分享一次由于一个表异常导致数据库报类似：ORACLE Instance XFF (pid = 18) – Error 600 encountered while recovering transaction故障的案例
一个10.2.0.4的数据库,正常运行的库突然出现如下错误

过一段时间报，然后实例直接crash

根据以上报错，数据库crash的原因是由于undo异常导致，通过对undo进行重建，解决掉异常undo，但是业务运行之后，一样的问题又重现，最后通过分析确认是对象异常导致

SQL> create table XFF.T_XIFENFEI_xff as select * from XFF.T_XIFENFEI;
create table XFF.T_XIFENFEI_xff as select * from XFF.T_XIFENFEI
                                                           *
ERROR at line 1:
ORA-00600: internal error code, arguments: [kcbz_check_objd_typ], [0], [0], [1], [], [], [], []

屏蔽相关block obj的check之后
SQL> create table XFF.T_XIFENFEI_xff as select * from XFF.T_XIFENFEI;
create table XFF.T_XIFENFEI_xff as select * from XFF.T_XIFENFEI
                                                           *
ERROR at line 1:
ORA-00600: internal error code, arguments: [ktspScanInit-l1], [], [], [], [],[], [], []

比较明显该表对象出现逻辑异常，通过基于rowid的方式对该表数据进行抽取

SQL> create table XFF.T_XIFENFEI_new
  2  as
  3  select * from XFF.T_XIFENFEI where 1=0;

Table created.

再次观察数据库恢复正常,也不再crash和报错,恢复完成
