Synchronization via TCP/IP

You can synchronize the remote database with the consolidated database using a TCP/IP socket connection. Call ULSynchronize with the ULSocketStream() stream.

auto ul_synch_info synch_info;
ULInitSynchInfo( &synch_info );
synch_info.user_name = UL_TEXT("50");
synch_info.version = UL_TEXT("custdb");
synch_info.stream = ULSocketStream();
synch_info.stream_parms = 
   UL_TEXT("host=localhost;port=2439");
ULSynchronize( &sqlca, &synch_info );

In order to synchronize with the CustDB consolidated database, the employee ID must be supplied. This ID identifies an instance of an application to the MobiLink server. You may choose a value of 50, 51, 52, or 53. The MobiLink server uses this value to determine the download content, to record the synchronization state, and to recover from interruptions during synchronization.
