出现该错误的原因是由于：We are attempting to write a controlfile checkpoint progress record, but find we do not have the progress record generating this exception.由于控制文件异常导致,出现此类情况,我们一般使用单个控制文件一次尝试,如果都不可以考虑重建控制文件
由于坏块(逻辑/物理)导致数据库实例恢复无法进行

查看资料发现和Bug 14301592 – Several errors by corrupt blocks shifted by 2 bytes in buffer cache during recovery caused by INDEX redo apply，可以通过ALLOW 1 CORRUPTION临时解决
使用ALLOW 1 CORRUPTION进行恢复,出现ORA-07445[kdxlin]错误

ORA-07445[kdxlin()+4088]未找到类似说明,到了这一步,无法简单的恢复成功,只能通过设置隐含参数跳过实例恢复,尝试resetlog库
通过设置_allow_resetlogs_corruption参数继续恢复

这里是比较熟悉的ora-600[kclchkblk_4]错误,和ora-600[2662]错误类似,需要调整scn,由于数据库版本为11.2.0.4,无法使用常规方法调整scn,在修改控制文件,oradebug,bbed方法可供选择
使用oradebug方法处理
因为是asm环境,其他方法处理起来都相对麻烦

至此数据库open成功,后续就是处理一些坏块的工作,并建议客户逻辑重建库.
