Chantal, informix onbar has not yet been updated to use unique object names
and to issue delete api calls to storage management vendors.  As far as
I know, they do not have any updates planned in the near future, although
my past conversations with the onbar designer led me to believe that they
understand that this is something that should be changed in the future.

So, the redbook instructions are still valid about ways to try and avoid
inconsistencies between onbar's backup catalog and ADSM's database.
