1、檢視jzh使用者下物件
JZH@jzh>select * from tab;
TNAME TABTYPE CLUSTERID
------------------------------ ------- ----------
JZH1 TABLE
T TABLE
TEST TABLE
TEST1 TABLE
2、建立directory
SYS@jzh>create directory dir_dmp as '/home/oracle';
Directory created.
SYS@jzh>grant read,write on directory dir_dmp to public;
Grant succeeded.
3、匯出資料
[oracle@jzh5 ~]$ expdp jzh/jzh schemas=jzh directory=dir_dmp dumpfile=jzh.dmp

7、查詢jzh使用者下物件
JZH@jzh>select * from tab;
TNAME TABTYPE CLUSTERID
------------------------------ ------- ----------
JZH1 TABLE
T TABLE
TEST TABLE
TEST1 TABLE
JZH@jzh>select index_name from user_indexes where table_name='JZH1';
INDEX_NAME
------------------------------
PK_JZH1
----表與索引回來了
總結：imdp不但自動建立了使用者，而且密碼與原來一樣。
