22055 - Non-Preferred Route Group in Use

Alarm Group:
DIAM
Description:
The application has started to utilize a Route Group other than the highest priority Route Group to route Request messages for a Route List because the highest priority Route Group specified for that Route List has either become Unavailable or its capacity has dropped below the minimum capacity configured for the Route List while a lower priority Route Group has more capacity.
The preferred Route Group (i.e., with highest priority) is demoted from the Active Route Group to a Standby Route Group when a peer failure occurs causing the Route Group's Operational Status to change to Unavailable or Degraded. A Route Group becomes Degraded when its capacity has dropped below Route List's configured minimum capacity. A Route Group becomes Unavailable when all of its peers have an Operational Status of Unavailable or Degraded.
A Peer becomes Unavailable when all of its transport connections become Unavailable. If a Transport Connection is configured for Initiate mode, the Network Element will periodically attempt to automatically recover the connection if its Admin State is Enabled. If the Transport Connection is configured for Responder-Only mode, the peer will be responsible for re-establishing the transport connection.

Recovery:

  1. Route List status and configured minimum capacity can be monitored from Diameter > Maintenance > Route Lists.
  2. Verify that IP network connectivity exists between the MP server and the peers.
  3. Check the event history logs for additional DIAM events or alarms from this MP server.
  4. Verify that the adjacent server is not under maintenance.
  5. If the problem persists, it is recommended to contact My Oracle Support.
