expdp使用NFS遭遇ORA-27054

回宁的火车上某用户电话EXPDP使用NFS报错

expdp snms/snms directory=SNMS_BAK_PATH tablespaces=SNMS_SYS_DAT filesize=100M  dumpfile=snms_sys_dat_20110101_%U.dmp logfile=snms_sys_dat_20110101.log

查询 metalink,ORACLE建议采取两种方法

1.设置事件禁用MOUNT检查

Disallow MOUNT POINT checks with event:
"10298 trace name context forever, level 32"

Event 10298 disables the NFS checks in the 10.2 code

 

 

2.用正确参数mount NFS（注意黑色字部分）

RAC including RACone and single instance RAC

In the table below

• Binaries is the shared mount points where the Oracle Home and CRS_HOME is installed.
• Datafiles includes Online Logs, Controlfile and Datafiles
• nfsvers and vers are identical on those OS platforms that has nfsvers.  The ver option is an alternative to the nfsvers option. It is included for compatibility with other operating systems
• Please note that the mount options on each of the following cells are applicable only to those type of files listed in the column heading.
• For RMAN backup sets, image copies, and Data Pump dump files, the "NOAC" mount option should not be specified - that is because RMAN and Data Pump do not check this option and specifying this can adversely affect performance.

* 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required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428)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
*** 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

## The stated mount options for binaries are applicable only if the ORACLE HOME is shared.

Due to Unpublished bug 5856342, it is necessary to use the following init.ora parameter when using NAS with all versions of RAC on Linux (x86 & X86-64 platforms) until 10.2.0.4.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