To configure high availability successfully, each step must be performed in order as they appear in this section. After each step, a use-case example to demonstrate the configuration process is provided. The following figure and table describe the terms used during the failover configuration process.


Example Server Name Server Type Description
DM1 Original-active The system primarily used as the active system before failover occurred. Typically, the server where the primary Data Mover ActiveMQ daemon, agent, and REST reside.
DM2 Designated-standby The standby system assigned to take responsibility as the active system if the original-active stops working. If the DM1 server fails, this is the server that becomes the next active. In the meantime, one Data Mover agent runs here.
DM3 Additional agent Server where one Data Mover agent runs. Not a standby server.
VP1 Orignal-active monitor Server where the primary Data Mover monitor runs. This monitor continuously checks that DM1 is running properly and initiates failover to DM2 if necessary.
VP2 Designated-standby monitor Server where the secondary Data Mover monitor runs. This monitor only becomes active if failover occurs. If failover occurs, this monitor continuously checks that DM2 is running properly and initiates failover to DM1 if necessary.
