这个错误处理有多次处理经验
12c启动报kcratr_nab_less_than_odr
又一例ORA-600 kcratr_nab_less_than_odr
ORA-600 kcratr_nab_less_than_odr故障解决
差点被误操作的ORA-600 kcratr_nab_less_than_odr故障
11.2.0.4库中遇到ORA-600 kcratr_nab_less_than_odr报错
ORA-600 kcratr_nab_less_than_odr和ORA-600 4194故障处理
一般重建ctl或者using backup ctl方式恢复即可实现0丢失打开库,但是这个库尝试打开报ORA-600 2662错误

对于这样的ORA-600 2662错误是比较常见的问题,直接通过Patch_SCN工具修改scn即可正常打开库

*********************************************************************
WARNING: The following temporary tablespaces contain no files.
         This condition can occur when a backup controlfile has
         been restored.  It may be necessary to add files to these
         tablespaces.  That can be done using the SQL statement:
 
         ALTER TABLESPACE <tablespace_name> ADD TEMPFILE
 
         Alternatively, if these temporary tablespaces are no longer
         needed, then they can be dropped.
