10.2.0.2 以后是可以这样用的, 当然ASM 要到10.2.0.4 以后才支持 块设备 block device ,之前 只支持 裸设备 raw devices
[root@vrh1 ~]# ls -l /dev/mapper/VolGroup00-LogVol01
brw-rw---- 1 root disk 253, 1 Feb 20 21:48 /dev/mapper/VolGroup00-LogVol01
==> block device
odm finding:- Linux 2.6 Kernel Deprecation of Raw Devices [ID 357492.1]From Oracle RDBMS version 10.2.0.2.0 and higher, block devices can be accessed via any of the following methods and utilized by the RDBMS:
- Direct block device access
- ASMLib mapped devices
- OCFS2 devices
- LVM2 mapped devices (single instance only)
- Note: The Oracle Universal Installer (OUI) for Oracle10g Real Application Clusters (RAC) (10.1.0 or 10.2.0) does not support direct block device access for Clusterware devices. The OUI for Oracle11g Real Application Clusters (RAC) 11.1.0.6.0 and higher supports direct block device access for Clusterware devices.
复制代码 Direct block device access=> 从10.2.0.2 开始oracle支持 直接使用 block device 块设备, 也包括LV 形式的block device=>LVM2 mapped devices (single instance only) , 但LVM 仍不支持RAC |
