修改Oracle默认监听端口

我们都知道，Oracle的监听默认端口是1521，但是如果系统上1521已经被占用或业务要求不用默认端口，则需要修改监听的默认端口。

修改监听端口只需要修改配置文件listiner.ora，然后重启监听就行了。但是Oracle实例的PMON进程还是会去找监听1521端口的监听进程去注册，所以同时也需要修改数据库的配置。数据库里只需要在线修改LOCAL_LISTINER即可。

下面以11.2.0.4为例测试修改监听端口：

1、修改监听端口

#查看监听状态[oracle@rhel6 ~]$ lsnrctl statusLSNRCTL for Linux: Version 11.2.0.4.0 - Production on 07-JAN-2017 20:16:24Copyright (c) 1991, 2013, Oracle.

(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=0.0.0.0)(PORT=2521)))  (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=extproc)))The listener supports no servicesThe command completed successfully

至此，监听端口已经修改完毕，这时Oracle实例是无法注册到此监听上的。

2、修改LOCAL_LISTINER参数

#修改参数sys@ORCL>alter system set local_listener="(address = (protocol = tcp)(host = rhel6)(port = 2521))";System altered.#查看监听状态[oracle@rhel6 ~]$ lsnrctl statusLSNRCTL for Linux: Version 11.2.0.4.0 - Production on 07-JAN-2017 20:23:10Copyright (c) 1991, 2013, Oracle.  All rights reserved.Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=0.0.0.0)(PORT=2521)))STATUS of the LISTENER------------------------Alias                     LISTENERVersion                   TNSLSNR for Linux: Version 11.2.0.4.0 - ProductionStart Date                07-JAN-2017 20:19:11Uptime                    0 days 0 hr. 3 min. 59 secTrace Level               offSecurity                  ON: Local OS AuthenticationSNMP                      OFFListener Parameter File   /u02/app/oracle/product/11.2.4/db1/network/admin/listener.oraListener Log File         /u02/app/oracle/diag/tnslsnr/rhel6/listener/alert/log.xmlListening Endpoints Summary...  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=0.0.0.0)(PORT=2521)))  (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=extproc)))Services Summary...Service "orcl" has 1 instance(s).  Instance "orcl", status READY, has 1 handler(s) for this service...The command completed successfully

修改完后，可以看到数据库实例立即注册到监听器上。

3、使用新端口进行测试连接

[c:\~]$ sqlplus zx/zx@192.168.56.2:2521/orclSQL*Plus: Release 12.1.0.1.0 Production on 星期六 1月 7 20:24:17 2017Copyright (c) 1982, 2013, Oracle.  All rights reserved.连接到: Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit ProductionWith the Partitioning, OLAP, Data Mining and Real Application Testing optionsSQL>

修改监听端口完成。

4、把Oracle实例的注册端口改回1521

sys@ORCL>alter system set local_listener='';System altered.

官方文档中还提供了另一种配置LOCAL_LISTINER的方法：

在tnsnames.ora中添加配置，然后配置LOCAL_LISTINER为tnsnames.ora中的名字即可

#配置tnsnames.ora[oracle@rhel6 admin]$ vi tnsnames.ora listener1=(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.56.2 )(PORT = 2521))#修改LOCAL_LISTINER参数sys@ORCL>alter system set local_listener=listener1;System altered.#查看监听状态[oracle@rhel6 ~]$ lsnrctl statusLSNRCTL for Linux: Version 11.2.0.4.0 - Production on 07-JAN-2017 20:34:01Copyright (c) 1991, 2013, Oracle.

Instance "orcl", status READY, has 1 handler(s) for this service...The command completed successfully

另外还可以使用静态监听的方法来修改监听的端口，但是Oracle实例不是"主动"注册到监听器上的。

sys@ORCL>show parameter local_listenerNAME                                 TYPE                             VALUE------------------------------------ --------------------------------- ------------------------------local_listener                       string#修改监听为静态监听[oracle@rhel6 admin]$ vi listener.oraLISTENER=  (DESCRIPTION=    (ADDRESS_LIST=      (ADDRESS=(PROTOCOL=tcp)(HOST=0.0.0.0)(PORT=2521))      (ADDRESS=(PROTOCOL=ipc)(KEY=extproc))))SID_LIST_LISTENER=  (SID_LIST=    (SID_DESC=      (GLOBAL_DBNAME=orcl)      (ORACLE_HOME=/u02/app/oracle/product/11.2.4/db1)      (SID_NAME=orcl))#重启监听[oracle@rhel6 ~]$ lsnrctl stopLSNRCTL for Linux: Version 11.2.0.4.0 - Production on 07-JAN-2017 20:38:45Copyright (c) 1991, 2013, Oracle.

静态监听实例的状态为UNKNOWN，测试连接成功
