Shared database

Ramesh - 21 May 2007 09:54 GMT
Hi,

I have a database file (MDB) on my assistant s PC.  When I open this file in
Access in that PC, i am unable to open the same file on my PC.  (2 PCs on
peer to peer)  If I open the same file from  my PC first, then it opens fine
on her PC too.  On both PCs it is set to open in Shared mode.  In both
cases, the .LDB file is created on opening.

Where could the problem be?  Every time i need to use the file, i am having
to ask her to close the db, till i open it for my use.  Once i open it, then
she re opens to continue her work.

Could anyone help me save this pain please?

Thanks
Ramesh

   I don't have an answer to your specific problem, but I would offer a
couple of general observations.

 1. Access does not like marginal networks and peer to peer is usually
marginal.
 2. Shared databases are almost always happier if they are split with a
front end linked to the "back end" database rather than sharing the same
database.

stop blaming everything on the network, dipshit!

it's not the networks fault-- it is Access MDB

Access works great across all networks, ADP works great over VPN,
Wireless and WAN

Access MDB is for cripples and retards--
Access MDB should only be used by homeless people

What Aaron posted MEANS NOTHING. It's just disinformation, designed
to provoke the regulars in the newsgroup.

Ignore it.

It is not helpful information at all.

   Aaron, why do you keep posting under different names.  Everyone really
knows who you are.

Sorry about Aaron - you get all types in a public forum!!

This sounds like a permissions problem.

This is probably a permissions problem on the directory in which the backend is
installed.   The users must have create/delete privileges to that directory.  What is
happening is that Access can't create the .ldb file which allows multiple users to
update the MDB.  So Access only allows one user at a time.

One simple way of testing this is to ensure the users can create and delete a file in
the network share.   Any file, even using notepad, is enough to test this. I simply
don't trust all those permissions screen within the OS.  You never quite know whats
lurking behind the advanced button.  So test this yourself.

Sometimes it could only be one user who does not have create privileges to cause
problems who just happens to be the first user into the MDB at that moment in time.
Then all the other Access users can't access the file because the first user is in
exclusively.

"I found that I could keep the permissions set to Change, but had to ensure that the
directory in which the db resides was set to not inherit permissions from it's
parent.  It seemed that every time a new user logged onto a given machine, it got
messed up."

See ACC: Determining Which User Has Opened Database Exclusively (Q169648)
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q169648
Essentially you must use tools on the server to determine who has locked the file.

For MS info see ACC: Introduction to .ldb Files (95/97) [Q136128].  Or the version
appropriate for your version of Access.'

sounds to me like you haven't analyzed your database needs

Access MDB is a file-based database

if you care enough about your data to make a database; you really should
consider using a database SERVER such as MSDE or SQL Server

Everyone please note that Aaron  Kem.pf is attempting to impersonate one of
our regular posters again.  Tom would never post such a message.

HTH.

sounds to me like a reliability problem

if your database craps out then find a real database
