Symptoms

While testing High Availability (HA) scenarios in Elastic Charging Engine (ECE) Patch Set 9 Interim Patch 3, in below scenario it was noted that Rated Event Formatter (REF) is losing the rated events when there is a network failure.

Scenario 1: Not working

  1. ECE is in HA servers.
  2. Rated Event Formatter (REF) is running in HA mode.
  3. Start processing some online usage.
  4. Check the Elastic Charging Server (ECS) nodes where the rating is happening. REF should be running in the same node.
  5. Stop only the network interface in that VM (virtual machine).
  6. Startup the network interface. All the members join back to the cluster.
  7. Rated Event Formatter will start processing the rated events from NoSQL.
  8. Count the number of usage requests processed by the online usage.
  9. Count the number of rated events loaded in Billing and Revenue Management (BRM). There are some missing rated events in (BRM).

Scenario 2: Working

  1. ECE is in HA servers.
  2. REF is stopped.
  3. Start processing some online usage.
  4. Check the ECS nodes where the rating is happening.
  5. Stop only the network interface in that VM.
  6. Startup the network interface. All the members join back to the cluster.
  7. Count the number of usage requests processed by the online usage.
  8. Count the number of rated events in NoSQL database. This matches perfectly.
  9. Started REF and found that all the rated events are successfully processed in BRM.
