rman基于TSPITR恢复drop掉的表空间

rman基于TSPITR恢复drop掉的表空间

  今天是2013-11-24，在11.2之前无法使用tspitr技术恢复drop掉的表空间，但是到了11.2这个限制已经没有了。

测试如下：

SQL> select file_name from dba_data_files;

FILE_NAME
--------------------------------------------------------------------------------
/opt/app/oracle/oradata/RHYS/users01.dbf
/opt/app/oracle/oradata/RHYS/undotbs01.dbf
/opt/app/oracle/oradata/RHYS/sysaux01.dbf
/opt/app/oracle/oradata/RHYS/system01.dbf

/*创建表空间*/

SQL> create tablespace test datafile '/opt/app/oracle/oradata/RHYS/test.dbf' size 10M;

Tablespace created.
SQL> create user Amy identified by Rhys default tablespace test;

User created.

SQL> grant resource,create session to Amy;

Grant succeeded.
SQL> create table t as select * from scott.emp;

Table created.

SQL> commit;

Commit complete.
SQL> select sequence#,status from v$log where status='CURRENT';

 SEQUENCE# STATUS
---------- ----------------
        44 CURRENT

SQL> r
  1* insert into t select * from t

14336 rows created.

SQL> r
  1* insert into t select * from t

28672 rows created.

SQL> r
  1* insert into t select * from t

57344 rows created.

SQL> select count(*) from dba_objects;

  COUNT(*)
----------
     86369

SQL>
SQL> alter system switch logfile;

System altered.

SQL> r
  1* alter system switch logfile

System altered.
SQL> select sequence#,status from v$log where status='CURRENT';

 SEQUENCE# STATUS
---------- ----------------
        47 CURRENT
