Checkpoint Process (CKPT) (119)

原创 IT综合 作者:tsinglee 时间:2007-10-31 11:02:12 0 删除 编辑

When a checkpoint occurs, Oracle must update the headers of all datafiles to record
the details of the checkpoint. This is done by the CKPT process. The CKPT process
does not write blocks to disk; DBWn always performs that work.
The statistic DBWR checkpoints displayed by the System_Statistics monitor in
Enterprise Manager indicates the number of checkpoint requests completed.

检查点进程
当检查点发生时 , Oracle将更新所有数据文件的头来记录检查点 .
后面这句话什么意思 ? 哪位大侠告诉我一下 , 谢谢.
