Actually, nice suggestion. In 8i (and probably earlier) no check was
made on controlfile size (in the file header against fs) when
mounting/opening the database. One of our customers had a problem then
with the standby database - he incorrectly transfered cf to standby site
(something like dd if=...| rsh 'dd of= '). I.e. standard error of local
dd was written somewhere at the end. Problem showed only on cf extend on
standby. One thing that helped during investigation - the resulting file
size was an ODD number of bytes :-).
Fixed in 9i. Not checked in 10g.
