1、查看jzh用户下对象
JZH@jzh>select * from tab;
TNAME TABTYPE CLUSTERID
------------------------------ ------- ----------
JZH1 TABLE
T TABLE
TEST TABLE
TEST1 TABLE
2、创建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、导出数据
[oracle@jzh5 ~]$ expdp jzh/jzh schemas=jzh directory=dir_dmp dumpfile=jzh.dmp

7、查询jzh用户下对象
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';
