I am very new to Apex and I am completing prerequisite tasks so I can complete the, "Building an Application Using Oracle Application Express: Part 1” and I ran into a problem. While going through the, "Re-engineering Your Database Using Oracle SQL Developer Data Modeler 3.1", tutorial I became stuck on step 6. Instead of my screen reading, "The status is Success. Click Connect" it reads, "Status: Failure - Test failed: IO Error: The Network Adapter could not establish the connection." Up to step 5 I have done everything as instructed in the tutorial, which I have placed a link to below on the bottom."Network Adapter" does not refer to the network hardware in your PC, but to a component of Oracle SQL Developer. This is a generic message meaning that SQL Developer has failed to connect to the database using the connection details provided.
I am confused about what my next course of action should be. I checked my Network Adapter and it seems to be working fine and it is not giving me any other trouble. I don't think the adapter has any physical problems either.
I am new to Apex and not sure what to do.At that stage you're not anywhere near APEX yet.
Does anyone out there have an idea of a direction I could take to solve the problem or an idea of why that particular error message came up?Double check the connection details and try it again.
