I installed oracle 10g XE .it is installed and login as HR successfully but when I write query and click on run button. It did not run . I tried to save it but that also did not work. It is not even displaying error or something else. It is running on 8080 port number.
I wrote this code:
SET SERVEROUTPUT ON
dbms_output.put_line('hello');
I also checked services in task manager .This is the status.
Please help.
