oracle link binaries,Oracle环境中使用NFS的mount选项

在oracle环境中使用NFS，在mount的时候需要修改一些选项，否则可能导致各种问题，比如ORA-27086和ORA-27054错

误。不管你是将Oracle安装在NFS设备也好，是将datafile放置在NFS设备也好，是备份到NFS设备也好，如果出现相关的错误，则需要检查

下是否mount的选项有问题。一般只要用hard方式来mount的，都不会有太多问题。

* 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10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug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Due to Unpublished bug 5856342, it is necessary to use the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.
