#include <db_cxx.h> int DbEnv::rep_sync(u_int32_t flags);
         The DbEnv::rep_sync() method forces master synchronization to begin
         for this client.  This method is the other half of setting the 
         DB_REP_CONF_DELAYCLIENT 
         flag via the DbEnv::rep_set_config() 
         method.
    
         If an application has configured delayed master synchronization, the
         application must synchronize explicitly (otherwise the client will
         remain out-of-date and will ignore all database changes forwarded from
         the replication group master).  The DbEnv::rep_sync() method may be
         called any time after the client application learns that the new
         master has been established (by receiving a 
         DB_EVENT_REP_NEWMASTER 
         event notification).
    
Before calling this method, the enclosing database environment must already have been opened by calling the DbEnv::open() method and must already have been configured to send replication messages by calling the DbEnv::rep_set_transport() method.
         The DbEnv::rep_sync() 
            
            
                method either returns a non-zero error value or throws an
                exception that encapsulates a non-zero error value on
                failure, and returns 0 on success.

                method may fail and throw a DbException 
                exception, encapsulating one of the following non-zero errors, or return one
                of the following non-zero errors:
            
        
         
If the database environment was not already configured to communicate with a replication group by a call to DbEnv::rep_set_transport(); the database environment was not already opened; or if an invalid flag value or parameter was specified.
