oracle - 将 12c 连接到 sql developer 时得到 ora 12514

Question

我的程序：1.检查容器，2.更改容器n解锁

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)
    )
  )

我已经解锁了 hr 帐户，并pdborcl在建立连接时提到了服务名称。

我的听众.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))
    )
  )

我已经尝试了几件事，比如在命令提示符下使用 tnsping pdborcl，它给出了 OK 的结果。

但直到现在我还没有得到积极的结果。
