ORA-12505, TNS:listener does not currently know of SID given in connect

I'm using JDeveloper when I try to create a database connection with the hr/hr user I get this message:

Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
The Connection descriptor used by the client was:
localhost:1521:ORCL

then I go to the command line and I put tnsping ORCL

C:\Users\Administrator>tnsping ORCL

Solution

Your listener service doesn't clearly state that it has any ORCL database SID here, on this host. When you used TNSPING command to check connectivity, you walked around this by using Oracle EZCONNECT adapter that resolves all needed connect info itself, but JDBC driver needs either clear declaration of SID in listener or clear command to use EZCONNECT adapter.

So are two ways to solve this:

Open listener.ora and find these lines:

(SID_LIST =
 (SID_DESC =
  (SID_NAME = CLRExtProc)
  (ORACLE_HOME = C:\app\oracle\virtual\product\12.2.0\dbhome_1)
  (PROGRAM = extproc)
  (ENVS = "EXTPROC_DLLS=ONLY:C:\app\oracle\virtual\product\12.2.0\dbhome_1\bin\oraclr11.dll")
 )
)

Replace them with these:

(SID_LIST =
 (SID_DESC =
  (SID_NAME = CLRExtProc)
  (ORACLE_HOME = C:\app\oracle\virtual\product\12.2.0\dbhome_1)
  (PROGRAM = extproc)
  (ENVS = "EXTPROC_DLLS=ONLY:C:\app\oracle\virtual\product\12.2.0\dbhome_1\bin\oraclr11.dll")
 )
 (SID_DESC =
  (SID_NAME = ORCL)
  (ORACLE_HOME = C:\app\oracle\virtual\product\12.2.0\dbhome_1)
  (GLOBAL_DBNAME = ORCL)
 )  
)

Then use "lsnrctl stop" and "lsnrctl start" to restart the listener. This change will register new SID_DESC block with description of your database SID in listener.

Change JDBC string to connect through EZCONNECT adapter and not through SID. Please, post your JDBC connection string if you want exact answers, but in overall you shouldn't use:
```
jdbc:oracle:thin:@213.130.77.281:1521:orcl
```
And use instead:
```
jdbc:oracle:thin:@//213.130.77.281:1521/orcl
```
This change will tell JDBC to use EZCONNECT adapter.
