You are working in an online transaction processing (OLTP) environment. You use the
FLASHBACKTABLE command to flash back the CUSTOMERS table. Before executing the
FLASHBACK TABLE command, the system change number (SCN) was 663571. After flashing
back the CUSTOMERS table, you realize that the table is not in the correct state. Now, you need
to reverse the effects of the FLASHBACK TABLE command. Which is the fastest and the most
efficient option to reverse the effects of the FLASHBACK TABLE command?
A.
Restore the backup control file and open the database with RESETLOGS option.
B.
Perform point-in-time recovery because flashback cannot be performed again on this table
C.
Execute the FLASHBACK DATABASE statement to retrieve the CUSTOMERS table as it was
at SCN 663571
D.
Execute another FLASHBACK TABLE statement to retrieve the CUSTOMERS table as it was
at SCN 663571
Explanation:
Undoing a Flashback Table Operation
It is important to note your current SCN before using a Flashback Table operation.
Use the FLASHBACK TABLE statement again to go back to just before you were when you issued
the first statement.
