int
DbEnv::rep_set_nsites(u_int32_t nsites); 

The DbEnv::rep_set_nsites() method specifies the total number of sites in a replication group.

The DbEnv::rep_set_nsites() method is typically called by Replication Manager applications. (However, see also the DbEnv::rep_elect() method nsites parameter.)

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_nsites", one or more whitespace characters, and the number of sites specified. For example, "rep_set_nsites 5" sets the number of sites to 5. Because the DB_CONFIG file is read when the database environment is opened, it will silently overrule configuration done before that time.

The DbEnv::rep_set_nsites() method configures a database environment, not only operations performed using the specified DbEnv handle.

If master leases are in use, the DbEnv::rep_set_nsites() method may not be called after the DbEnv::rep_start() or DbEnv::repmgr_start() methods are called. If master leases are not in use, the DbEnv::rep_set_nsites() method may be called at any time during the life of the application.

The DbEnv::rep_set_nsites() 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.
