将12c连接到sql developer

Question

我的程序： 1. checking container， 2. altering container n unlocking

我在tnsnames.ora

中添加了以下内容

PDBORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = pdborcl)
    )
  )

我已解锁hr帐户，并在建立连接时提及pdborcl作为服务名称。

my listener.ora

  # listener.ora Network Configuration File:       C:\Users\SURBHI\Documents\product\12.1.0\dbhome_1\network\admin\listener.ora
  # Generated by Oracle configuration tools.

 SID_LIST_LISTENER =
  (SID_LIST =
   (SID_DESC =
     (SID_NAME = CLRExtProc)
    (ORACLE_HOME = C:\Users\SURBHI\Documents\product\12.1.0\dbhome_1)
    (PROGRAM = extproc)
    (ENVS =      "EXTPROC_DLLS=ONLY:C:\Users\SURBHI\Documents\product\12.1.0\dbhome_1\bin\oraclr1     2.dll")
      )
  )

LISTENER =
  (DESCRIPTION_LIST =
         (DESCRIPTION =
     (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
       (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

我尝试过几个例子，比如在命令提示符下使用tnsping pdborcl，这样可以得到OK结果。

但到目前为止我还没有得到积极的结果。
