Recover truncate table using RMAN tablespace point in time recovery

Here I’m go to demonstrate How do we recover truncate table using RMAN tablespace point in time recovery.

I hope This post may very user friendly for you without confusion 🙂

Step 1:  Create tablespace and allocate one user for this tablespace 

SQL> create tablespace rmantbs datafile 'c:\temp\rmnatbs01.dbf' size 100m;

Tablespace created.

SQL> create user rmantbs identified by rmantbs default tablespace rmantbs;

User created.

SQL> grant connect,resource to rmantbs;

Grant succeeded.

SQL> grant read,write on directory data_pump_dir to rmantbs;

Grant succeeded.

 

Step 2: Create another one tablespace and allocated another new user which one checking data lost will happen or not after TBPITR recovery done.

SQL> create tablespace rmantest datafile 'c:\temp\rmantest01.dbf' size 50m;

Tablespace created.

SQL> create user rmantest identified by rmantest default tablespace rmantest;

User created.

SQL> grant connect,resource to rmantest;

Grant succeeded.

Step 3: Create two table and insert few rows

SQL> set time on
21:12:02 SQL> conn rmantbs/rmantbs
Connected.
21:12:25 SQL> create table employee(empno number,empname varchar2(20));

Table created.

21:13:20 SQL> insert into employee values(001,'azar');

1 row created.

21:13:36 SQL> insert into employee values(002,'jabar');

1 row created.

21:13:45 SQL> insert into employee values(003,'kareem');

1 row created.

21:13:54 SQL> insert into employee values(004,'ajmal');

1 row created.

21:14:08 SQL> commit;

Commit complete.

21:14:11 SQL> create table empcity(cityname varchar2(20));

Table created.

21:14:41 SQL> insert into empcity values('riyadh');

1 row created.

21:14:53 SQL> commit;

Commit complete.

Step 4: create anothe one table for rmantest user which allocated rmantest tablespace.

:55 SQL> conn rmantest/rmantest
Connected.
21:15:01 SQL> create table a(empno number);

Table created.

21:15:14 SQL> insert into a values(001);

1 row created.

21:15:24 SQL> insert into a values(002);

1 row created.

21:15:29 SQL> insert into a values(003);

1 row created.

21:15:39 SQL> insert into a values(004);

1 row created.

21:15:42 SQL> commit;

Commit complete.

Step 5: Switch logfile

21:15:44 SQL> conn / as sysdba
Connected.
21:15:53 SQL> alter system switch logfile;

System altered.

Step 6: Backup database with archivelog

RMAN> backup database plus archivelog;

Step 7:  Note Current Timestamp before truncate table

21:16:23 SQL> select current_timestamp from dual;

CURRENT_TIMESTAMP
---------------------------------------------------------------------------
25-APR-11 09.21.30.293000 PM +03:00 21:21:30 SQL> conn rmantbs/rmantbs
Connected.
21:21:49 SQL> select * from employee;

     EMPNO EMPNAME
---------- --------------------
         1 azar
         2 jabar
         3 kareem
         4 ajmal

21:22:13 SQL> truncate table employee;

Table truncated.

Step 8: Insert some few rows for another one table which is usefull for whether data loss or not and also How do we preserve these data.

21:25:16 SQL> insert into empcity values('chennai');

1 row created.

21:27:14 SQL> insert into empcity values('trichy');

1 row created.

21:27:22 SQL> insert into empcity values('dammam');

1 row created.

21:27:33 SQL> conn rmantest/rmantest
Connected.
21:27:44 SQL> insert into a values(005);

1 row created.

21:27:53 SQL> commit;

Commit complete.

Step 9: Before you done tbpitr, you must check Determine and Resolved Dependencies

21:27:59 SQL> conn / as sysdba
Connected.
21:35:14 SQL> SELECT * FROM sys.ts_pitr_check WHERE(ts1_name = 'RMANTBS' AND ts2
_name != 'RMANTBS')  OR (ts1_name != 'RMANTBS' AND ts2_name = 'RMANTBS');

no rows selected

Step 10 : Determine Which Objects Will Not Be Recovered

For objects in tablespaces involved with the TSPITR, you’ll lose any transactions that were

created prior to the point to which you restore. If you need to preserve objects created after

the time to which you are going to restore, then you’ll need to use the Datapump or Export utility to save them.

After you have performed TSPITR, then you can import these objects.

21:36:47 SQL> SELECT owner, name, tablespace_name FROM ts_pitr_objects_to_be_dro
pped WHERE tablespace_name ='RMANTBS' AND creation_time > to_date('25-APR-11 09.
21.30','DD-MON-RRRR HH24:MI:SS');

OWNER                          NAME
------------------------------ ------------------------------
TABLESPACE_NAME
------------------------------
RMANTBS                        EMPLOYEE
RMANTBS

RMANTBS                        EMPCITY
RMANTBS

More details about See metalink ID TSPITR:How to check dependency of the objects and identifying objects that will be lost after TSPITR [ID 304308.1]

Step 11: Export the above two tables data for safe purpose.But Here Employee table not need, only EMPCITY table enough for export, However I exported two tables

 Step 13 : After done it, Backup tablespace

RMAN>backup tablespace rmantbs;

Step 14: tablespace online

21:54:34 SQL> alter tablespace rmantbs online;

Tablespace altered.

Step 15:  Check whether truncate table recovered or not

:44 SQL> conn rmantbs/rmantbs;
Connected.
21:54:52 SQL> select * from employee;

     EMPNO EMPNAME
---------- --------------------
         1 azar
         2 jabar
         3 kareem
         4 ajmal

Now It was recovered.

Step 16: Now I’m going to check another table whether inserted data availble after done TBPITR time

21:55:01 SQL> select * from empcity;

CITYNAME
--------------------
riyadh

Not availble, So in this case I’m going to import this table data from dumpfile , this dumpfile taken before I do TBPITR

Step 17: Import table
