ORA-00600: [kccpb_sanity_check_2] During Instance Startup [ID 435436.1]

Cause

ORA-600 [kccpb_sanity_check_2] indicates that the seq# of the last read block is

higher than the seq# of the control file header block. This is indication of

the lost write of the header block during commit of the previous cf

transaction.

kccpb_sanity_check_2 表示最后读取的控制文件块其 seq# 控制序列号大于控制文件头块的 seq# ,这是不应该出现的情况。这说明在最后执行提交的控制文件事务（CF Transaction）中，对于头块的写入丢失了

Solution

1) restore a backup of a controlfile and recover

OR

2) recreate the controlfile

OR

3) restore the database from last good backup and recover

NOTE:  If you do not have any special backup of control file to restore and you are using Multiple Control File copies in your pfile/init.ora/spfile you can attempt to mount the database using each control file one by one.  If you are able to mount the database with any of these control file copies you can then issue 'alter database backup controlfile to trace' to recreate controlfile.
