1.该用户程序是从8i升级到9i之后产生该错误
2.报错的访问程序是FORM 5

解决方案
查询MOS[ID 273411.1]发现是因为FORM 5和9i不兼容导致该错误,ORACLE未给出解决方案,言外之意,如果FORM不能升级,那就只能把ORACLE重新降级到8i.

温馨提示
在做oracle数据库升级前,需要实现进行评估,测试,如果是oracle相关软件和oracle数据库结合紧密,升级前最好需要和ORACLE技术人员确认是否兼容.

using backup controlfile 两种使用情况区别

1.通过resetlogs使得试验更加清晰
2.通过多次的checkpoint实现增加scn,switch logfile实现日志组切换
3.通过模拟备份控制文件恢复

通过这里可以看出来:
datafile header的Checkpointed scn(00205545)>controfile datafile的Checkpoint scn(002053b4)
datafile header的checkpiont count(760)>controfile datafile的checkpiont count(752)
所以在数据库open的时候会报ORA-01207错误

因为数据库处于非归档模式,而得到的redo信息主要都是来自控制文件,所以只能通过dump redo来分析当前redo的情况

通过对redo dump的分析可以得到：
1.最小的sequence#=3是redo03.log
2.current redo为redo02.log
