Advantage Error Guide
Problem: An open table greater than 4GB in size was attempted with compatibility locking. Due to lock offsets required to implement record locking that can be shared across applications (either non-Advantage applications or applications that use Advantage Local Server), the table cannot be opened.
Solution: If you are using Advantage Database Server, open the table with proprietary locking. With Advantage Local Server, it is necessary to open the table in exclusive mode.
