3 修改监听端口号

端口修改为2345，主要修改$ORACLE_HOME/network/admin/目录下的两个文件，listener.ora和tnsnames.ora
修改PORT
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.162.4.68)(PORT = 2345))

[oracle@test admin]$ cd $ORACLE_HOME/network/admin/

[oracle@test admin]$ vim listener.ora

[oracle@test admin]$ cat listener.ora

      (PRESENTATION = RO)

    )

  )
