It is always very easy to resign, so today I am doing a 1z0-042 question bank. The correct answer is that truncate can generate a small number of redo operations, let me test it.
Step 1 create a table
1 Create TableTestAs Select * FromDba_objects;
Step 2: Calculate the redosize
SelectName, ValueFromV $ sysstatWhereA. Name= 'Redo size';
Redo size: 32378840.
Step 3 truncate the table and then count the redo size
Truncate TableTest1;

is based on the Fermat theorem and the two-time detection theorem:
Two-time detection theorem: If P is an odd prime, then the solution for X2≡1 (MODP) is x = 1 or x = p-1 (mod p)
So we can turn X into the R*2^t form, where R is an oddThen we combine two algorithms fast power to stabilize O (log x) for a single judgmentBut this algorithm is a non-perfect algorithm , every time it is 25% probability is wrong, so we can choose a few numbers to get a few timesBut by chance I see a pa
