Oracle数据库修改LISTENER的监听端口
转自：http://www.cnblogs.com/chenleiustc/archive/2009/07/26/1531529.html
【强调一点】
由于oracle实例的动态注册只能在默认端口1521上运行，端口修改后监听一定要记得修改为“静态注册”方式。
否则您永远也等不到LISTENER动态监听到您的oracle实例！

【修改步骤】
1.修改listener.ora文件，端口从1521修改成1526；同时将监听改为“静态注册”
listener.ora文件修改前：
ora10g@testdb /home/oracle$ cat $ORACLE_HOME/network/admin/listener.ora
# listener.ora Network Configuration File: /oracle/app/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
  )


LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 144.194.192.183)(PORT = 1521)(IP = FIRST))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
  )

listener.ora文件修改后：
ora10g@testdb /home/oracle$ cat $ORACLE_HOME/network/admin/listener.ora
# listener.ora Network Configuration File: /oracle/app/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
    (SID_DESC =   ## 静态注册在这里体现
      (GLOBAL_DBNAME = ora10g)
      (ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)
      (SID_NAME = ora10g)
    )
  )


LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 144.194.192.183)(PORT = 1526)(IP = FIRST)) ## 端口修改在这里体现
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
  )

2.修改tnsnames.ora文件，将其中出现的1521端口号修改为1526
ora10g@testdb /home/oracle$ cat $ORACLE_HOME/network/admin/tnsnames.ora
# tnsnames.ora Network Configuration File: /oracle/app/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

ORA10G =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 144.194.192.183)(PORT = 1526))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ora10g)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

3.重新启动LISTENER
LSNRCTL> stop
LSNRCTL> start
