重做日志缓冲区 meaning in Chinese

redo log buffer

The entire notion of online backup in oracle is that as users carry out transactions , all changes made to the database , either committed or uncommitted , are stored to the redo log buffer and subsequently are written to the online redo log files by the lgwr process
在oracle中，联机备份的全部思想是，当用户执行事务时，将对数据库所做的所有更改（提交或未提交的）都存储到重做日志缓冲区中，随后由lgwr进程把它们写到联机重做日志文件中。
