Opportunistic locking is a mechanism for client/server databases to allow multiple processes to lock the same file while allowing for local (client) data caching to improve performance over Windows networks.

Unfortunately, the default setting of the opportunistic locking mechanism that enhances the performance of one type of database also introduces data integrity issues for other database types. We have observed numerous instances where opportunistic locking does not release locks correctly, causing performance and data integrity issues.

Since disabling opportunistic locking involves editing the registry, contact your qualified IT professional for assistance.
