由于虚拟化环境使用了精简模式(预分配),后面出现分布式存储空间不足,导致虚拟化环境中的数据库服务器异常,通过一系列操作恢复好系统,发现数据库无法open,请求我们给予解决
通过我们的Oracle Database Recovery Check脚本分析,分析文件的checkpoint scn 有部分3月2日,还有一些是2月28日,是严重不一致,而且对应的归档也丢失

基于这样的情况,试试看强制打开库

 使用_allow_resetlogs_corruption导致ORA-00704/ORA-01555故障

一般情况下会报某个回滚段,但是这里ORA-01555: snapshot too old: rollback segment number 0 with name “SYSTEM” too small这里直接报了system(系统回滚段),属于少见情况

出现这类问题,一般是由于obj$,seq$,undo$等基表上对象scn大于数据库当前scn或者是由于这些表上有事务未提交,出现上述两种情况,数据库需要找对应的undo的回滚段中记录,而此时对应的回滚段异常(或者是由于redo未进行正常前滚,导致上述对象或者回滚段记录不正常),从而出现类似情况,一般出现此类情况,可以通过10046定位到block，然后故障原因采用bbed修改scn或者bbed提交事务来解决此类问题.
最近两年的恢复中又遇到一些ora-00704 ora-00604 ora-01555的错误,导致数据库无法正常open,对其进行补充,具体参见:数据库open过程遭遇ORA-1555对应sql语句补充
