修改 Oracle 的默认端口

oracle 修改默认端口：
1. 查看状态：

lsnrctl status

, 命令路径：${oracle_home1}\BIN
2. 停止监听：

lsnrctl stop

3. 修改端口：
   文件1： ${oracle_home1}\NETWORK\ADMIN\listener.ora 将数据库实例添加到 SID_LIST
   

SID_LIST_LISTENER =
      (SID_LIST =
        (SID_DESC =
          (SID_NAME = CLRExtProc)
          (ORACLE_HOME = ${oracle_home1})
          (PROGRAM = extproc)
          (ENVS = "EXTPROC_DLLS=ONLY:${oracle_home1}\bin\oraclr11.dll")
        )
        (SID_DESC =
        (GLOBAL_NAME = michael)
          (SID_NAME = michael)
          (ORACLE_HOME = ${oracle_home1})
        )
      )

    LISTENER =
      (DESCRIPTION_LIST =
        (DESCRIPTION =
          (ADDRESS = (PROTOCOL = TCP)(HOST = Michael-WK)(PORT = 1521))
        )
      )

  端口改为 1521， 增加数据库的 sid_list.

  文件2：${oracle_home1}\NETWORK\ADMIN\tnsnames.ora
 

MICHAEL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = michael)
    )
  )

  端口改为 1521

4. 修改数据库配置.
   登录：

sqlplus sys/michael@localhost:5521/michael as sysdba

   修改参数：

alter system set local_listener="(address=(protocol=tcp)(host=localhost)(port=1521))";

5. 启动监听器：

lsnrctl start
