數據庫imp導表dmp的方法

1>sqlplus / as sysdba 進入sqlplus

2>drop user USER cascade

3>create user USER IDENTIFIED BY PASSWD 建立用戶和密碼

4>GRANT CREATE SESSION TO USER

5>grant dba to USER

6>返回dos,在dos下輸入:imp userid=USER/****@orcl file=c:\src.dmp log=c:\src.log full=y ignore=y

若是須要備份多個dmp方便比較，能夠建立多個userID。備份時候將full模式改爲 fromuser -- touser模式

1>create user "用戶名1" IDENTIFIED BY PASSWD 建立用戶和密碼

2>GRANT CREATE SESSION TO "用戶名1"

3>grant dba to "用戶名1"

4>返回dos,在dos下輸入:imp userid="用戶名1"/密碼1@orcl file=c:\1.dmp log=c:\1.log ignore=y fromuser=dmp的用戶名 touser="用戶名1"

--------------------------------------------

而後重複建立"用戶名2"

1>create user "用戶名2" IDENTIFIED BY PASSWD 建立用戶和密碼

2>GRANT CREATE SESSION TO "用戶名2"

3>grant dba to "用戶名2"

4>返回dos,在dos下輸入:imp userid="用戶名2"/密碼2@orcl file=c:\2.dmp log=c:\2.log ignore=y fromuser=dmp的用戶名 touser="用戶名2"

=============================

fromuser touser模式和full模式不能共存！
