使用NFS安装oracle软件，nfsoracle软件
昨天，使用openfiler创建nas存储系统，并安装oracle软件，前面一切顺利，到创建数据库时报ora错误，原来使用nfs安装oracle数据库时，mount选项有特殊要求，整理总结如下，以备查：
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

* 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required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428)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Due to Unpublished bug 5856342, it is necessary to use the following init.ora parameter when using NASwith all versions of RAC on Linux (x86 & X86-64 platforms) until 10.2.0.4.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.

按照上面所示，设置参数，结果仍然报错ora-27086,错误信息如下：
[oraten@yue ~]$ oerr ora 27086 27086, 00000, "unable to lock file - already in use" // *Cause: the file is locked by another process, indicating that it is // currently in use by a database instance. // *Action: determine which database instance legitimately owns this file.
虽然oracle支持nfs，但使用nfs的情景比较少，多数使用nfs来备份数据库或者存放归档
NFS做表空间的存储, 网络异常一下, oracle就挂了, 快加硬盘才是正道.
1.Oracle Linux 6.4(64位)
2.启动光盘，最小花的系统，启动后允许你选择安装源（通过nfs，ftp等方式安装），可以用来系统维护、拯救系统
3.uek(Unbreakable Enterprise Kernel)的内核的启动光盘， uek内核是Oracle Linux、Oracle Database、中间件和硬件工程师团队合作的结果，是一个快速、现代、可靠的内核，专门针对Oracle软件和硬件进行了优化
