Oracle数据库修改LISTENER的监听端口

阅读更多

【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

4.使用ora10g进行测试
ora10g@testdb /home/oracle$ sqlplus sec/sec@ora10g

SQL*Plus: Release 10.2.0.1.0 - Production on Tue Jul 21 16:21:32 2009

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
With the Partitioning, Oracle Label Security, OLAP and Data Mining Scoring Engine options

sec@ora10g>

一切OK，修改成功！



【买一赠一】修改监听端口号后企业管理器（Enterprise Manager）对应的调整
1.修改emoms.properties属性文件中端口信息
ora10g@testdb /home/oracle$ vi $ORACLE_HOME/${HOSTNAME}_${ORACLE_SID}/sysman/config/emoms.properties
这个文件中有两行含有1521端口号的信息，将他们统统的修改为1526
oracle.sysman.eml.mntr.emdRepPort=1521
oracle.sysman.eml.mntr.emdRepConnectDescriptor=(DESCRIPTION\=(ADDRESS_LIST\=(ADDRESS\=(PROTOCOL\=TCP)(HOST\=testdb)(PORT\=1521)))(CONNECT_DATA\=(SERVICE_NAME\=ora10g)))
这两个行修改后的内容如下
oracle.sysman.eml.mntr.emdRepPort=1526
oracle.sysman.eml.mntr.emdRepConnectDescriptor=(DESCRIPTION\=(ADDRESS_LIST\=(ADDRESS\=(PROTOCOL\=TCP)(HOST\=testdb)(PORT\=1526)))(CONNECT_DATA\=(SERVICE_NAME\=ora10g)))

2.修改targets.xml配置文件中端口信息
ora10g@testdb /home/oracle$ vi $ORACLE_HOME/${HOSTNAME}_${ORACLE_SID}/sysman/emd/targets.xml
这个文件中的1521端口号的信息统统的修改为1526

3.重启EM
ora10g@testdb /home/oracle$ emctl stop dbconsole
TZ set to PRC

4.验证EM登陆
在本地浏览器中输入如下的URL
http://144.194.192.183:5500/em/
看到登陆界面了，OK，搞定ed。
