Example 1 with MasterFactory

use of org.apache.derby.iapi.store.replication.master.MasterFactory in project derby by apache.

the class RawStore method startReplicationMaster.

 * Start the replication master role for this database
 * @param dbmaster The master database that is being replicated.
 * @param host The hostname for the slave
 * @param port The port the slave is listening on
 * @param replicationMode The type of replication contract.
 * Currently only asynchronous replication is supported, but
 * 1-safe/2-safe/very-safe modes may be added later.
 * @exception StandardException 1) If replication is started on a read-only
