If you use SQL Developer 4.2 you do not need an admin user, you can just REST enable your schema and then add REST modules on the REST Dataservices node.
See the Help of SQL Dev 4.2 for details.
I've enabled the schema... But SQL Developer asks for user and password on the panle Rest Development - Rest Data Services...
yeah, don't USE that - do what Peter suggests as shown here
Or you can create a new ORDS dev user following these instructions
Please change your user handle from "991374" to something meaningful. Refer : Video tutorial how to change nickname available
I've installed ORDS with APEX, and I am running it with a command like : java -jar /home/oracle/ords/ords.war standalone --port 8080 --apex-images /oracle/app/product/12.1.0/dbhome/apex/images
I don't remember to have defined a admin user and now I can't connect to ORDS using SQL Developer.
How can I define a admin user to connect and administer the services with SQL Developer.
Here is how you can configure Admin user command line (from ORDS 3.0 documentation): Installing Oracle REST Data Services
As you need a know how about how to administer ORDS with Oracle SQL Developer, following is the documentation (from Oracle SQL Developer 4.2 documentation) link which will help you in detail: SQL Developer: Oracle REST Data Services Support
NOTE: This will help you with not only ORDS administration but as well as developing RESTful Web Services for Oracle Database using ORDS with help of Oracle SQL Developer as IDE for development.
