(1) installation and configuration

I. Confirm the Linux kernel version

[Root @ sigleNode ~] # Uname-r

Ii. Install the asmlib package

[Root @ sigleNodeasm] # rpm-ivh *. rpm

3. Add two hard disks and partition them without formatting.

[Root @ sigleNodedev] # fdisk/dev/hda

Command (m for help): n

Command action

E extended

P primary partition (1-4)

P

Partition number (1-4): 1

First cylinder (1-261, default 1): 1

Last cylinder or + size or + sizeM or + sizeK (1-261, default 261): 261

Command (m for help): w

The partition table has been altered!

Calling ioctl () to re-read partition table.

Syncing disks.

Run the same command to partition/dev/hdb.

The partition result is as follows:

[Root @ sigleNode ~] # Fdisk-l

Disk/dev/hda: 2147 MB, 2147483648 bytes

16 heads, 63 sectors/track, 4161 cylinders

Units = cylinders of 1008*512 = 516096 bytes

Device Boot Start End Blocks Id System

/Dev/hda1 1 4161 2097112 + 83 Linux

Disk/dev/hdb: 2147 MB, 2147483648 bytes

16 heads, 63 sectors/track, 4161 cylinders

/Dev/hdb1 1 4161 2097112 + 83 Linux

Iv. Configure the ASM Environment

[Root @ sigleNode ~] #/Etc/init. d/oracleasm configure

Processing 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

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

Default user to own the driver interface []: oracle

Default group to own the driver interface []: dba

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

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

Writing Oracle ASM library driver configuration: done

Initializing the Oracle ASMLib driver: [OK]

Scanning the system for Oracle ASMLib disks: [OK]
