How to install Oracle 19c

In this article, we will be discussing how to install Oracle 19c on Windows 10 on your personal laptop. We will be installing Oracle 19.3.

The system requirements to install Oracle 19c are:

• Minimum 2GB of free RAM
• 10GB of free hard-disk space
• A processor based on Intel EM4T or AMD64 architecture
• A display card of minimum resolution of 1024 by 768 pixels

Downloading Oracle 19c

Steps:

1. To download Oracle 19.3 use the link https://www.oracle.com/database/technologies/oracle-database-software-downloads.html
2. In this link, scroll down and download the following version
3. Oracle 19c takes the downloaded folder as the Oracle db_home directory, so if you have downloaded the .zip file in your Windows “Downloads” folder, then move it to a different directory.
4. Create an “app” folder in your C drive.
   1. Copy the Oracle 19c downloaded zip in this folder.
   2. Extract the zip file in this app folder
   3. Rename the extracted folder as db_home.

Installing Oracle 19c

Steps:

1. Sign in to your windows as an Administrator
2. In the extracted folder, that is, db_home, locate the file setup.exe. Right-click on it and select “run as administrator’.
3. Oracle database 19c installer will start. In the next screen of Select Configuration Option, select the first option of Create and configure a single instance database. This option is selected as we are installing on our local machine. Select Next.

4. The next screen will display the option for the type of installation we want to perform. Select the option for Desktop Class. This option is used as we are installing Oracle on your laptop and not on a server grade machine. Select Next.

5. In the next screen, we need to provide Oracle home user. This user will be used to manage the Oracle account on your machine. We will create a new user for this. Select the third option and select Create New Windows User. Specify the user and password. I will be providing User: OCA and password: oracle. You can choose as per your preference.

5. The next screen will contain the important details. The inputs provided here will be used in connecting to the database. Please save this info as you will be requiring it always.

The inputs in this screen are:

• Oracle base: This is the location for all the Oracle products. This will be the location where all the files and directories like Oracle home will be stored. You can provide a different folder by simply typing it in or leave it as the default location of app, this is where we extracted our installation zip.
• Software location. This is the location of your db_home directory. We are not allowed to change this directory. That’s why we moved the downloaded installation file to this location.
• Database file location. This file location will contain all the important files such as Data files, redo log files, control files, server parameter and password files. You can change the location if you want or go with the default location.
• Database edition. It contains all the different editions of Oracle 19c, such as enterprise edition and standard edition. Select the default enterprise edition.
• Character Set. This is the character set of your database. Select the default.
• Next we need to provide Global database name, password and the pluggable database name. These inputs will be needed when we connect to the database. Please save them.
  • Global database name is the name of the database. It will also serve as the SID. We will need this SID while making connections to the database via the client tools like SQL developer. By default it is orcl. You can change it or leave it as default.
  • Password will be the password of the administrative users such as sys or system. If we ever need to logon to the database using an administrative user, use the user name as sys or system and password you provide here. I will provide the password as oracle. Remember this password or save it somewhere.
  • Pluggable database name. Specify a unique pluggable database name. We can change it or leave as default of orclpdb. A warning message will be displayed: “password is not according to Oracle standard” but it will not stop us from the installation.
  • Check the box for Create as Container database. This will create the database as a container. This step will make our database as a container database. A container database supports a maximum of 252 pluggable database.
  • Once again remember to save all of the above details or you will not be able to connect to your database.
  • Click Next. You may get a warning that password is not according to Oracle’s standard, ignore it and click yes to move forward.

This will start the installation of Oracle 19c.

The installer will first check all of the prerequisites. If your laptop doesn’t conform to these, it will display a summary with warnings or errors.

After summary displays everything is ok, click on Install.

Installation may take sometime depending on your hardware.

Last Step

The last thing in this installation is to copy the link of Oracle database 19c enterprise manager. Copy it and bookmark it in your browser.
