updating the table causes lmode to 3

Hello,

When I update few rows using where clause then lmode shows as 3 in v$lock.

When I execute below statement then I think lock escalation should happen and lmode should be 6 since we are updating whole table and this should be table lock in exclusive instead maintaining so many locks for rows isn't it however this still shows as 3?

SQL> update t1 set t1=2,t2=10;

Best regards,
