Oracle 更改服務名方法

1.運行db的sqlplus：sqlplus sys/sys as sysdba （sys/sys爲“用戶名”/“密碼”）

   或配置client的監聽後運行Client的sqlplus

2. （可省略）查看當前服務名：SQL> show parameter service_name

3. 修改服務名：SQL> alter system set service_names='orcl' scope=both;

4. 修改listener.ora（紅色部分）：

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = E:\Oracle10g)
      (PROGRAM = extproc)
    )
   (SID_DESC =
    (GLOBAL_DBNAME = ORCL)
    (ORACLE_HOME = E:\Oracle10g)
    (SID_NAME = ORCL)
    )
 )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = onest)(PORT = 1521))
    )
  )
