oracle数据库数据丢失的恢复过程(12tb数据)

时间:2016-04-25 00:00:00 编辑:简简单单 来源:转载

本来是一件很简单的事情,restore文件,然后recover归档,恢复到某个点,然后open resetlogs 打开数据库,但是居然报错,ora-600 [4097],很常见的一个错误,不过比较怪异的是,这里并没有直接提示是哪个回滚段有问题,如下是trace内容:


ksedmp: internal or fatal error

其实大家可以尝试reset incarnation,然后再去restore归档,然后recover,想想麻烦,反正是测试,所以继续搞下去。

首先利用10046 event 来跟踪一下,发现如下sql报错:


PARSING IN CURSOR #2 len=148 dep=1 uid=0 oct=6 lid=0 tim=11525224803938 hv=3540833987 ad='9f8d140'

  kxsbbbfp=70000050bfe3922  bln=32  avl=10  flg=09
  value="_SYSSMU29$"
 Bind#1
实际上因为oracle 在open的时候会去判断回滚端上是否存在事物,如果存在,那么就会进行update,如果进行update那么也就说明正在open的时候需要更新回滚端的信息。这里尝试使用参数将上述几个回滚端屏蔽掉,发现仍然无法open,再次寻找10046 trace,发现原来是另外一个回滚段可能有问题,如下:

  value="_SYSSMU61$"

果断再次屏蔽,然后尝试open resetlogs,发热仍然报错,原来这个回滚端用无法直接offline,隐含参数不好用,因此直接bbed 修改状态吧,如下:

修改之后成功open 数据库。

虽然打开了,但是奇葩的还在后面,当我shutdown 再次启动,居然无法启动了。 报错ora-01555,比较经典的错误。

比较郁闷的是system 回滚段。很明显这也跟scn有关系,aix平台,尝试oradebug 修改scn,发现比较费劲。
最后果断bbed 再次修改block(仍然通过10046 trace 寻找相关的block).
