I am trying out this hidden utility and i can recover deleted rows and modify data blocks, but i am not understanding how the recover block option is working .
In Graham Thornton guide page 31 it says quote "
The sequence number also comprises one component of the tailcheck of the block, which occupies the last 8 bytes. This also needs to be reset for Oracle to recognize the block as valid again.
Using bbed we can print the tail check and see that is 0x000006ff , However when we reset it we must remember that this value is interpreted as a single unsigned integer. On Intel machines therefore, the value is stored low-order byte first.
BBED> p tailchk
ub4 tailchk @8188 0x000006ff
BBED> moidfy /x 0106000 dba 7,16 offset 8188
"
my question is : why/how the value of 0106000 is being used as the modificaion value?
thanks
