#include <db_cxx.h> int repmgr_set_local_site(const char * host, u_int16_t port, u_int32_t flags);
         The DbEnv::repmgr_set_local_site() method specifies the host
         identification string and port number for the local system.
    
         The DbEnv::repmgr_set_local_site() method may not be called after
         the DbEnv::repmgr_start() 
         method is called.
    
The database environment's replication subsystem may also be configured using the environment's DB_CONFIG file. The syntax of the entry in that file is a single line with the string "repmgr_set_local_site", one or more whitespace characters, and the host and port parameters specified as a string and an integer respectively. For example, "repmgr_set_local_site example.com 49200". Because the DB_CONFIG file is read when the database environment is opened, it will silently overrule configuration done before that time.
         The DbEnv::repmgr_set_local_site() 
            
            
                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
