oracle改变ip后的问题

虚拟环境中，克隆了一台centos，修改ip后，里面以前安装的oracle有问题。

首先修改oracle监听ip

cd  /opt/Oracle/app/oracle/product/12.1.0/dbhome_1/network/admin

修改listener.ora下的ip地址：

# listener.ora Network Configuration File: /opt/Oracle/app/oracle/product/12.1.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.109.71)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)

进入sqlplus，关闭并重启oracle实例

shutdown immediate;

startup;

之后重启监听：

lsnrctl start

启动后报出：

the listener supports no services

尝试如下解决方案：

一、手工注册

SQL> alter system register;
System altered.
注册后重启服务、监听，发现依然不行，服务端仍是：the listener supports no services，客户端连接是：

ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

二、修改 listener.ora

在LISTENER里添加内容：
SID_LIST_LISTENER =

(SID_LIST =
  (SID_DESC =
  (GLOBAL_DBNAME = orcl)
  (SID_NAME = orcl)
  )
)
之后重启监听，问题解决！

另，感觉这是个bug，google下·看到：http://www.askmaclean.com/archives/11gr2-rac-add-listener-static-register.html

原来在11gr2新建和修改监听后，不会自动静态注册，需要退出netca 界面，启动netmgr界面，为监听加入静态注册的信息：

点选方才创建的监听器，选择Database Services菜单
填入Global Database Name和本地实例的SID信息，并确认ORACLE HOME Directory(应是Grid Infrastructure的Home目录)正确后点选Save Network Configuration。
重启监听即可
