Troubleshoot RESTful Web Services

If you receive “Your service is currently unavailable” error message or “500 Internal Server Error” HTTP status code when accessing RESTful web services deployed in Exadata Express, it could be caused by a problem with the corresponding handler.

For example, a PLSQL syntax error in the handler (such as a missing semicolon) or an SQL runtime exception (such as ORA-01403: no data found) are common reasons for this message. To confirm this, examine the Error-Reason header in the HTTP response using developer tools within your browser or in your REST client.


Use Base64 decoder to decode the value of the Error-Reason header.
