如何从完好的数据文件恢复oracle数据库

核心提示： background_dump_dest=c:\demo\bdump core_dump_dest=c:\demo\cdump user_dump_dest=c:\demo\udump control_files=(&quo

　background_dump_dest=c:\demo\bdump
core_dump_dest=c:\demo\cdump
user_dump_dest=c:\demo\udump
control_files=("c:\demo\oradata\demo\CONTROL01.CTL", "c:\demo\oradata\demo\CONTROL02.CTL", "c:\demo\oradata\demo\CONTROL03.CTL")
dispatchers="(PROTOCOL=TCP) (SERVICE=demoXDB)"(实例名)
dispatchers="(PROTOCOL=TCP) (SERVICE=demoXDB)"
db_domain=""
db_name=demo
　

3.创建oracle服务和口令文件

C：\documents and settings\oradim — new —sid demo —intpwd oracle

4.配置监听和服务

用net manager 进行配置（demo实例的配置）

5.复制数据文件备份到指定的目录下。此处为c：\demo\oradata\demo

6.重建controlfile 　C:\Documents and Settings\hefan>sqlplus /nolog

说明：此时没有日志文件，所以只能进行reserlogs,如果是有logfile，则此处不需要resetlogs，noresetlogs就可以
