基于CentOS与VmwareStation10搭建Oracle11G RAC 64集群环境:3.安装Oracle RAC-3.1.安装并配置ASM驱动

3.1.安装并配置ASM驱动

3.3.1.检查内核

[root@linuxrac2 etc]# uname -r

2.6.18-164.el5

  下载以下rpm(注意rpm包版本和Linux内核版本一致):

  Oracle ASMlib下载地址:http://www.oracle.com/technetwork/server-storage/linux/downloads/rhel5-084877.html

3.1.3. 初始化 asmlib(在所有节点执行)

启动oracle asmlib:

[root@linuxrac1 etc]# /etc/init.d/oracleasm start

Initializing the Oracle ASMLib driver: [  OK  ]

Scanning the system for Oracle ASMLib disks: [  OK  ]

启用asmlib:

[root@linuxrac1 etc]# /etc/init.d/oracleasm enable

以root用户配置节点linuxrac1

[root@linuxrac1 /]# /etc/init.d/oracleasm configure -i

Configuring the Oracle ASM library driver.

 

This will configure the on-boot properties of the Oracle ASM library

driver.  The following questions will determine whether the driver is

loaded on boot and what permissions it will have.  The current values

will be shown in brackets (‘[]‘).  Hitting <ENTER> without typing an

answer will keep that current value.  Ctrl-C will abort.

 

Default user to own the driver interface []: grid

Default group to own the driver interface []: oinstall

3.1.4. 磁盘分区(节点1执行)

1.查询磁盘

[root@linuxrac1 dev]# fdisk -l

 

Disk /dev/sda: 32.2 GB, 32212254720 bytes

255 heads, 63 sectors/track, 3916 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x0005464c

 

Device Boot      Start         End      Blocks   Id  System

/dev/sda1   *           1          39      307200   83  Linux

Partition 1 does not end on cylinder boundary.

/dev/sda2              39         545     4063232   82  Linux swap / Solaris

Partition 2 does not end on cylinder boundary.

/dev/sda3             545        3917    27085824   83  Linux

 

Disk /dev/sdb: 4294 MB, 4294967296 bytes

255 heads, 63 sectors/track, 522 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk /dev/sdc: 21.5 GB, 21474836480 bytes

255 heads, 63 sectors/track, 2610 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00000000

2.磁盘分区,注意分区的Last cylinder的值不能选错,选择default 值就好。

[root@linuxrac1 /]# fdisk /dev/sdb

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

Building a new DOS disklabel with disk identifier 0x52362e93.

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‘).

 

Command (m for help): n

Command action

   e   extended

   p   primary partition (1-4)

p

Partition number (1-4): 1

First cylinder (1-522, default 1): 1

Last cylinder, +cylinders or +size{K,M,G} (1-522, default 522): 522

 

Command (m for help): w

The partition table has been altered!

 

Calling ioctl() to re-read partition table.

Syncing disks.

  /dev/sdc,/dev/sdd,/dev/sde执行相同操作。

3.1.5.创建 asm 磁盘,在节点1执行

1.使用oracleasm createdisk 创建ASM磁盘label:在一个节点执行即可

[root@linuxrac1 /]# /etc/init.d/oracleasm createdisk OCR_VOTE /dev/sdb1

Marking disk "OCR_VOTE" as an ASM disk: [  OK  ]

[root@linuxrac1 /]# oracleasm createdisk OCR_VOTE /dev/sdb1

Device "/dev/sdb1" is already labeled for ASM disk "OCR_VOTE"

[root@linuxrac1 /]# oracleasm createdisk DATA /dev/sdc1

Writing disk header: done

Instantiating disk: done

[root@linuxrac1 /]# oracleasm createdisk DATA2 /dev/sdd1

Writing disk header: done

Instantiating disk: done

[root@linuxrac1 /]# oracleasm createdisk FRA /dev/sde1

Writing disk header: done

Instantiating disk: done

[root@linuxrac1 /]# oracleasm scandisks

Reloading disk partitions: done

Cleaning any stale ASM disks...

Scanning system for ASM disks...

2.查看创建后的ASM磁盘

[root@linuxrac1 /]# oracleasm listdisks

DATA

DATA2

FRA

OCR_VOTE

3.检查磁盘是否已挂载在oracleasm文件系统:

[root@linuxrac1 /]# ls -l /dev/oracleasm/disks

total 0

brw-rw---- 1 grid oinstall 8, 33 Sep 24 18:29 DATA

brw-rw---- 1 grid oinstall 8, 49 Sep 24 18:29 DATA2

brw-rw---- 1 grid oinstall 8, 65 Sep 24 18:29 FRA

brw-rw---- 1 grid oinstall 8, 17 Sep 24 18:29 OCR_VOTE

 

3.1.6. 节点2扫描识别ASM磁盘

节点2扫描识别ASM磁盘

root@linuxrac2 etc]# oracleasm scandisks

Reloading disk partitions: done

Cleaning any stale ASM disks...

Scanning system for ASM disks...

Instantiating disk "OCR_VOTE"

Instantiating disk "DATA"

Instantiating disk "DATA2"

Instantiating disk "FRA"
