A POM system might need a restart when any component such as the application server, MPP, or EPM becomes non functional ungracefully such as in case of network outage, power outage, or database connectivity issues. All components are essential for nailing calls for agent-based campaigns. The POM system might be connected to some external components such as Avaya Aura® System Manager or Avaya Experience Platform™ (AXP) On-Prem (formerly Avaya Call Center Elite). In such cases, to make the POM system functional, you must restart the components in the order specified in the proposed solution.
