You may or may not be able to identify the machine. Until that lock is released, you're locked out. Note that row-locking queries, page-locking queries, and table-locking queries are functionally identical for the issue that matters to you: if you need to do something (like compact and repair) at the 'file' level, the file is locked against you. If you're lucky, the connection object is configured correctly, so the machine ID is in the connection string, ensuring it'll turn up in the locking file and allow you to locate the machine with the lock. Worse, some third-party systems may well need to write data: this should be avoided - go through the Access client application! - but you don't always get to make that decision. Bored Excel users watching a slow pivot 'refresh' do this all the time. If their connections are badly configured, they can lock your table while retrieving: and terminating the client session can leave the lock in place. Some reporting apps - and Excel Pivot Tables - may link to your db, and the owners simply don't tell you.

Some reporting apps, like QLikView, are opaque interfaces that demand the full filename and nobody knows what happens next: maybe it locks, maybe it doesn't. If you're lucky, the system owners use a dsn file you control, and you can see that setting. Third-party reporting applications using ODBC or ADO to your Access database should have their connections set read-only, so that they can't lock the file.
You can trace those using the lock file (.ldb or. Forced restarts of the offending machines should release the lock, and mostly will.
The last two items in that list are rare - it takes some effort to affect another database file outside the one you've opened in your session, but it is sometimes observed in the wild - but closing those sessions should release the lock and almost always will.Ĭrashed MS-Access sessions can keep a file lock on the. mdb back-end database file if they edit data, change an object (eg: index a table) or perform a maintenance task. Live MS-Access sessions can keep a file lock on the.
The locking file is a useful tool but it's an indicator, not the actual lock: you can edit it but that has no effect. However, it's not convenient, and it's not simple to implement.įirst, some background on locking files and the locked file. Select the file you wish to unlock, and delete the session.Ī fix exists, and I have it in place for an MS-Access Application I maintain. Alternatively: Admin tools, Computer Management,System Tools,Shared Folders, Sessions. So if you turn off a PC, wait 15 minutes, then the Windows/Network locks will go (default timing).

Last I looked, Windows Server was set by default to time-out broken file connections 15 minutes after the network session was lost. Access is not a network administration program that does this for you. You need to go to the Server/PC that hosts the file, and force the disconnection. If ANY Windows/Network locks exist, nothing you do with Access can allow you to disconnect another person from the network. If ONLY the Access/LDB "locks" exist, you can delete the LDB, and then get exclusive ownership. If EITHER the Windows locks or the Access/LDB "locks" exist, you can't get exclusive ownership. Since Access is ignoring existing "lock" entries to clear broken "lock" entries, this is how Access/Windows prevents Access deleting the LDB while another user is still using it. You get rid of them by deleting the LDB.Īccess won't be able to delete the LDB if a user still has Windows/Network locks on the LDB.

If Access crashes, or the network is disconnected, or the PC or Server is turned off, the LDB will have data ("locks") that have not been deleted. That is why Access always attempts to delete the LDB on close. To 100% bulletproof empty the LDB, you delete the LDB. MSAccess won't let you exclusive lock while the LDB has entries showing someone else is using the database, and Windows won't give you an exclusive lock while it has locks showing someone else is using the database. To get exclusive locking on an MDB, you need both. If there are no locks ON the mdb, the user is not using that Windows/Networking service. If there are no locks IN the ldb, the user is not writing into the MDB. These locks are part of the native database primitives provided by Windows and Windows networking. Users also put "locks" onto LDB's and MDB's. An LDB is a kind of database of locks for MS Access.
