在linux系统下,将另一台aix机器上的存储mount到linux下通过nfs,然后在linux下使用expdp导出数据存储在mount到linux下的磁盘上报错
ORA-27054: NFS file system where the file is created or resides is not mounted with correct options

解决访问
Alter system set events '10298 trace name context forever,level 32'
执行这个命令，不需要重新启动,但在下次数据库重新启动后就失效了，需要再次手工执行。
如果想数据库重新启动后，自动执行这个命令，则执行下面的命令：
SQL>alter system set event='10298 trace name context forever,level 32' scope=spfile;

今天在虚拟机环境下做实验，在将RAC环境修改为flashback on时，报出了ORA-27054错误，错误代码如下：
Errors in file /u01/app/oracle/admin/racdb/udump/racdb2_ora_25551.trc:
ORA-38701: Flashback database log 2 seq 1 thread 2: "/u01/flashback/RACDB/flashback/o1_mf_%u_.flb"
ORA-27054: NFS file system where the file is created or resides is not mounted with correct options
从错误描述可以看出，闪回目录是通过nfs文件系统来实现的，而系统挂载nfs时，采用了错误的参数选项，导致oracle报错。上网查资料，通过文档359515.1顺利解决问题。整理部分内容如下：

* 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required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428)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Due to Unpublished bug 5856342, it is necessary to use the following init.ora parameter when using NAS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.
