kccpb_sanity_check_2内核函数kernel function负责监测控制文件的健康性，该ORA-600[kccpb_sanity_check_2]一般在alter database mount阶段发生；该ORA-600[kccpb_sanity_check_2]发生的原因一般是控制文件controlfile 块头的seq#号大于控制文件头中的seq#，所以该监测函数认为存在控制文件逻辑不一致。

该kccpb_sanity_check_2函数是从10gR2才引入了，换句话说9i没有这样的控制文件健康性监测，引入该特性的目的是为了检测出写丢失lost write和陈旧读stale read。

该ORA-600[kccpb_sanity_check_2]一般有2个argument代码:

ARGUMENTS:
Arg [a] seq# in control block header.
Arg [b] seq# in the control file header.
Arg [c] maclean

ksedmp: internal or fatal error
ORA-00600: internal error code, arguments: [kccpb_sanity_check_2], [53672], [53643], [0x000000000], [], [], [], []

上例是一个ORA-600[kccpb_sanity_check_2]的实战案例，虽然出现了该错误，但是由于多路复用了controlfile控制文件，通过修改参数control_files ，发现其中第二个控制文件mount时未报错，可以确信仅有1个控制文件有问题，所以只需要dd 复制一下即可。

针对这个实例mount阶段的ORA-600[kccpb_sanity_check_2]错误，一般有几种解决方法：

1、如果多路复用了控制文件，则未必所有控制文件都坏了，修改control_files参数一个个试过来，注意当好的控制文件和坏的控制文件都在参数control_files里时是无法mount成功的
