目标库：
1、创建测试表空间和用户
SQL> create tablespace LLC datafile '+DATA/phub/datafile/LLC01.dbf' size 5G; Tablespace created. SQL> create user lilc identified by lilc default tablespace LLC; User created. SQL> grant dba to lilc; Grant succeeded. SQL> conn lilc/lilc; Connected. SQL> select DEFAULT_TABLESPACE from dba_users where username='LILC'; DEFAULT_TABLESPACE ------------------------------ LLC
2.创建DIRECTORY
SQL> create or replace directory dir_dp as '/home/oracle/dir_dp'; Directory created.
3.授权
SQL> grant read,write on directory dir_dp to lilc;
4.执行导入：
更换表空间和更换用户导入：
