsize=65536,timeo=600
        account         = false
#umount /oraexp
#mount /oraexp
建议大家以后遇到类似问题，先检查/etc/filesystems文件，这个问题都是由于大家都喜欢使用以下方式mount nfs导致。
mount -o rw,bg,hard,intr,proto=tcp,vers=3,rsize=65536,wsize=65536,timeo=600 192.168.1.20:/exp /exp
//相关metalink 文档如下：
ORA-19504 ORA-27054 Errors mounting NFS file system [ID 370513.1]
RMAN Backup Fails With RMAN-03009 ORA-19504 ORA-27054 NFS file system where the file is created or resides is not mounted with correct options [ID 1472448.1]
ORA-27054: NFS file system where the file is created or resides is not mounted with correct options [ID 781349.1]
//另外设置10298的过程如下：
1) set the Event 10298 in the init file
event="10298 trace name context forever, level 32"
if you are using the spfile then the following can be done
SQL> alter system set event='10298 trace name context forever, level 32'scope= spfile ;
Once you set the above parameter restart the instance check as follows
SQL> select name, value from v$parameter where name = 'event';
NAME VALUE
---------- ------------------------------------------------------------
Event 10298 trace name context forever, level 32
1 row selected.

* NFS mount option “forcedirectio” is required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428)
** AIX is only supported with NAS on AIX 5.3 TL04 and higher with Oracle 10.2.0.1 and later (NetApp)
*** NAS devices are only supported with HPUX 11.23 or higher ONLY 

# These mount options are for Linux kernels 2.6 and above for older kernels please check Note 279393.1

Due to Unpublished bug 5856342, it is necessary to use the following init.ora parameter when using NAS
with all versions of RAC on Linux (x86 & X86-64 platforms) until 10.2.0.4. This bug is fixed and included in 10.2.0.4 patchset.

结果还是不行，继续查，惨烈，是个bug，ID 9115046.8

Bug 9115046  ORA-27054 from EXPDP to NFS disk which does not have "noac" set

Affects:

Product (Component)	Oracle Server (Rdbms)
Range of versions believed to be affected	Versions BELOW 12.1
Versions confirmed as being affected	11.1.0.7 11.1.0.6 10.2.0.4
Platforms affected	Generic (all / most platforms affected)

 

Fixed:

 

This issue is fixed in

12.1 (Future Release) 11.2.0.2 (Server Patch Set)

Description

ORA-027054 error is reported by expdp when run against a  RAC enabled database if the target location for the data pump  data file is an NFS disk which does not have the "noac" property set against it. "noac" is required for datafiles and many other database file types but should not be needed for expdp output files.   

Workaround   Use a different destination for the datapump export file   which does have relevant attribut
