RMAN传输表空间迁移数据

实验环境:
源数据库:oracle 10g(Release 10.2.0.1.0)
目标数据库:oracle 10g(Release 10.2.0.1.0)
待传输的表空间:TEST
1.在test(默认表空间是TEST)用户下面创建一张test表。
SQL> select * from tab;

no rows selected

SQL> create table test (id int primary key)
  2  ;

Table created.

SQL> insert into test values(1);

1 row created.

SQL> insert into test values(2);

1 row created.

SQL> insert into test values(3);

1 row created.

SQL> show user;
USER is "TEST"
SQL> commit;

Commit complete.
在传输之前:
(1)确认平台是否支持:若是不同平台需要检查平台版本及Endian Format。
SQL> exec DBMS_TTS.TRANSPORT_SET_CHECK('test',true);
BEGIN DBMS_TTS.TRANSPORT_SET_CHECK('test',true); END;

      *
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00201: identifier 'DBMS_TTS.TRANSPORT_SET_CHECK' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored


SQL> conn sys/oracle as sysdba
Connected.
SQL> exec DBMS_TTS.TRANSPORT_SET_CHECK('test',true);

PL/SQL procedure successfully completed.

SQL> select * from transport_set_violations;

no rows selected
严格方式验证:
SQL> exec DBMS_TTS.TRANSPORT_SET_CHECK('test',true,true);

PL/SQL procedure successfully completed.

SQL> select * from transport_set_violations;

no rows selected

3.
(1)
SQL> conn test/oracle
Connected.

SQL> select username,default_tablespace from user_users;

USERNAME                       DEFAULT_TABLESPACE
------------------------------ ------------------------------
TEST                           TEST

SQL> conn sys/oracle as sysdba
Connected.
SQL> alter tablespace test read only;

Tablespace altered.
