1) Configure VM
Create New VM during which you will have to select below list of parameters
⦁ VM Name
⦁ VM Machine files location
⦁ OS Type
⦁ Version
⦁ Ram allocation from physical Ram available on host machine (here Windows 10)
⦁ Select “Create a virtual hard disk now” as we are building a new machine.
⦁ Finally click on create it will open a new window where it will ask some details for
⦁ disk size
⦁ disk type
⦁ disk allocation type.

⦁ Processor increase the number of cpus if you have resources
Here we have to add more storage when required for Grid Home, Oracle Home, Asm Disks….etc
For now we have left it with only 1 disk for root.
So here we will add some more storage now only.
By clicking on create below window will open where we have to update the disk name and size we want.
Then click on create button
Same way we have added 3 more disks for asm data, fra & ocr &vd.
Network >>
We have to have 2 adapter
Adapter 1>> Bridged Adapter for Internet in vm
Adapter 1>> Promiscuous Mode >> Allow All
Adapter 2>> Host-Only Adapter
Shared Folders>>
add a folder from windows host so that we can keep the files over there and copy it to our unix machine easily without any scp or winscp tools
Finally our Machine is ready with all the requirements now add the iso file which we have downloaded from oracle edelivery site.
Now we have to hit start button to start the virtual server for Linux installation.
Select the language of your wish.
At this screen it will take some time to identify installation source, software selection and finally it gives this screen.
Select “server with GUI” on left part and from right part select all the add-ons. (for selection of add-ons you can use mouse or space bar on key board.)
Now we have to format the disks we have added for installation. So click on “INSTALLATION DESTINATION”
After selecting the disk we need to select “I will configure partitioning” from “Other storage Options”
Now select “Standard Partition” and use the “+” sign to add the mount points
You need to user “TAB” key on keyboard to move between options and
now select Mount Point as / (root) and give the space you want for root
generally it wont take more than 10GB but we are installing many packages and other oracle packages so I kept it as 20 GB.
Once mount point is added make sure that
Device Type = Standard Partition
Filesystem = ext3
In the same was as said above add home, boot, tmp, var with same device type as standard and file system as ext3
Try to keep Swap atleast the size of the physical memory allocated to server.
Swap will have file system as swap only, you cant change it.
Make sure all the mount points have same ext3 as file system type and standard partition as device type and hit DONE at top left corner
After we hit Done, It will prompt to Accept Changes – do it using tab key as it won accept mouse clicks here.
Then we can start “Begin Installation”
Add root password as per your wish.
If we are using a less complex root password it will prompt us to change it but we can use it by clicking Done 2 times.
Add any user but not oracle or grid. You can uncheck the “require a pass”
Now the installation will continue for some time say 30 mins or so.
We have selected 1973 packages it will complete all of them and then will prompt for reboot.
One Installation is done hit reboot
After Reboot we have to do some settings as per below screenshots.
Accept the Licence Information.
You can get those details of IP from your pc by going to
Control Pannel>>Network & Internet>>View network status and tasks>>change adaptor setting (on right side of the window)>> right click on your active wifi or ethernet and click on status and then details.
Change the hostname as per your wish
Select Ethernet (enp0s3) and click configure
Once it is open go to IPv4 settings and change the Method = Manual
Click on Add and start giving the ip address for the bridged adapter, and hit save
Add dns as 8.8.8.8
Hit Done to exit this window
Hit Finish Configuration server will reboot
Hit on “Not Listed” and login as root
Select the language of your wish
Click Next after selecting key board layout.
Click on next it does not make difference you enable location or not.
You can skip this
Click on the blue button, “Start Using Oracle Linux Server”
Now we have to start partitioning of the disks we have added and install many packages which will make the system ready for oracle installation.
Update the hosts file:
[root@oel76-19 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.56.4 oel76-19 oel76-19.lostworld.com --- (add this line to hosts file)
[root@oel76-19 ~]#
Oracle Installation Prerequisites
Perform either the Automatic Setup or the Manual Setup to complete the basic prerequisites. The Additional Setup is required for all installations.
Automatic Setup
If you plan to use the "oracle-database-preinstall-19c" package to perform all your prerequisite setup, issue the following command.
By running this setup all the requirements would be fulfilled automatically from the package like oracle user, groups etc.
# yum install -y oracle-database-preinstall-19c (this will create our base oracle requirements)
It is probably worth doing a full update as well, but this is not strictly speaking necessary.
# yum update -y (this will update everything on linux)
[root@oel76-19 ~]# yum install kmod-oracleasm – (this will install oracleasm kernel files.)
[root@oel76-19 ~]# yum install oracleasm-support – (this will install oracleasm related rpms)
It's worth running the all the YUM commands listed in the manual setup section.
Depending on the OS package groups you have selected, some additional packages might also be needed.
If you are using RHEL7 or CentOS7, you can pick up the PRM from the OL7 repository and install it. It will pull the dependencies from your normal repositories.
# yum install -y https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
Manual Setup
If you have not used the "oracle-database-preinstall-19c" package to perform all prerequisites, you will need to manually perform the following setup tasks.
Add the following lines to the "/etc/sysctl.conf" file.
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
kernel.panic_on_oops = 1
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.conf.all.rp_filter = 2
net.ipv4.conf.default.rp_filter = 2
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500
Run one of the following commands to change the current kernel parameters, depending on which file you edited.
/sbin/sysctl -p (# Or) /sbin/sysctl -p /etc/sysctl.d/98-oracle.conf
Add the following lines to a file called "/etc/security/limits.d/oracle-database-preinstall-19c.conf" file.
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft nproc 16384
oracle hard nproc 16384
oracle soft stack 10240
oracle hard stack 32768
oracle hard memlock 134217728
oracle soft memlock 134217728
Someone in the comments suggested you might need to add the previous lines into the "/etc/security/limits.conf" file also for CentOS7. This is definitely not needed for OL7, but worth considering if the installer gives prerequisite failures for these settings.
The following packages are listed as required. Many of the packages should be installed already.
yum install -y bc
yum install -y binutils
yum install -y compat-libcap1
yum install -y compat-libstdc++-33

useradd -u 54321 -g oinstall -G dba,oper oracle
Uncomment the extra groups you require.
Additional Setup
The following steps must be performed, whether you did the manual or automatic setup.
Set the password for the "oracle" user.
passwd oracle
Set secure Linux to permissive by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.
SELINUX=permissive
Once the change is complete, restart the server or run the following command.
# setenforce Permissive
If you have the Linux firewall enabled, you will need to disable or configure it, as shown here. To disable it, do the following.
# systemctl stop firewalld
# systemctl disable firewalld
If you are not using Oracle Linux and UEK, you will need to manually disable transparent huge pages.
After disabling firewall & selinux, we will format and create the mount points using our extra disks which we have added for oracle home & Asm disks. Follow the below steps to complete them
Format the new disks for u01 mount point.

Assigning a Label with e2label, once you have created and formatted a partition, you should assign it a label using the e2label command.
This allows you to add the partition to /etc/fstab using a label instead of using a device path, thereby making the system more robust.
To add a label to a partition, type the following command as root:
/sbin/e2label /dev/sdb1 /u01
Then add the new partition to /etc/fstab by editing the file, this way it will be mounted at reboot:
[root@oel76-19 /]# cat /etc/fstab|grep -i u01
/dev/sdb1 /u01 ext3 defaults 1 2
To check the label use this command:
/sbin/tune2fs -l /dev/sdb1 |grep volume
Mount the new file system:
First create the base directory and assign it to the user that will own it
[root@vmractest3 root]# mkdir /u01
[root@vmractest3 root]#chown -R oracle:oinstall /u01
Then mount it
[root@vmractest3 root]# mount /dev/sdb1 /u01

Putting mount points directly under root without mounting separate disks to them is typically a bad idea. It's done here for simplicity, but for a real installation "/" storage should be reserved for the OS.
Unless you are working from the console, or using SSH tunnelling, login as root and issue the following command.
xhost +hostname
The scripts are created using the cat command, with all the "$" characters escaped. If you want to manually create these files, rather than using the cat command, remember to remove the "\" characters before the "$" characters.
cd ~oracle
vi .bash_profile
Update the below settings in bash profile of oracle user

[oracle@oel76-19 dbhome_1]$ unzip 19c_V982063-01.zip
Set DISPLAY to start the grid installation.
export DISPLAY=local computer ip:0.0
[oracle@oel76-19 ~]$ echo $DISPLAY
192.168.1.9:0.0
[oracle@oel76-19 ~]$ xclock (you will see a clock picture on your screen)
FROM here actual oracle software installation is started.
Go to the grid home which we have already created and unzipped the grid software over there.
cd /u01/app/19.0.0/grid
[oracle@oel76-19 grid]$ ./gridSetup.sh (type it and hit enter below screen will open)
[root@oel76-19 ~]#
[root@oel76-19 ~]# cd /u01/app/oracle/product/19.0.0/dbhome_1/
[root@oel76-19 dbhome_1]#
[root@oel76-19 dbhome_1]# ./runInstaller
From other putty session I have set display and started asmca utility to create the remaining diskgroups.
[oracle@oel76-19 ~]$
[oracle@oel76-19 ~]$ export DISPLAY=192.168.1.9:0.0
[oracle@oel76-19 ~]$ asmca
Once we have created the remaining diskgroups we can continue with our installation.
