Install Oracle SQL Developer
Oracle SQL Developer is a free integrated development environment that simplifies the development and management of Oracle Database in both traditional and Cloud deployments. Oracle SQL Developer version 17.4 (current version) or later, can connect to Oracle Database Exadata Express Cloud Service using Oracle Wallet, which can be downloaded from the database service. This section describes how to install Oracle SQL Developer.
Note:
The functionality described here requires the Oracle SQL Developer Release version 17.4 (current version) or later running on Java Development Kit (JDK) version 8 update 161 or later.For download and setup instructions to set up Oracle SQL Developer locally for Exadata Express, see Using SQL Developer with Oracle Database Exadata Express Cloud Service on Oracle Technology Network.
Note:
Network connections between Oracle SQL Developer and Exadata Express require Java unlimited strength encryption. Verify that Oracle SQL Developer is running on JDK version 8 update 161 or later, which provides unlimited strength encryption by default. As a convenience specifically for Windows 64-bit users, Oracle SQL Developer provides an option to install the correct JDK version as part of the base software installation.
