安裝oracleASM

問題：oracleasm status不能啟動

解決方案：

[root@localhost ~]# oracleasm status
Checking if ASM is loaded: no
Checking if /dev/oracleasm is mounted: no
[root@localhost ~]# oracleasm exit
[root@localhost ~]# oracleasm init
Creating /dev/oracleasm mount point: /dev/oracleasm
Loading module "oracleasm": oracleasm
Mounting ASMlib driver filesystem: /dev/oracleasm
[root@localhost ~]# oracleasm status
Checking if ASM is loaded: yes
Checking if /dev/oracleasm is mounted: yes

一。手工搞定安裝

 

1. 檢查是否已安裝及系統內核

  --查看內核

  [root@xclrac1 /]# uname -rm

  2.6.39-400.17.1.el6uek.x86_64 x86_6

 

  --查看asm包

  [root@xclrac1 /]# rpm -qa|grep asm

  libatasmart-0.17-4.el6_2.x86_64

  [root@xclrac1 /]#

 

  [root@xclrac1 db2]# cat /proc/version

  Linux version 2.6.39-400.17.1.el6uek.x86_64 ([e-mail]) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Fri Feb 22 18:16:18 PST 2013

 

   [root@xclrac1 ~]# cat /etc/issue

  Oracle Linux Server release 6.4

  Kernel \r on an \m

 

2. 去官網找到相應系統對應的asm下載安裝.

 以前Oracle Linux 5 如下:

  --安裝ASM, support->asm-> lib放最后 

   rpm -Uvh oracleasm-support-2.1.7-1.el5.x86_64.rpm

   rpm -Uvh oracleasm-2.6.18-194.el5-2.0.5-1.el5.x86_64.rpm

   rpm -Uvh oracleasmlib-2.0.4-1.el5.x86_64.rpm

  現在Oracle 6.4就不需這么麻煩:

   2.1 去系統光盤找到asmlib support的安裝包(rpm -Uvh oracleasm-support-2.1.8-1.el6.x86_64.rpm)裝上

   2.2 去Oracle官網，下載Oracle Linux 6 對應的asmlib.rpm包並裝上

   2.3 重新查看

 [root@xclrac1 db2]# rpm -qa|grep asm

 oracleasmlib-2.0.4-1.el6.x86_64

 libatasmart-0.17-4.el6_2.x86_64

 

 3. 安裝成功后，通過 oracleasm命令檢查並管理asmlib

 [root@xclrac1 /]# oracleasm status

 Checking if ASM is loaded: yes

 Checking if /dev/oracleasm is mounted: yes

 

 [root@xclrac1 ~]# oracleasm update-driver

 

 

二。yum快速搞定安裝

 http://www.oracle.com/technetwork/server-storage/linux/uln-095759.html

 

Getting Oracle ASMLib via the Unbreakable Linux Network

Installing ASMLib via ULN

  Now that the system is registered with ULN, it can install the software. Log in as root and run:

                                           

 # yum install oracleasm-support oracleasmlib oracleasm-`uname -r`

 

On Oracle Linux 5 and older, run the following command instead:

 

# up2date -i oracleasm-support oracleasmlib oracleasm-`uname -r`

 

This will install the support tools, the library, and the kernel driver for the currently running kernel.

 

Note: If you are running the Unbreakable kernel, the ASMLib kernel driver is included in that kernel package, and the oracleasm-`uname -r` package should not be specified.

 

安裝成功后。就可以.配置和管理asm 磁盤了。

 

1. 我在這創建5個磁盤

  cd C:\Program Files\Oracle\VirtualBox

VBoxManage.exe createhd -filename D:\OracleVM\ASM\asm1.vdi -size 5120 -format VDI -variant Fixed

VBoxManage.exe createhd -filename D:\OracleVM\ASM\asm2.vdi -size 5120 -format VDI -variant Fixed

VBoxManage.exe createhd -filename D:\OracleVM\ASM\asm3.vdi -size 5120 -format VDI -variant Fixed

VBoxManage.exe createhd -filename D:\OracleVM\ASM\asm4.vdi -size 5120 -format VDI -variant Fixed

VBoxManage.exe createhd -filename D:\OracleVM\ASM\asm5.vdi -size 5120 -format VDI -variant Fixed

 

2. 在Oracle VM中附加進去。 這個VM也可以用命令，但不太好使。

  Settings -> Storage->Controller:SATA ->Add Hard Disk

3. 更改成共享模式

VBoxManage.exe modifyhd D:\OracleVM\ASM\asm1.vdi --type shareable

VBoxManage.exe modifyhd D:\OracleVM\ASM\asm2.vdi --type shareable

VBoxManage.exe modifyhd D:\OracleVM\ASM\asm3.vdi --type shareable

VBoxManage.exe modifyhd D:\OracleVM\ASM\asm4.vdi --type shareable

VBoxManage.exe modifyhd D:\OracleVM\ASM\asm5.vdi --type shareable

 

4. 檢查下狀態 

    a. VBoxManage list vms

    b. 進入linux系統

  [root@rac1 dev]# ls sd*

   sda sda1 sda2 sdb sdc sdd sde sdf

   //其中   sdb sdc sdd sde sdf 就是掛上的那5個盤

 

5. 來fdisk 磁盤。

    依次:  fdisk sdb   fdisk sdc   fdisk sdd    fdisk sde    fdisk sdf 

   附了個例子:  

[root@rac1 dev]# fdisk sdb

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Building a new DOS disklabel with disk identifier 0x1f132726.

Changes will remain in memory only, until you decide to write them.

After that, of course, the previous content won't be recoverable.

 

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

 

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to

         switch off the mode (command 'c') and change display units to

         sectors (command 'u').

[root@rac1 dev]# ls sd*

最后的結果:

 

[root@rac1 dev]# ls sd*

sda sda1 sda2 sdb sdb1 sdc sdc1 sdd sdd1 sde sde1 sdf sdf1

 

 

6. 依次創建asm磁盤 

[root@xclrac1 ~]# oracleasm createdisk DISK1 /dev/sdb1

Writing disk header: done

Instantiating disk: done

[root@xclrac1 ~]# oracleasm createdisk DISK2 /dev/sdc1

Writing disk header: done

Instantiating disk: done

[root@xclrac1 ~]# oracleasm createdisk DISK3 /dev/sdd1

Writing disk header: done

Instantiating disk: done

[root@xclrac1 ~]# oracleasm createdisk DISK4 /dev/sde1

Writing disk header: done

Instantiating disk: done

[root@xclrac1 ~]# oracleasm createdisk DISK5 /dev/sdf1

Writing disk header: done

Instantiating disk: done

 

7. 檢查下效果 

[root@xclrac1 ~]# oracleasm listdisks

DISK1

DISK2

DISK3

DISK4

DISK5

 

8. 讓oracleasm把磁盤給找出來

[root@xclrac1 ~]# oracleasm scandisks

Reloading disk partitions: done

Cleaning any stale ASM disks...

Scanning system for ASM disks...

 

9.配置asm 磁盤的管理用戶

[root@xclrac1 Packages]# oracleasm configure -i

Configuring the Oracle ASM library driver.

 

Default user to own the driver interface []: oracle

Default group to own the driver interface []: dba

 

[root@xclrac1 Packages]# oracleasm configure

ORACLEASM_ENABLED=true

ORACLEASM_UID=oracle

ORACLEASM_GID=dba

ORACLEASM_SCANBOOT=true

ORACLEASM_SCANORDER=""

ORACLEASM_SCANEXCLUDE=""

ORACLEASM_USE_LOGICAL_BLOCK_SIZE="false"

 

    至此，這個Linux的asm就掛載成功了。 剩下的工作就是把這個OS再Clone一下。然后你就會發現。這些磁盤都能被兩個OS找到並使用了。

就可以放心裝RAC了。

   C:\Program Files\Oracle\VirtualBox>VBoxManage.exe clonehd D:\OracleVM\OLE_RAC1\O
