Cause:

When the active Connection Group is congested.

Diagnostic Information:

This alarm indicates a routed service is load-balancing traffic across all connections in a connection group, but all of the connections are experiencing congestion. Messages may be discarded due to congestion. Congestion generally occurs when the far-end servers are overloaded.

Overload can be due to following:

• TCP connection has higher latency or error rate, then connection is getting into congestion state
• Far end server is receiving traffic at higher rate (may be from other servers). This triggers ComAgent congestion on far-end side.
• Application process CPU on far-end is above normal.

Recovery:

1. Navigate to Communication Agent > Maintenance > Routed Service Status to view the connection groups and connections associated with the Routed Service.
2. Navigate to Communication Agent > Maintenance > Connection Status to view the are congested and the degree to which they are congested.
3. Check the far-end of the congested connections to further isolate the cause of congestion.

   If the far-end servers are overloaded, then it is possible the system is being presented a load that exceeds its engineered capacity. If this is the case, then either the load must be reduced, or additional capacity must be added.

4. It is recommended to contact My Oracle Support for assistance.
