Mount Options for Oracle files when used with NFS on NAS devices (文档 ID 359515.1)

In this Document

Purpose

Scope

Details

RAC including RACone and single instance RAC

Single Instance (non-RAC)

References

APPLIES TO:

Oracle Database - Enterprise Edition - Version 10.1.0.2 to 12.1.0.1 [Release 10.1 to 12.1]

Information in this document applies to any platform.

Oracle Clusterware, Oracle Real Application Clusters, NAS

PURPOSE

The options with which the NAS systems should be mounted are described. This note does not cover the new dNFS feature that was introduced in 11g.

SCOPE

This document is relevant to all environments using Oracle Clusterware & RAC.

DETAILS

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required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428) 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

Due to Unpublished bug 5856342, it is necessary to use the following init.ora parameter when using NAS with all versions of RAC on Linux (x86 & X86-64 platforms) until 10.2.0.4.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