Table Recovery using RMAN in oracle 12C

Step 1:

Login as sysdba:
Sqlplus ‘/as sysdba’
Connected to:
Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 – 64bit Production
With the Partitioning, OLAP, Advanced Analytics and Real Application Testing  options

The Table is created on 23rd Jan 2018
Here we taken every day 9pm database full backup.

SQL> select count(*) from sam.kk;

COUNT(*)
——–
100000

Step 2:
 
Check the Current Date and Time:
—————————————–
SELECT TO_CHAR (SYSDATE, ‘MM-DD-YYYY HH24:MI:SS’) “NOW” FROM DUAL;

    NOW
——————-
01-24-2018 20:12:50

Step 3:

DROP A TABLE:
————-
SQL> drop table sam.kk purge;
Table dropped.

Note :
In this Scenario We can Easily Recover the dropped table using RMAN.

Table owner name : sam
Table name            : kk

Step 4:
