ASM on vmware workstation  

 

Prerequisites:-

Step 1:

Set up Oracle Database Server on VMware Workstation using( OEL) Linux 7.6 OS Platform?

 

Step 2:

Connect to OEL 7.6 server via putty and install the below packages

 yum -y install -y oracle-database-preinstall-19c

yum -y install oracleasm*

yum -y install kmod-oracleasm*

Add below OS groups

groupadd -g 54327 asmdba
groupadd -g 54328 asmoper
groupadd -g 54329 asmadmin

Add asmdba as secondary group to Oracle user

usermod -a -G asmdba oracle

 

Create Grid User

useradd -u 54331 -g oinstall -G dba,asmdba,asmoper,asmadmin,racdba grid

 

Change the password for Oracle and Grid user

passwd oracle

passwd grid

Create the Directories for Oracle Database installation

mkdir -p /u01/app/oracle
mkdir -p /u01/app/oracle/product/19.3.0/db_home
chown -R oracle:oinstall /u01/app/oracle

Create the Directories for Oracle Grid installation

mkdir -p /u01/app/grid/product/19.3.0/grid_home
chown -R grid:oinstall /u01/app/grid
chmod -R 775 /u01

Configure Oracle ASM

Let us configure Oracle ASM

oracleasm configure -i

 

Load / initiate Oracle ASM

Add 30 GB HDD to virtual machine which we will use to create 3 partitions of 10 GB each for our ASM disks. Open Virtual machine >> Settings >> Storage >> Controller: SATA >> Create new disk

create 3 partitions of 10 GB each for our ASM disks

login as root user to format the  disk

fdisk -l

In the above output the /dev/sdb is not yet formatted. Let’s create 3 partitions on sdb

fdisk /dev/sdb

n                        --> to create new partition
<enter>
<enter>
<enter>
+10G

n
<enter>
<enter>
<enter>
+10G

n
<enter>
<enter>
<enter>
<enter>

w                        --> to save partition table

Create separate ASM Disk for each partition

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

To check asm disks

oracleasm listdisks

ls -lrt /dev/oracleasm/disks

Install Grid Software

Edit Grid user Bash_Profile but take .bash_profile backup before editing it

su - grid

cp .bash_profile .bash_profile.orig

vi .bash_profile

 

Paste below contents

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
ORACLE_SID=+ASM; export ORACLE_SID
ORACLE_BASE=/u01/app/grid; export ORACLE_BASE
ORACLE_HOME=/u02/app/grid/product/19.3.0/grid_home; export ORACLE_HOME
ORACLE_TERM=xterm; export ORACLE_TERM
JAVA_HOME=/usr/bin/java; export JAVA_HOME
TNS_ADMIN=$ORACLE_HOME/network/admin; export TNS_ADMIN

PATH=.:${JAVA_HOME}/bin:${PATH}:$HOME/bin:$ORACLE_HOME/bin
PATH=${PATH}:/usr/bin:/bin:/usr/local/bin
export PATH

umask 022

Save and close vi editor. Execute the bash profile and check the environment variables

. .bash_profile

env|grep ORA

 

Copy the 19c grid software under grid home and unzip it

 

Oracle Database 19c Grid Infrastructure (19.3) for Linux x86-64

https://www.oracle.com/ae/database/technologies/oracle19c-linux-downloads.html

cd $ORACLE_HOME
unzip LINUX.X64_193000_grid_home.zip

unzip LINUX.X64_193000_grid_home.zip

Setup xming and Start the gridSetup.sh as a grid user which will install grid software

cd /u01/app/grid/product/19.3.0/grid_home

Follow below screens to perform the grid software installation

  • Change Disk group name as CRS
  • Select External
  • Click on Change Discovery Path
  • Give Disk Discovery Path as /dev/oracleasm/disks
  • Click on OK

 

Select /dev/oracleasm/disks/CRS1 >> Next

Select Use Same Password for these Accounts >> Specify password >> confirm password >> Next. Click on Yes

Click Next >> Next

Click Next >> Next >> Next

chown -R grid:oinstall /u01
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/
  
chown -R grid:oinstall /u01/app/oraInventory
chmod -R 775 /u01/app/oraInventory

Click on fix and check again

Install the missing package

[root@prim rpm]# pwd
/u01/app/grid/product/19.3.0/grid_home/cv/rpm
[root@prim rpm]# rpm -ivh cvuqdisk-1.0.10-1.rpm

To install package (under root user):

cd /u01/app/grid/product/19.3.0/grid_home/cv/rpm

rpm -ivh cvuqdisk-1.0.10-1.rpm

Configure ASM Diskgroups

The grid installer allows you to only create one diskgroup (CRS). We need to start the asmca utility in order to create DATA and FRA diskgroup which are required for database installation. Click on Create

 

  • Give Disk Group Name as DATA
  • Select External(None)
  • Select /dev/oracleasm/disks/DATA1
  • Click on OK

Click on Create

  • Give Disk Group Name as FRA
  • Select External(None)
  • Select /dev/oracleasm/disks/FRA1
  • Click on OK

 

 

Install Oracle Software
