How To Install Oracle Database 21c Express Edition.
In three steps!
Introduction
In this tutorial, we will learn how to install Oracle Database 21c Express Edition.
Steps
1. Download Oracle Database 21c Express Edition here.
When you try to download it, the system will ask you to log in, if you don’t have an oracle account, you have to create one first. I have written about how to create an oracle account, you can see it here as a guide.
2. Turn off the antivirus.
Before running the installer, you should turn off the antivirus or any other security in your device. This is for your software will not be deleted, because the antivirus will detect it as a virus.
3. Extract the downloaded file, open your download folder, find setup.exe, and run.
Please right-click the setup.exe file and choose run as administrator.
When these windows appear you can click next.
Here you need to tick on ‘I accept the terms in the license agreement’, and click next.
After a while, this window will show. And you have to enter the password. And remember, this password will use to log in to the Oracle database, so you have to remember the password. As you can see from the picture this password will be used for SYS, SYSTEM, and PDBADMIN accounts.
Here, please click install.
And wait while the system is installed.
If this window appears, please click the ‘Allow access’ button.
After the installation is done, click the ‘Finish’ button. You can see from the picture the EM Express URL: https://localhost:5500/em. You can click this link, or type on your browser.
Test to login
You will see a display like this, and please enter the username and enter the oracle database password that you have created before. And click the ‘Login’ button.
After successful login, you will see the Oracle Enterprise Manager like this.
You can try to log in using SQL Plus and type user-name: / as sysdba. And you will see you have connected to Oracle Database 21c Express Edition Release 21.0.0.0.0 — Production
Version 21.3.0.0.0
You also can try to log in using the command prompt and type ‘sqlplus / as sysdba’ without quotes.
There is another way to access the oracle database, which is using SQL developer. We will install this later.
