The Data Center (DC) failover is a manual process and the administrator must activate POM systems in another DC to start outbound dialing. POM systems are deployed in hot standby state, so they become operational instantaneously and can start dialing (assuming agents are ready and nailed again). On DC failover, agents must log out from the client and log in using POM system from DC2.

After the failover, the campaigns might not finish automatically because the contacts which were in progress when the failover occurred might not finish. Or, might have inconsistent state in database causing campaigns to get stuck. The administrator has to stop those campaigns from web console after all the records are dialed. Such contacts will have completion code marked as DESKTOP_ERROR and can be identified from reports and attempted by using a separate campaign in POM.

POM dialing is impacted when database is accessed over WAN. To access the database locally rather than over WAN, the administrator must ensure the following:

• In the event of a database failover, the POM system is moved to standby state explicitly from the GUI.

• Activate another POM system in DC where the database is currently active.
