Multi-user environment

Hi,
I’m working on a project that has MSDE installed on a Server (Windows Small
Business Server 2003 Standard with Veritas Backup V.9.1) for the back-end
database and for the front-end an Access Project (.adp) which I plan to have
on each user's computer.
The Server Administrator is pushing for an update to SBS 2003 Premium with 5
licenses as the only solution. Personally I think MSDE would do the job…
There are few things I’m not so sure:
- How many users can access the server at the same time with MSDE?
- Is there a way to let the user know if a record is being used? Like
displaying a message before any changes are made?
- I’ve created a table for users with username, password and group they
belong to. Is there a way to integrate this with the MSDE Groups and
Permissions or Transact-SQL? So Users, passwords and Groups can be setup from
a form in the front-end.
I’m doing some research on Veritas and see if it would backup the Instance
of MSDE.
Any help on this matter would be greatly appreciated

it's not a matter of users but concurrent batches... a study by Microsoft
indicates a magic number of 25, but it really depends on the application
type/design, database type/design...
of course bad ADO serverside cursors design will be worse then excellent
clientside disconnected design code...
but actually there's no limit, just the buuilt-in Workloads Gevernor that
kicks in when more then 8 concurrent batches are in progress... you can have
a look at

fro further info about that governor...

actually not... you have to test saving and trap the relative exception...

I think you've better drop your user tables and rely on the standard SQL
Server users and roles...you are duplicating all and incurring in troubles..

Thanks so much for your answer. I see I need to change directions in few
settings but I'm on the right track. A lot of information to catch up...

Multiple time stamp values in MSDE

Hi - I am a bit of an amatuer, but I am trying to use the EMS data Pump to get all of the data out of an Interbase 6 DB into an MSDE DB. I have managed to instal an Interbase ODBC driver, and I ca connect to it and then automatically create the tables in my MSDE DB, but I get an error stating that there cannot be multiple Timestamp columns in the MSDE databse. Is this true ?Are you sure you need TIMESTAMP fields? Could it be that you only need multiple DATETIME fields? Besides, the reason you can't have more than 1 true TIMESTAMP field per table is because ... it wouldn't make sense to have more than 1.|||I will look into that. I am just converting an old interbase databse to MSDE so that I can write another app to use its data.

Why whould it mkae no sense to have more than one timestamp field ?

I will try to convert the column to a datetime field. Thanks|||TIMESTAMP is often confused for GETDATE(). The value of TIMESTAMP field is used by the engine as a row version identifier, rather then as a DATE and TIME. It's actually an auto-generated binary number that stays unique within a database, and as per definition has nothing to do with neither date nor time.

Multiple SQL Version

Dear all,
Can I install several version of MSDE in my PC ?
Thanks.You should be able to install multiple instance of MSDE on the same machine.
When you install a new MSDE instance just make sure that it has a different
instance name than already existing ones, else you will encounter an
instance clash error. All common files will be replaced if it detects that
it the one you are installing has a newer version, else it will be left
alone.
