1 数据文件头部和恢复相关的几个偏移量说明:
ub4 kcvfhcpc @140 0x00000308------检查点计数
ub4 kcvfhccc @148 0x00000307------总是比检查点计算少1
ub4 kcvcptim @492 0x2f9af923-----检查点时间
ub4 kscnbas @484 0x8013ea80-------- scn的低位
ub2 kscnwrp @488 0x0000--------- scn的高位
ub4 kcvfhrlc @112 0x2f9af2a9------resetlogs count
struct kcvfhrls, 8 bytes @116
ub4 kscnbas @116 0x8013e6b3-------- resetlogs scn
ub2 kscnwrp @120 0x0000
如果是resetlogs 方式打开数据库对于recover失败的数据文件其数据文件中偏移量 @140、@148、@492、@484、@112、@116应该和其它不需要恢复的数据文件保持一致
其它情况数据文件中偏移量 可能仅需要@140、@148、@492、@484和其它不需要恢复的数据文件保持一致
