Linux Oracle10gR2 creates an ASM instance to install the database

This example is created based on ASMLib or a bare device.

1. Install the support packages required by asm
A. Download the support package from the Oracle Website: here
B. Download the corresponding asm installation package based on the Linux kernel:

Oracleasm-2.6.18-8.el5-2.0.4-1.el5.i686.rpm
Oracleasm-2.6.18-8.el5PAE-2.0.4-1.el5.i686.rpm
Oracleasm-2.6.18-8.el5xen-2.0.4-1.el5.i686.rpm
Oracleasmlib-2.0.3-1.el5.i386.rpm
Oracleasm-support-2.0.4-1.el5.i386.rpm
C. Install rpm-Uvh ...... -- nodeps

 

1.1 Install ASMLib

# Cd/orahome/wangnc/asmlib

# Rpm-Uvh oracleasm-support-2.1.3-1.el4.i386.rpm oracleasm-2.6.9-55.ELsmp-2.0.3-1.i686.rpm oracleasmlib-2.0.4-1.el4.i386.rpm

 

1.2 Configure ASMLib

#/Etc/init. d/oracleasm configure

...

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) [n]: y

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

...

# Df-ha | grep oracleasm

Oracleasmfs 0 0 0-/dev/oracleasm

 

The following describes how to enable or disable the Automatic startup of oracleasm:

#/Etc/init. d/oracleasmDisable

#/Etc/init. d/oracleasmEnable

 

1.3 Physical disk partition

ForASM hardDiskYesPartition(Only one partition,Hard Disks are used hereSDb):

# Fdisk-l | grep Disk

Disk/dev/sda: 250.0 GB, 250059350016 bytes

Disk/dev/sdb: 250.0 GB, 250059350016 bytes

 

#Fdisk/dev/SDB

Command (m for help ):N

P

Partition number (1-4 ):1

First cylinder (1-30401, default 1 ): <Enter>

Last cylinder or + size or + sizeM or + sizeK (1-30401, default 30401 ): <Enter>

Command (m for help ): W

 

# Fdisk-l/dev/sdb

Disk/dev/sdb: 250.0 GB, 250059350016 bytes

255 heads, 63 sectors/track, 30401 cylinders

Units = cylinders of 16065*512 = 8225280 bytes

Device Boot Start End Blocks Id System

/Dev/sdb1 1 30401 244196001 83 Linux

 

1.4 Create an ASM Disk

These disks are empty disks that do not contain any content. during creation, the physical disk must contain a partition number, such as sdb1.

 

The ASM disk name can be uppercase letters, numbers, and underscores (_) and start with a letter:

#/Etc/init. d/oracleasm createdisk VOL1/dev/sdb1

Marking disk "VOL1" as an ASM disk: [OK]

 

If Failed is prompted, you can track the log:

# Tail-f/var/log/oracleasm

Attached disk deletion statement:

#/Etc/init. d/oracleasm deletedisk VOL1

 

Check Configuration:

#/Etc/init. d/oracleasm querydisk VOL1

#/Etc/init. d/oracleasm querydisk/dev/sdb1

#/Etc/init. d/oracleasm listdisks

# Ls-l/dev/oracleasm/disks /*

#/Etc/init. d/oracleasm status

 

1.5 Create initialization parameter file

Note that asm_diskstring must start with 'orcl.

# Su-oracle

$ Export ORACLE_SID = + ASM

$ Vi $ ORACLE_HOME/dbs/init$ ORACLE_SID. Ora

Asm_diskstring = 'orcl: VOL *'

Background_dump_dest = '/u01/app/oracle/admin/+ ASM/bdump'

Core_dump_dest = '/u01/app/oracle/admin/+ ASM/cdump'

User_dump_dest = '/u01/app/oracle/admin/+ ASM/udump'

Instance_type = 'asm'

Large_pool_size = 12 M

Remote_login_passwordfile = 'shared'
