Oracle 11g Installation With ASM and Data Guard Setup

In this article we will look at Oracle 11g installation with ASM storage and also setup physical standby on ASM. We will be following below steps for our configuration


We will first setup the primary server and then the standby server


Setup Primary Server


Let us create a virtual machine, install Oracle GRID (which provides us ASM) and then install oracle 11g software. The first step is to Install Oracle Linux 7.7 on Virtualbox.


Oracle Installation Prerequisites


Install below package to perform all oracle installation pre-requisites

yum -y install oracle-rdbms*

Change password for oracle user

passwd oracle

Add grid user and update password

useradd -u 54323 -g oinstall -G dba grid

passwd grid

Create necessary directories

mkdir -p /u01/app/oracle
mkdir -p /u01/app/grid
mkdir -p /u01/app/11.2.0/grid
chown -R grid:oinstall /u01
chownoracle:oinstall /u01/app/oracle
chmod -R 775 /u01
mkdir -p /u02
chown -R oracle:oinstall /u02
chmod -R 775 /u02

Download Oracle 11.2.0.4 gird and database binaries. Copy it to /u02 location

Switch to Oracle user and edit the bash profile

su - oracle
vi .bash_profile

Put below under the bash profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
export ORACLE_SID=proddb

Configure ASM Disks


Our goal is to setup primary database on ASM disks. Let us proceed and configure ASM disks. Install ASM packages

yum -y install oracleasm*
yum -y install kmod-oracleasm

Configure ASM

[root@prod ~]# 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 []: dba
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

Load kernel module

[root@prod ~]# oracleasm init
Creating /dev/oracleasm mount point: /dev/oracleasm
Loading module "oracleasm": oracleasm
Configuring "oracleasm" to use device physical block size
Mounting ASMlib driver filesystem: /dev/oracleasm

Shutdown the virtual machine and Add asm disk to virtual machine of 110 GB size. Go to virtual machine settings > storage > Controller SATA > Add new disk

configure asm disks - add asm disk

Select create new disk

configure asm disks - create new disk

Select VDI and click next

configure asm disks - select vdi

Select Fixed size and click next

configure asm disks - storage on physical hard disk - select fixed size

Give 110 GB size and click on create

configure asm disks - file location and size

It will take some time to create the disk. Once created, start the virtual machine. Check the new added disk is listed via fdisk -l command

configure asm disks - disk fdisk - 1

Create three partitions on /dev/sdb disk to be used as ASM disks

fdisk /dev/sdb

n                        --> create new partition
p
1
<enter>
+50G

n
P
2
<enter>
+50G

n
p
3
<enter>
<enter>

w                        --> save partitions

Create asm disks. Each partition will be used as one disk inside a disk group

oracleasm createdisk DATA1 /dev/sdb1
oracleasm createdisk FRA1 /dev/sdb2
oracleasm createdisk CRS1 /dev/sdb3

Install Grid Software


Switch to grid user, unzip the grid software under /u02

su - grid
cd /u02
unzip p13390677_112040_Linux-x86-64_3of7.zip

Start the runInstaller

cd grid
./runInstaller

Follow the screens to install oracle grid software

Create ASM Diskgroups


As grid user, start asmca utility

asm configuration assistant - disk groups

Click on Create. Give a name to your DATA disk group. This disk group will hold database files. Then click on OK

asm configuration assistant - name to data disk group
asm configuration assistant - configure asm disk group

Similarly create FRA diskgroup

asm configuration assistant - asm instance

Close!
