I beg to differ in a point of your post.
If you resize a data file in primary, the standby is not broken.
I am talking of 8.1.5.
I believe resizing of datafile also generates some redo information
that gets passed to standby database. Hence the data file size
of standby also increases automatically.
Adding a datafile is a problem. It stops the recovery process from
happening. You need to *cold* copy the datafile from primary
to standby and add it to your standby database by the command
ALTER DATABASE CREATE DATAFILE '<datafile name>' AS '<datafile name>';
After that, recovery can proceed as normal.
The problem in standby is as you pointed out the unrecoverable
activities. If any so-called poweruser performs that,
your standby database is broken.
Thanks and Great Regards,
