【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

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

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。
