Automatic Identity Range Management

Hello,
I've got a question dealing with automatic identity range management.
Currently we have a database setup for publication in which the subscribers
are running SQL Server CE on mobile devices. We've got automatic identity
range management turned on for a few of our tables and we're having some
issues with the publisher identity ranges not getting automatically
reassigned after they are exhausted. I found this statement in the SQL Server
manuals:
"If the Publisher exhausts its identity range after an insert, it can
automatically assign a new range if the insert was performed by a member of
the db_owner fixed database role."
The user that is inserting the rows into the publisher database is a member
of the db_owner fixed database role but when a row is inserted which exhausts
the currenty identity range they are not automatically reassigned. I can
manually adjust the identity ranges using sp_adjustpublisheridentityrange
logged in with the same user, but they are not automatically adjusted after
the insert as the documentation suggests.
What else should we check for?
Thanks in advance,
mike...
You have to size the ranges for the max amount of inserts that would occur
between syncs. Otherwise the range will not be adjusted.

|||Hilary, Thanks for the reply - the problem we've run into is that the user
accounts (Windows Auth) sync'ing the devices are not members of the db_owner
role so the merge agents do not refresh the identity ranges (which is another
issues we've been attempting to work around). From our experiences (and from
reading the SQL Server manuals) the publisher identity ranges should refresh
themselves if the inserts are done at the publisher by users in the db_owner
fixed database role. This isn't occuring at one of our sites and I'm
wondering what other security arrangements need to be made for this to occur.
Any ideas?
Thanks again,
mike...
