Now We will perform the tablespace point in time recovery until the time before the table was dropped.

For TSPITR, we need to specify the auxiliary destination where RMAN would create a temporary database
by restoring the controlfile, SYSTEM tablespace, UNDO tablespace, SYSAUX tablespace and finally the
tablespace that needs to be recovered.Once the temporary database is restored and recovered, RMAN
automatically exports the contents of tablespace to be recovered from the temproary tablespace to a dump
file and imports this dump into the Target(Main) database where the table was dropped.

Recovering A Dropped Table Using Tablespace Point In Time Recovery (TSPITR) in Oracle 11g

Oracle version : 11.2.0.1.0 Enterprise Edition
OS : Rhel 6.4
Database Name : orcl
Tablespace Name : TESTTBS

A user reported a table named "TSPITR" was accidentally dropped . There was no flashback enabled on this
database and the recyclebin too was purged out. As a result, the table could not be recovered using
flashback method. The other methods to recover the dropped table would be:

Using Tablespace Point In Time Recovery. Here, the tablespace associate with the table that is dropped
would be recovered until the time. The main disadvantage of this method is that any other successful
transactions that were carried out on this tablespace after the time the
table was dropped, would be lost when you do a point in time recovery.

Here we are trying to create the same scenario by creating and dropping the table TSPITR.

sqlplus soumya/soumya

SQL> create table xyz (id number);
SQL> insert into xyz values (1);
1 row created.
SQL> /
1 row created.
SQL> /
1 row created.
SQL> /
1 row created.
SQL> /
1 row created.
SQL> /
1 row created
SQL> commit;


First lets find out the tablespace where the table resides:-
SQL> select table_name ,tablespace_name from user_tables where table_name ='XYZ';

TABLE_NAME               TABLESPACE_NAME
------------------------------ ------------------------------
XYZ                                 TESTTBS

SQL> SELECT * FROM xyz;

        ID
----------
         1
         1
         1
         1
         1
         1

SQL> select to_char(sysdate,'DD-MON-YYYY HH24:MI:SS') from dual;

TO_CHAR(SYSDATE,'DD-MON-YYYYH
-----------------------------
20-SEP-2014 07:22:29

*Make sure that you have a valid RMAN level 0 backup to proceed.
Now lets drop the table and purge recyclebin too.

SQL> drop table xyz;

Table dropped.

SQL> purge recyclebin;

Recyclebin purged.

SQL> select * from xyz;
select * from xyz
              *
ERROR at line 1:
ORA-00942: table or view does not exist

Now We will perform the tablespace point in time recovery until the time before the table was dropped.

For TSPITR, we need to specify the auxiliary destination where RMAN would create a temporary database
by restoring the controlfile, SYSTEM tablespace, UNDO tablespace, SYSAUX tablespace and finally the
tablespace that needs to be recovered.Once the temporary database is restored and recovered, RMAN
automatically exports the contents of tablespace to be recovered from the temproary tablespace to a dump
file and imports this dump into the Target(Main) database where the table was dropped.

Once the import is done successfully, RMAN automatically deletes the temporary database that it had
created earlier.Now, lets connect to the main database and check if we are able to access the dropped
table. But, before that, we need to bring the tablespace online.


SQL>  set linesize 100
SQL> col name for a60
SQL> select name,status from v$datafile;

NAME                                                         STATUS

We can notice that the tablespace TESTTBS and TS_HYBRIS_DATA are offline. Before proceeding, this
tablespaces needs to be made online.

QL> alter tablespace TS_HYBRIS_DATA online;

Tablespace altered.

SQL> alter tablespace testtbs online;

Tablespace altered.

SQL> select tablespace_name,status from dba_tablespaces;

TABLESPACE_NAME                STATUS

Finally we can see the dropped table is back with its data inside it.
