Heiko, you must not have the latest book, SG24-4335-02....it has alot
of details about what happens to the data stored on the ADSM server...
in fact, it is a crucial consideration with onbar....onbar works differently
than the other api applications.  Onbar does reuse object names so you do
end up with multiple versions on the ADSM server.  All the other api appls
use unique object names ever time they send a backup.  Also, onbar does
not issue the delete object api call, which is how objects are supposed to
be deleted on the adsm server....therefore, the way they are deleted is just
with normal adsm versioning and file expiration processing.  This means that
stuff can get deleted from the ADSM server, but the onbar catalogs don't know
that it has....we have a lot of write up about this in the redbook....the
best suggestion for now is to keep lots of versions on ADSM.  Informix is
aware of this and plans to change the implementation in a future release.
We also document in the redbook a way to try and live with this until them...
a rather crude, but workable process.
