Question

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:

OracleServiceXE: Started

OracleXETNSListener: Started

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

It says "This page can't be displayed"

I also tested to connect using SqlPlus:

Solution

I have same problem, but I run on oracle linux. After searching and testing, i can connect sqldeveloper to my oracle11g without setting my listener.ora or else

here is the syntax that i run on terminal sql

alter system set LOCAL_LISTENER='(DESCRIPTION_LIST =  (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))))';

then

alter system register;
