【LISTENER】修改 LISTENER的监听端口为1526（静态注册）

强调一点】

动态注册默认只注册到默认的监听器上(名称是LISTENER、端口是1521、协议是TCP)，如果需要向非默认监听注册，则需要配置local_listener参数。

此文不讨论通过设置local_listener参数完成监听的的动态注册。我们将采用“静态注册”的方法来完成监听端口的调整。

【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 NetworkConfiguration File:/oracle/app/oracle/product/10.2.0/db_1/network/admin/listener.ora

# Generated by Oracleconfiguration 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 NetworkConfiguration File:/oracle/app/oracle/product/10.2.0/db_1/network/admin/listener.ora

# Generated by Oracleconfiguration 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 NetworkConfiguration File:/oracle/app/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora

# Generated by Oracleconfiguration 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

4.使用“ora10g”进行测试

ora10g@testdb /home/oracle$sqlplus sec/sec@ora10g

一切OK，修改成功！

5.小结

使用“静态注册”方法修改监听端口的步骤如下：

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”；

2）修改tnsnames.ora文件，将其中出现的1521端口号修改为1526；

3）重新启动LISTENER；

4）测试。
