安装pl/sql develope客户端需修改配置项

1）打开pl/sql develope，工具——首选项——

2）修改监听程序参数文件

初次打开时，内容如下

# listener.ora Network Configuration File: C:\Program_Files\Oracle\DataBase_11G_R2\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 = C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\Program_Files\Oracle\DataBase_11G_R2\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 = C:\Program_Files\Oracle\DataBase_11G_R2

修改为：

# listener.ora Network Configuration File: C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = orcl)
      (ORACLE_HOME = C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1)
     #(PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
)

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

ADR_BASE_LISTENER = C:\Program_Files\Oracle\DataBase_11G_R2

SID_NAME，KEY 的值修改为要访问的oracle实例的名称，HOST 修为 oracle 服务器使用的地址

3）重启listener
