Field Detail

REP_CLIENT

public static final ReplicationManagerStartPolicy REP_CLIENT

Start as a client site, and do not call for an election.

REP_ELECTION

public static final ReplicationManagerStartPolicy REP_ELECTION

Start as a client, and call for an election if no master is found.

REP_FULL_ELECTION

public static final ReplicationManagerStartPolicy REP_FULL_ELECTION

Start as a client, and call for an election if no master is found.

The DB_REP_FULL_ELECTION flag configures a single special election on startup, where a master will only be confirmed if all members of the replication group vote. Subsequent elections will revert to only requiring a simple majority to elect a new master.

REP_MASTER

public static final ReplicationManagerStartPolicy REP_MASTER

Start as a master site, and do not call for an election. Note there must never be more than a single master in any replication group, and only one site should ever be started with the DB_REP_MASTER flag specified.
