做了个迁移表空间的实验，过程如下：

Source DB: 10.2.0.1.0/Linux -32

Target DB: 10.2.0.2.0/Windows -32

新建测试用的表空间 tb1：

SQL> create tablespace tb1 datafile '/oradata/test/tb1_01.dbf' size 50M autoextend off;

Tablespace created

新建测试用的索引表空间Index1：

SQL> create tablespace index1 datafile '/oradata/test/index1_01.dbf' size 50M autoextend off;

Tablespace created

SQL>
SQL>

新建测试帐户：
SQL>
SQL> create user ct identified by "test" default tablespace tb1 quota unlimited on tb1;

User created

SQL> alter user ct quota unlimited on index1;

User altered

SQL> grant resource,connect to ct;

Grant succeeded

用测试帐户登陆：

SQL> conn ct/test@test
Connected to Oracle Database 10g Enterprise Edition Release 10.2.0.1.0
Connected as ct

SQL> create table table1 ( a int,b int );

Table created

增加主健约束：

SQL> alter table table1 add primary key(a);

Table altered

SQL> select * from user_objects;

在Index1表空间上重建索引：

SQL> alter index SYS_C005143 rebuild tablespace index1 online;

插入数据：

SQL> insert into table1 values(0,0);

1 row inserted

SQL> insert into table1 values(1,1);

1 row inserted

SQL> insert into table1 values(2,2);

1 row inserted

SQL> insert into table1 values(3,3);

Commit complete

用SYSDBA连接源数据库：

SQL> conn sys/admin@test as sysdba
Connected to Oracle Database 10g Enterprise Edition Release 10.2.0.1.0
Connected as SYS

SQL>
SQL>

将tb1和index1表空间置为只读：
SQL> alter tablespace tb1 read only;

Tablespace altered

SQL> alter tablespace index1 read only;

Tablespace altered

SQL>
SQL>

新建directory：

SQL> create or replace directory dump_dir as '/oradata/test/dump';

Directory created

将directory的读写权限赋予public：

SQL> grant read on directory dump_dir to public;

Grant succeeded

SQL> grant write on directory dump_dir to public;

Grant succeeded
