修改oracle 监听端口号，过程相对比较简单：
1 修改 listener.ora ,tnsnames.ora 文件中的端口号
2 重启监听 lsnrctl stop ，lsnrctl start
上面的过程是对于 监听名为默认的LISTENER 而言的，如果listener.oar文件中的监听名不是默认的，就重启时必须指定监听名。比如将端口号由1521改为1523
oracle@rac3:/opt/oracle/11.2.0/alifpre/network/admin>vi listener.ora
# listener.ora Network Configuration File: /opt/oracle/11.2.0/alifpre/network/admin/listener.ora
# Generated by Oracle configuration tools.
yangdb =

(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac3)(PORT = 1523))
)

ADR_BASE_LISTENER = /opt/oracle
oracle@rac3:/opt/oracle/11.2.0/alifpre/network/admin>vi tnsnames.ora
# tnsnames.ora Network Configuration File: /opt/oracle/11.2.0/alifpre/network/admin/tnsnames.ora

重启监听：

如启动的时候 不指定监听名称，默认为LISTENER 且端口也是默认的 1521
