MAXIMIZE PROTECTION ：最大数据保护与无数据分歧，LGWR将同时传送到备用节点，在主节点事务确认之前，备用节点也必须完全收到日志数据。在主节点与备用节点的网络断开或连接不正常时，主节点的操作还是可以继续的。9i在配置DATA GUARD的时候默认就是MAXIMIZE PERFORMANCE建立备用服务器有如下要求：1、 主节点必须运行在归档模式下2、 主节点与备用节点最好有相同的OS版本，一般beta号差一点还是可以的3、 主节点与备用节点必须有相同的数据库版本和兼容版本。<img src ="aggbug/1562415.aspx" width = "1" height = "1" />Fri, 13 Apr 2007 01:29:00

2、备份策略及恢复以rman多级增量备份来作为备份策略例子:增量备份都需要一个0级备份来作为基础，0级备份与全备份的区别在于0级可以用来增量恢复，而全备份可不可以。<img src ="aggbug/1553841.aspx" width = "1" height = "1" />Fri, 06 Apr 2007 18:21:00
