1.1 配置ASM 磁盘

1.1.1 Asm配置

twonodes#/etc/rc.d/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 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

Start Oracle ASM library driver on boot (y/n) [n]: y

Scan for Oracle ASM disks on boot (y/n) [y]: y

Writing Oracle ASM library driver configuration: done

Initializing the Oracle ASMLib driver: [ OK ]

Scanning the system for Oracle ASMLib disks: [ OK ]

不可以执行对/dev/dm-*进行化分区,因为两个nodedm-*的连接的设备不一定相同.

chown grid:asmadmin /dev/dm*

oracleasm createdisk OCRVG /dev/dm-7

这样的操作是不建议的.

使用fdisk进行分区,这里就分一个区

#fdisk /dev/mapper/Ds8100_ocr_1

nàpà1…àw

#partprobe 同步磁盘信息

#fdisk –l的输出为:

Disk /dev/mapper/ds8100_1: 128.8 GB, 128849018880 bytes

。。。。。。

Device Boot Start End Blocks Id System

/dev/mapper/ds8100_ocr_1p1 1 15665 125829081 83 Linux

。。。。。。

检查DEV目录下有没有磁盘分区设备

#ls –lt /dev/mapper

……

brw-rw---- 1 root disk 253, 20 Aug 13 09:37 ds8100_ocr_1p1

创建oracleasm磁盘

#oracleasm create disk OCRVG /dev/mapper/Ds8100_ocr_1p1

#oracleasm listdisks

OCRVG

节点2

#partprobe

#ls –lt /dev/mapper 检查存在分区的设备

brw-rw---- 1 root disk 253, 20 Aug 13 09:37 ds8100_ocr_1p1

#oracleasm scandisks

#oracleasm listdisks

OCRVG

使用了asmlib管理磁盘就不需要设置磁盘访问的权限

如果不使用asmlib(redhat6),则需要手工配置udev

1.1 加载hangcheck模块

echo "options hangcheck-timer hangcheck_tick=30 hangcheck_margin=180" >> /etc/modprobe.conf

echo "/sbin/modprobe hangcheck-timer" >> /etc/rc.local

1.2 配置/etc/hosts文件

[root@rac1 ~]# more /etc/hosts

10.90.12.231 dnlgl1

10.90.12.232 dnlgl1-vip

172.10.10.1 dnlgl1-priv

10.90.12.233 dnlgl2

10.90.12.234 dnlgl2-vip

172.10.10.2 dnlgl2-priv

10.90.12.235 scan_vip

[root@rac1 ~]# hostname

Dnlgl1

[root@rac2 ~]# hostname

dnlgl2

1.3 配置/etc/resolv.conf

twonodes# more /etc/resolv.conf

nameserver 10.150.207.50
