ocfs certification with 11gr2 rac

We are planning to implement 11gR2 RAC on OCFS2 file system. We are going to have ocr files,voting disk files,database files and flash recovery area files on OCFS2 file system.
Generic Note
ocfs2 is certified for oracle 11gr2 but oracle recommends using asm.
please see this for more information http://download.oracle.com/docs/cd/E11882_01/install.112/e10812/storage.htm#CWLIN262
3.1.3 Supported Storage Options
The following table shows the storage options supported for storing Oracle Clusterware and Oracle RAC files.


For information about OCFS2, refer to the following Web site:
If you plan to install an Oracle RAC home on a shared OCFS2 location, then you must upgrade OCFS2 to at least version 1.4.1, which supports shared writable mmaps.

For OCFS2 certification status, and for other cluster file system support, refer to the Certify page on My Oracle Support.

  1. 刘大,请教一下,ocfs是不是不支持linux6呀。还有如果使用ocfs的话是不是就不用asm了呢?

  2. 最近我正在测试如果云上安装数据库的性能会怎么样,单机可以安装,但是安装rac必须安装ocfs,oracle官方我看也就支持到linux 5 而且我云上的系统还是centos 6.4的。所以就一下几个问题想请教一下您,希望您给予指点。1.如果真想将所有的包括应用数据库放到云上是否可行?这个架构有问题吗?再就是是单机可以还是rac也可以?2.如果真想在上边安装rac的话共享文件只能是ocfs解决的办法吗?而且必须只能安装linux redhat5或者是oracle linux的版本,其他centos等版本不能安装吗?3.如果我要测试云上的数据库用oracle官方出的orion的工具靠谱吗?用哪几个命令测试最接近oracle的性能呢?比如我现在用三个: 1、./orion -run simple -testname test -num_disks 2 2、./orion_linux_x86-64 -run oltp -testname test -num_disks 2 3、./orion_linux_x86-64 -run advanced -testname test1 -num_disks 3 -size_small 8 -size_large 8 -type rand这三个命令可以吗?真心向您请教,希望给予指点。
