[cisco-voip] Informacast SNMP error with UCM

[Wes Sisk (wsisk)]

Looks like the ultimate root cause for many was:

CSCtb70375    SNMP needs to alert user of DNS connectivity issues

<B>Symptom:</B>
If  DNS is not configured or misconfigured the SNMP walk/get operation on that server  will fail with time out.

When an application queries CUCM via SNMP and DNS is not configured correctly, it will timeout and not respond as expected.  No administrator alert is sent to notify them of this timeout/issue.

<B>Conditions:</B>
CUCM with misconfigured DNS (or DNS server down/slow to respond)

<B>Workaround:</B>
Configure a working DNS server


This bug was (C)losed without a fix because it’s primarily a misconfig.

From Syslog, we can see lot of "DBLException" with reason code 746 (on Pub and Sub)

From knowledge database, similar cases of "DBException with reason code 746" have been solved by cluster reboot or Subscriber re-build.

try ‘risdb query…’ commands from CLI on cucm. restart ccm process, or ideally whole cucm server.

We are getting a genErr all of a sudden when trying to do phone refreshes. String is correct and tried using SNMPv3 also.
Have restarted InformaCast and restarted SNMP Agent on UCM.

Anything else shy of a reboot followed by a possible TAC Case?
