DB Locking

[Simon Stockdale]

Hi,

I have an application framework which consists of several
webservices, webpages and application all of which use a
couple of MS Access database. We are currently in the
testing phase of the project so we don't want to have to
upgrade to SQL Server yet.

The problem is that when the webservices or applications
open the connections to the databases they open it in
single user mode. No matter what connection strings I use
they still refuse to open in multi-user mode.

This is the connection string I'm using:

"Provider=Microsoft.Jet.OLEDB.4.0;Password='';User
ID=Admin;Data
Source=E:\BORG\TypeProcessor\TypeProcessor.mdb;Mode=Share
Deny None;Jet OLEDB:System database='';Jet OLEDB:Registry
Path='';Jet OLEDBatabase Password='';Jet OLEDB:Engine
Type=5;Jet OLEDBatabase Locking Mode=1;Jet OLEDB:Global
Partial Bulk Ops=2;Jet OLEDB:Global Bulk
Transactions=1;Jet OLEDB:New Database Password='';Jet
OLEDB:Create System Database=False;Jet OLEDB:Encrypt
Database=False;Jet OLEDBon't Copy Locale on
Compact=False;Jet OLEDB:Compact Without Replica
Repair=False;Jet OLEDB:SFP=False"

Can you suggest anything?

Thanks,

Simon Stockdale

Hi Simon,

I could not reproduce it using the connection string you provided. By
default, the OleDbConnection opens a .mdb database in multi-user mode if
you didn't specify to open it exclusively. You can try to see if there is a
file named TypeProcessor.ldb in the same folder as TypeProcessor.mdb. If
yes, delete it. The former user might opened the file in single-user mode
and didn't exit properly. So the file might not be opened by multi-user.

If anything is unclear, please feel free to reply to the post.
