to checkpoint queue.Also when a block is first modified it
is entered in the checkpoint queue.The RBA of redo record

checkpoint queue.In case of instance failure RBA gives the
location from where recovery has to start( Checkpoint
position). During log switch CKPT updates contrl file and
data file headers.
