Connecting with SQL Developer
Oracle SQL Developer can connect to Oracle Database Exadata Express Cloud Service. Security is enforced by using an Oracle Wallet, which can be downloaded from the database service. Steps to do this and run SQL Developer are shown below.
Connections require the Java Unlimited Strength Cryptography feature. This is provided automatically via Java Development Kit (JDK) version 8 update 161 or higher.
The Windows 64-bit distribution of SQL Developer includes an embedded JDK and requires no additional steps.
