Seema:
Regarding the "Checkpoint not completed." message, make sure you're
checkpointing only at redo log switches.
Check loc_checkpoint_timeout and log_checkpoint_interval values.
If these values are OK and you still keep getting "Checkpoint not
completed." messages in the alert.log
you should enlarge your redo logs.
