Since the buffer status in write lists may be converted and there is no time order, that is, if the buffer is written to the disk according to this lists, the sequence is not consistent with the time sequence of buffer changes. This also directly results in checkpoints fully refresh dirty buffer in versions earlier than Oracle 8. That is to say, when a checkpoint occurs, all dirty bu

may also indicate that no selected SQL statements cause data to overflow the buffer memory with index blocks, and no buffer is left for specific statements waiting for system processing. This usually indicates that a considerable amount of DML (insert, update, and delete) is being executed, and the database writer (dbwr) write speed is not fast enough, buffer memory may be filled with multiple versions of the same buffer, resulting in very low efficiency. To solve this problem, you may need to
