In this section, we will show you how to choose the right version of Oracle SQL Developer 21 for your platform, how to download the file from the official website, and how to verify the checksum and signature of the file to ensure its integrity and authenticity.
Choose the right version for your platform
The first step is to determine which version of Oracle SQL Developer 21 you need for your platform. You can find the list of available downloads on the page. Here are some tips to help you choose the right version:
If you are using Windows, you can choose between two options: Windows 64-bit with JDK 8 included or Windows 32-bit/64-bit. The first option includes both Oracle SQL Developer and an embedded copy of the Java 8 Development Kit (JDK), so you don't need to install Java separately. The second option requires you to install a JDK separately, either JDK 8 or JDK 11. You can download a JDK from . The bit level of the JDK you install will determine if Oracle SQL Developer runs as a 32 or 64 bit application.
If you are using Mac OS X or ARM64, you can choose between two options: Mac OSX with JDK 11 included or Mac ARM64 with JDK 11 included. Both options include both Oracle SQL Developer and an embedded copy of the Java 11 Development Kit (JDK), so you don't need to install Java separately.
If you are using Linux, you can choose between two options: Linux RPM or Other Platforms. The first option is a RPM package that you can install using the rpm command. The second option is a zip file that you can extract and run. Both options require you to install a JDK separately, either JDK 8 or JDK 11. You can download a JDK from .
If you are using another platform that supports Java, you can choose the Other Platforms option. This is a zip file that you can extract and run. You also need to install a JDK separately, either JDK 8 or JDK 11. You can download a JDK from .
Download the file from the official website
The next step is to download the file from the official website. You can do this by clicking on the Download link next to the version of your choice on the page. You will be redirected to a page where you need to accept the license agreement and provide some information about yourself, such as your name, email address, company name, etc. After that, you can click on the Download Now button and save the file to your computer.
The size of the file depends on the version you choose, but it is usually around 400-500 MB. The download time may vary depending on your internet speed and connection quality.
Verify the checksum and signature of the file
The last step before installing Oracle SQL Developer 21 is to verify the checksum and signature of the file. This is an optional but recommended step that ensures that the file you downloaded is not corrupted or tampered with by anyone. To do this, you need to compare the MD5 or SHA1 checksum of the file with the one provided on the page. You also need to check the digital signature of the file using a tool such as GnuPG or OpenSSL.
