摘要 LSN是重做日志记录的物理地址,主要讨论LSN的构成以及在SQL Server实例恢复过程中由LSN定位日志记录的机制,并说明实例恢复过程中的前滚和回滚操作如何确定对数据文件应用重做日志记录的范围,对日志记录中记载的主要内容及checkpoint的功能也做阐述。 LSN is the physical address of redo log record, discusses the components of LSN and the mechanism of log record locating in SQL Server recovery using LSN, and how redo and undo operations determine the redo log range applied on data files, also mentions the contents of redo log and the functions of checkpoint.
