教你怎么修改oracle默认监听端口？

主要是修改两个文件和修改oracle参数local_listener

1 查看当前监听状态

[oracle@test ~]$ lsnrctl status
LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 05-JUL-2018 14:26:26

STATUS of the LISTENER
------------------------

2 关闭监听

[oracle@test ~]$ lsnrctl stop
 
LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 05-JUL-2018 14:29:30

3 修改监听端口号

端口修改为2345，主要修改$ORACLE_HOME/network/admin/目录下的两个文件，listener.ora和tnsnames.ora
修改PORT
 (ADDRESS = (PROTOCOL = TCP)(HOST = 10.162.4.68)(PORT = 2345))

[oracle@test admin]$ cd $ORACLE_HOME/network/admin/
[oracle@test admin]$ vim listener.ora
[oracle@test admin]$ cat listener.ora
# listener.ora Network Configuration File: /data/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
 
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /data/app/oracle/product/11.2.0/dbhome_1)
      (PROGRAM = extproc)
    )
  )
 
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.162.4.68)(PORT = 2345))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
  )
 
#----ADDED BY TNSLSNR 11-APR-2018 16:08:51---
PASSWORDS_LISTENER = 313DBE5E70EB94B5
#--------------------------------------------
[oracle@test admin]$ vi tnsnames.ora
[oracle@test admin]$ cat tnsnames.ora
DWCA =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.162.4.68)(PORT = 2345))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = dwca)
    )
  )
 
EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )
LISTENER_DWCA =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

4 修改初始化参数local_listener

[oracle@test admin]$ sqlplus / as sysdba;
 
SQL*Plus: Release 11.2.0.1.0 Production on Thu Jul 5 14:38:41 2018

SQL> show parameter local_listener;
 
NAME                     TYPE     VALUE
------------------------------------ ----------- ------------------------------
local_listener                 string     LISTENER_DWCA
 
SQL>   alter system set local_listener="(address=(protocol=tcp)(host=10.162.4.68)(port=2345))";
 
System altered.

5 重新开启监听

[oracle@test admin]$ lsnrctl start

6，更换主机并做连接测试

[oracle@test02 ~]$ sqlplus scott/scott@10.162.4.68:2345/dwca
