Building Oracle11gRAC in linux (IV)

Oracle11g RAC construction in linux (iv) III. Configure shared storage configuration ASM management preparation

1) OCRDISK: stores CRS resource configuration information

2) VOTEDISK: The arbitration disk, which records the node status.

3) DataDisk: stores datafile, controlfile, redologfile, and spfile.

4) RecoveryArea: stores flashbackdatabase log, archivelog, and rmanbackup.

Install the asm package

Install On node1 and node2 respectively

Node1:

[Root @ node1 ~] #Cd/soft

[Root @ node1 soft] #Ls

Asm linux_11gR2_database_1of2.zip linux_11gr2_databasesilicate f2.zip linux_11gR2_grid.zip

Oracleasm-2.6.18-194.el5-2.0.5-1.el5.i686.rpm

Oracleasmlib-2.0.4-1.el5.i386.rpm

Oracleasm-support-2.1.3-1.el5.i386.rpm

Make sure that it matches with the kernel version.

Note:

1. Check whether the asm software package version 2.6.18-194. el5 and the system kernel version 2.6.18-194. el5 match the two and you can continue the installation;

2. i386 represents 32 bits.

[Root @ node1 asm] #Uname-a or uname-r

// Check whether the system kernel version is the same as the asm version.

Linux node1 2.6.18-194. el5 #1 SMP Tue Mar 16 21:52:43 EDT 2010 i686 i686i386 GNU/Linux

 

Install software package under node1

[Root @ node1 asm] #Rpm-ivh *

// Install three software packages, I-install, v-installation process, h-display installation information, *-all software packages

 

[Root @ node1 asm] #Rpm-qa | grep asm// View the information about the installation.
 

 

Install software package under node2

Under node2:

[Root @ node1/] #Scp/soft/asm/* node2:/home/oracle/

// Copy the software package under asm from node1 to node2.

Or[Root @ node1 soft] #Scp-r asm node2:/home/oracle/

1) create a partition on the shared Array

In the node1 partition, view it in node2

OCR + VOTE: 3 1 GB Disks

DATABASE Disk: 2 5 GB

RECOVERY Disk: 2 4 GB

The three 1 GB disks are OCR_VOTE1 disks, and two of them are images.

One of the two 5g ASM_DATA1 disks is an image.

One of the two 4G ASM_RCY1 disks is an image.

2) create an asm disk and configure an asm disk (node1 and node2)

On node1

[Root @ node1 soft] #Serviceoracleasm configure

Processing the Oracle ASM library driver.

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

Driver. Thefollowing 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

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 []:Asmadmin

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

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