通过以上信息,可以的出来以下结论:
1. 客户的硬件或者文件系统可能有问题,通过系统日志进一步确认底层异常

2. 数据库在强制拉库的时候,很可能是屏蔽了一致性,导致文件头scn过小
3. 在resetlogs之前,先offline了83号文件,这个将导致该文件的reseltogs scn和其他文件不一致,通过Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)
这个库由于客户在resetlogs之前offline了数据文件,导致一些麻烦,先使用Oracle Recovery Tools修改resetlogs scn
然后重建ctl,修改scn,打开数据库
hcheck检测字典一切正常
