3.7.12 19808 - Communication Agent Connection FIFO Queue utilization

Alarm Group:
CAF
Description:
The percent utilization of the Communication Agent Connection FIFO queue is approaching defined threshold capacity. If this problem persists and the queue reaches above the defined threshold utilization, the new ComAgent internal Connection Management StackEvents messages can be discarded based on Application's Global Congestion Threshold Enforcement Mode.
Severity:
Minor, Major, Critical
Instance:
<ComAgent StackTask Name>
HA Score:
Normal
Auto Clear Seconds:
0 (zero)
OID:
cAFMxFIFOUtilNotify
Cause:
Minor (>= 60%), Major (>=80% ), Critical (>=95%), Percentage level of Max = 1000
Diagnostic Information:
The percent utilization of the Communication Agent Connection FIFO queue is approaching its defined capacity. If this problem persists and the queue reaches above the defined threshold utilization, the new ComAgent internal Connection Management StackEvents messages can be discarded based on Application's Global Congestion Threshold Enforcement Mode. This alarm should not normally occur when no other congestion alarms are asserted.

Recovery:

  1. Use Main Menu, and then Alarms & Events to determine if the ComAgent worker thread may be experiencing a problem preventing it from processing events from ComAgent Connection FIFO queue.

    It is recommended to contact My Oracle Supportfor assistance.

  2. An IP network or adjacent node problem may exist preventing transmission of messages into the network at the same pace the messages are being received from the network.
  3. Navigate to Status & Manage, and then KPIs to monitor the ingress traffic rate of each MP.
    • The mis-configuration of adjacent node IP routing may result in too much traffic being distributed to the MP. Each MP in the server site should be receiving approximately the same ingress transaction per second.
    • There may be an insufficient number of MPs configured to handle the network traffic load. If all MPs are in a congestion state then the offered load to the server site is exceeding its capacity.
  4. If the problem persists, it is recommended to contact My Oracle Support for assistance.
