关于ip变化导致oracle不能登录的解决
百试百灵，just do it——> D:\oracle\product\10.2.0\db_2\NETWORK\ADMIN
将下列两个文件，改为本机ip地址：
listener.ora
tnsnames.ora
运行lsnrctl start启动监听 <!--lsnrctl stop关闭监听程序-->
再等一分钟不到就可以登录了！
附：listener.ora打开后的内容：
# listener.ora Network Configuration File: d:\oracle\product\10.2.0\db_2\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME =PLSExtProc)
(ORACLE_HOME = d:\oracle\product\10.2.0\db_2)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST =10.2.104.168)引用就是这里啦，将HOST改为当前主机IP!(PORT = 1521))
)
)
