#include <db_cxx.h> int DbEnv::rep_set_priority(u_int32_t priority);
         The DbEnv::rep_set_priority() method specifies the database
         environment's priority in replication group elections.  A special
         value of 0 indicates that this environment cannot be a replication
         group master.
    
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 "rep_set_priority", one or more whitespace characters, and the priority of this site. For example, "rep_set_priority 1" sets the priority of this site to 1. Because the DB_CONFIG file is read when the database environment is opened, it will silently overrule configuration done before that time.
Note that if the application never explicitly sets a priority, then a default value of 100 is used.
         The DbEnv::rep_set_priority() method configures a database
         environment, not only operations performed using the specified 
         DbEnv  handle.
    
         The DbEnv::rep_set_priority() method may be called at any time
         during the life of the application.
    
         The DbEnv::rep_set_priority() 
            
            
                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.
            
        
    
The priority of this database environment in the replication group. The priority must be a non-zero integer, or 0 if this environment cannot be a replication group master. (See Replication environment priorities for more information).
