Oracle安裝完成后,plsqldev連接報錯；

檢查

listener和tnsnames文件是否修改其監聽IP端口號(服務器內網IP)，檢查完畢后，並無發現問題；

修改

• 修改listener文件

修改前

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\software\oracle\oracle19)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\software\oracle\oracle19\bin\oraclr19.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.4)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

修改后

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\software\oracle\oracle19)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\software\oracle\oracle19\bin\oraclr19.dll")
    )
   (SID_DESC = 
        (GLOBAL_DBNAME = orcl)
        (ORACLE_HOME = C:\software\oracle\oracle19)
        (SID_NAME = orcl)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.4)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )
