Prem,
You seem to forget the case where the standby could have inferior hardware, for
example slower storage, fewer CPUs, etc., and in case of active data guard,
expensive queries. According to my test
http://www.freelists.org/post/oracle-l/Why-extra-standby-redo-log-group,8
it *is* possible that the extra SRL becomes active.
But I think it's only best practice, not requirement.
