How can I best synchronize a Notes DB and MS Access data? I would like to synchronize only in the morning in one direction and in the evening in the other. Could you help me please?
Lotus Enterprise Integrator (LEI) -- read about it here. Create two replication activities -- one to migrate data from Access (using the ODBC or OLE DB connector) to Notes, and one to go the other way. Schedule them to run daily at the appropriate times. Use Order metaconnectors on both sides to make sure the Notes data are sorted (this shouldn't be necessary but apparently is in current versions; we're investigating).
You could of course program the same operation using the LC LSX and make it a couple of scheduled agents. LEI just makes it easier. Refer to What's wrong with my code?? for a description of the basic replication algorithm.
