Oracle使用NFS的mount选项

原创 Linux操作系统 作者:zecaro 时间:2011-03-23 11:37:08 0 删除 编辑

        使用nfs放oracle的数据文件,按下文中的参数配置后,出现错误

Linux-x86_64 Error: 37: No locks available。

        加上nolock参数即可(具体原因待查)。此外如果用remount加载nfs的话,存放归档时报错(数据文件没试过)。umount后再mount最好了。下面附nfs的参数配置。

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。

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required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428)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Due to Unpublished bug 5856342, it is necessary to use the following init.ora parameter when using NAS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