My customer will install two separate MDBs (identical structure) in two sites. Each user will access and update their local MDBs. The customer requires to have 2 MDB synchronization automatically. Does MDB replicate work fine? But it seems that MDB replication requires all the users log out from the MDB before the synchronization process. The customer must require to do synchronization automatically where the users are still using the local MDB. Please advise me. Thanks
