1. 安装启动 PL/SQL 错误

eg:

ORA-12514 TNS 监听程序当前无法识别连接描述符中请求服务的解决方法

解决方法：

修改文件

D:\app\Feihong247\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora

如下：

源文件：

# listener.ora Network Configuration File: D:\app\Feihong247\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =

    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:\app\Feihong247\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\Feihong247\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )

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

ADR_BASE_LISTENER = D:\app\Feihong247

修改为：

# listener.ora Network Configuration File: D:\app\Feihong247\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
	
      (SID_DESC =
      (GLOBAL_DBNAME = ORCL)
      (ORACLE_HOME = D:\app\Feihong247\product\11.2.0\dbhome_1)
      (SID_NAME = ORCL)
      )

    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:\app\Feihong247\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\Feihong247\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )

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

ADR_BASE_LISTENER = D:\app\Feihong247

然后重新启动oracle的监听服务即可重新使用PL/SQL。
