安裝pl/sql develope客戶端需修改配置項
2）修改監聽程式引數檔案初次開啟時，內容如下
# 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
修改為：
# 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 的值修改為要訪問的oracle例項的名稱，HOST 修為 oracle 伺服器使用的地址
3）重啟listener
