以orcl實例為例子:在此實例下頻繁的刪除更新數據庫.
1 打開cmd窗口
2 命令sqlplus
3 輸入用戶名: conn / as sysdba 密碼:*****
4 如果有orcl那么刪除
drop user orcl cascade;
5 創建orcl並授權
create user orcl identified by orcl account unlock;
grant connect,dba,imp_full_database to orcl;
6 打開新的cmd窗口 輸入導入命令
imp orcl/orcl@orcl full=yes file=D:\jddatabak\20180413_linux_0.dmp
