int
DB_ENV->repmgr_set_local_site(DB_ENV *env,
    const char *host, u_int port, u_int32_t flags);  

The DB_ENV->repmgr_set_local_site() method specifies the host identification string and port number for the local system.

The DB_ENV->repmgr_set_local_site() method may not be called after the DB_ENV->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 DB_ENV->repmgr_set_local_site() method returns a non-zero error value on failure and 0 on success.
