How would i do that...Do i do a startup mount and say recover database until
cancel and start applying archive logs generated between T1 and T2 with or
without cataloging in control file ??..Technically there is nothing to
recover isn't it. It is an instance recovery situation.
In that situation can we mount and say recover database until cancel and
apply additional archive logs ??
Thanks
