The incremental checkpoint is used to balance the load. It is triggered by the fast_start_mttr_target parameter and is incrementally written out. Therefore, CHECKPOINT_CHANGE # is delayed and will not be updated immediately.Three methods are used to prove the problem:Method 1:Theory: logs are active, that is, logs overwritten by RBA pointers. If the checkpoint is complete, RBA will immediately redo the last entry of the log group. Without RBA, the log state is inactive. If the checkpoint is incr
