On a regularly scheduled basis, I do a journal switch & save the replaced
journal receiver.  Until recently, when I did the save I was FREE'ing the
storage used by the receiver.  There were many times when I could not do
the FREE because the just replaced receiver contained journal entries which
had not been committed or rolled back.  No problem, I did another save 1/2
hour later to catch any receivers which had not been FREED.

My question is, if the just saved receiver contains entries which are
subsequently rolled back, is the saved receiver still valid for recovery
purposes?  ie Will the system recognize the fact that an entry has been
rolled back?  Is there an entry in the new receiver indicating that such
and such a commit boundary has been rolled back or does the system just
remove the entries from the old receiver.  If the latter, it seems to me
that the saved receiver is no longer valid for recovery purposes.

I hope this made sense.

Gord
