Chapter 6 Cisco Unified Serviceability Alarms and CiscoLog Messages
Error-Level Alarms
Cisco Unified Communications Manager (Unified CM) received a 4xx or 5xx response from the policy
decision point (PDP). A 4xx response indicates errors in the call routing request from Unified CM, for
example: a 400 response indicates the call routing request could not be understood by the PDP; a 404
indicates that the PDP did not find a matching request URI. A 5xx error indicates a PDP server error, for
example: a 500 response indicates a PDP internal error; A 501 response indicates that the PDP does not
support the functionality to generate a call routing response; a 503 indicates that the PDP is busy and
temporarily cannot generate a response; a 505 indicates that the HTTP version number included in the
call routing request from Unified CM is not supported. Other such errors may be responsible; please
refer to generally available guidelines on HTTP or check the RFC 2616 for detailed explanations about
HTTP Status Code definitions.

Recommended Action
If a 4xx response caused the alarm, verify that the PDP has been accurately configured for the
functionality and call routing that you expect it to perform. If a 500 response causes the alarm, check
whether the PDP service is active and check the PDP server's log files for any errors. If a 503 causes the
alarm, the PDP may be overloaded by requests. Take appropriate action to reduce the load on the PDP
by following some or all of these recommendations: 1) consider adding more PDPs and provisioning
Unified CM with additional call intercept profiles and call intercept trigger points in the various
configuration pages under the Call Routing menu in Cisco Unified CM Administration; 2) provision a
pair of policy servers per call-intercept profile to enable load balancing; or 3) verify that the PDP server
in your deployment meets or exceed the hardware requirements specified in the documentation for Cisco
Enterprise Policy Manager (CEPM) or the third-party PDP solution you have deployed. If a 505 response
causes the alarm, check to be sure that the PDP supports HTTP version 1.1.
ReadConfigurationUnknownException
An exception is caught while retrieving enterprise parameters value from database at TFTP service
startup. This is usually caused by a failure to access the Cisco Unified Communications Manager
database.
