Cause

This alarm raises when the Average Policy and Charging ingress messages rate exceeds the configured threshold. The thresholds are based on the engineered system value for Ingress Message Capacity.

Diagnostic Information:

The alarm thresholds for DSR Application Ingress Message Rate are configured network wide on Network OAM using the Policy DRA > Configuration > Alarm Settings and Congestion Options screens.
Monitor the ingress traffic rate of each MP by selecting Main Menu > Status & Manage > KPIs. If MPs are in a congestion state, then the offered load to the server site is exceeding its capacity.

Recovery:

Adjust the alarm threshold parameters. Verify the configuration by navigating to the Congestion Options on Policy DRA > Configuration > Alarm Settings.
There may be an insufficient number of MPs configured to handle the network load. Monitor the ingress traffic rate of each MP by selecting Status & Manage > KPIs.
If MPs are in a congestion state, then the offered load to the server site is exceeding its capacity.
If the problem persists, it is recommended to contact My Oracle Support.
