#sysctl -p => to take effect of the above command "vi /etc/sysctl.conf"

Reboot the system

Step 7: Copy Oracle Software from shared folder to your OEL server.

Shared Folder is located in /media directory.

Give 777 permission to Oracle Software file and go to directory where you have copied software.
Unzip the same.

Step 8: Login as oracle user and begin software installation.

Go to the location where software exists and start runInstaller.

Uncheck below email notifications for security updates and click Next and YES to continue. 

Here you will get three options:

- Create and configure a database => Using this option, you can install db software and create database.

- Install database software only => Using this option, you can install software only, but will not create database.

I am using 1st option to install and create database. Click NEXT to continue.

Select "Server Class" option and click NEXT to continue.

Select 1st option to install "Single Instance database". The 2nd and 3rd option is for RAC installation

Select "Advanced install" option to get below advanced selections and click NEXT to continue.

Select oracle inventory location and assign oinstall group. Click NEXT to continue.

Select 1st option for general and transactional purpose. The 2nd option is for Data Warehouse.

The default database name is orcl. You can use your own db name. You can also create CDB and PDB databases which is new feature of Oracle DB 12c. If you want to disable this option, uncheck this.

You can enable/disable AMM using below option. Also, you can select characteristics for your database.

If you want to configure sample schemas to be created then you can check below option.

I am not using this option. Click NEXT to continue.

Use below option to select database storage type which are File System or ASM. I am using File System as a default option.

If OEM Cloud Control has already been configured then enter below details for monitoring of this database. I am ignoring this option as i don't have OEM Cloud Control configured.

You can check below option to enable Recovery Area for your database.

You can either create separate passwords for each user or create same password for all users.

Select OSDBA group to grant sysdba privilege. I am using dba group as OSDBA group.

Check any failed prerequisites and correct the same. I am ignoring  below two prechecks and this is testing server.

Swap Size => Increase swap size

Soft Limit maximum stack size => You can set the kernel parameter with correct value.

Check "Ignore All" option and click on YES to continue.

You can verify installation details. Click on "Install" option.

Check below installation steps and rectify the error if you face:

Oracle Database Installation
