While doing flashback on a table, got below error:

 
17:13:10 SQL> flashback table dbaclass.DEP_TAB to timestamp sysdate – 1/144;
flashback table dbaclass.DEP_TAB to timestamp sysdate – 1/144
*
ERROR at line 1:
ORA-08189: cannot flashback the table because row movement is not enabled

 

Solution:

To flashback a table, we need to enable row movement.

Now run flashback again.
