Question

我有从损坏的分区中恢复的数据文件。请帮我将它们恢复到新的Oracle数据库中。我是Oracle的新手，所以这个任务对我来说太难了。我真的需要你的帮助！

Answer 1

假设您复制这些文件时数据库已关闭。

将所有原始数据文件备份到其他位置并将所有* .dbf文件复制到datafile文件夹中

尝试使用以下命令

SQL> conn / as sysdba
Connected.
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL>

 SQL> startup nomount;
 SQL> alter system set control_files = '/oracle/data/control.dbf';
 SQL> shutdown immediate

SQL> startup mount
ORACLE instance started.
