Please kindly help me as I just installed Oracle 11g but cannot connnect using SQL Devloper using the settings below:
Username: system
Password: mypassword
Hostname: localhost
Port: 1521
SID: XE
Error message:
Status : Failure -Test failed: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
I checked on Windows Services:

I also unable to connect to admin page: **http://localhost:8080/apex/f?p=4950**
