Posted by Sometimes the ORACLE REST DATA SERVICES shows some of the below unexpected and annoying errors which prevents to launch Oracle Apex Instances:
- 404 Not found
- REST data service not available
- The request could not be mapped to any database…..
and so on
I found the below solution and you can try to get rid of from this annoying issue:
- login to SYS with SYSDBA privilege and execute the below command to unlock & Reset password for below users.
|
1 2 3 4 |
alter user APEX_LISTENER identified by apex account unlock; alter user APEX_REST_PUBLIC_USER identified by apex account unlock; alter user APEX_PUBLIC_USER identified by apex account unlock; alter user ORDS_PUBLIC_USER identified by apex account unlock; |
Note: In my case I have used ‘apex’ as password for all the users, you can set your own password.
2. login to Tomcat Web Application Manager
|
1 |
http://localhost:7172/manager |
Note: In my case it is Apache Tomcat.
- If the above URL doesn’t work (assuming your url is correct) then check your Apache tomcat service is running or not.
- After getting into the Web Application Manager through the above URL, Locate the Column ‘Commands’ for Display name = Oracle Application Express Listener
- click the button ‘Stop’ to stop the service
- Now click ‘Start’ to start the service
3. Now launch the application URL and hope you will be able to login to your apex environment.
