1.修改数据库名
1.查看oracle实例名
2.shutdown immediate
3.lsnrctl stop $ORACLE_SID#----------windows下关闭使用oracle服务
4.修改 /etc/oratab 的$ORACLE_SID#------------windows没有
5.修改用户环境变量.bashprofile #------------windows没有
6.linux下$ORACLE_HOME/dbs 修改有关$ORACLE_SID的文件名
windows下$ORACLE_HOME/database 修改有关$ORACLE_SID的文件名
7.重新生成密码文件，启动数据库
liunx：orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID password=oracle entries=5 force=y
windows：
在一个cmd运行oracle %ORACLE_ORCL%
在另一个cmd运行
set ORACLE_HOME=E:appcswggodproduct11.2.0dbhome_1database
set ORACLE_ORCL=orcl
orapwd file=%ORACLE_HOME%/ORACLE_HOME/dbs/orapw%ORACLE_SID% password=oracle entries=5 force=y
startup
