ACC: "File Already in Use" Error When Opening Database on Novell

View products that this article applies to.


When you try to open a database that is located on a Novell NetWare server, you may receive the following error message:
Couldn't use <filename>; file already in use.

If a user opens a database and doesn't have Create rights for the folder in which the database is located, the Microsoft Jet database engine can't create the locking information file (*.ldb) that is necessary for multiple users to open the database. Therefore, a user who doesn't have Create rights opens the database exclusively if a corresponding .ldb file does not already exist.

To prevent this behavior, make sure that all users who open the database have read, write, create, and delete rights for the folder in which the database is located.

More information

In order to open a database in shared mode, the Microsoft Jet database engine must be able to create a locking information file (*.ldb) in the same folder as the database itself.
