1017.0. "V2.2-11 : no answer from ..." by BACHUS::BANKEN () Wed Mar 12 1997 11:32

Hello,

Can someone help me to troubleshoot the 'no answer from' problem.

Consolidator 2.2-11 Alpha Server 1000 	
Transport : TCP/IP

  Node    Status    Class            Version  OS Version
  NVQ     Enabled   APPL_CLASS4       V2.2-11  OpenVMS V6.2-1H2      AXP
  NVP     Enabled   APPL_CLASS4       V2.2-11  OpenVMS V6.2-1H2      AXP
  NVO     Enabled   APPL_CLASS4       V2.2-11  OpenVMS V6.2-1H2      AXP
  NVK     Enabled   APPL_CLASS2       V2.2-03  VMS V6.1              VAX
  NVJ     Enabled   APPL_CLASS1       V2.2-03  VMS V6.1              VAX
  NVH     Enabled   APPL_CLASS4       V2.2-11  OpenVMS V6.2-1H2      AXP
  NVG     Enabled   APPL_CLASS4       V2.2-11  OpenVMS V6.2-1H2      AXP
  NVF     Enabled   APPL_CLASS3       V2.2-11  OpenVMS V6.2          AXP
  NVE     Enabled   APPL_CLASS1       V2.2-03  VMS V6.1              VAX
  NVD     Enabled   APPL_CLASS1       V2.2-03  VMS V6.1              VAX
  NVC     Enabled   APPL_CLASS1       V2.2-03  VMS V6.1              VAX
                                                  
no answer from 2 particular agents, one is a VAX (2.2-03) the other is an 
Aplha (2.2-11). Network nor system load seem to be the problem.

What is the difference between 'no answer from' and 'unreachable' messages

Thanks in advance,

Alain.

	The "No answer from <nodename>" message is not an event message. It is displayed by the Controller continuous display when o It awaits data from the Consolidator about the currently polled node... o ... and the Consolidator takes too much time to respond. (the delay can be tuned using the SNS$SHOW_EVENT_WAITING_DELAY logical name, which should translate to the wished number of seconds, the default delay beeing 60s). Usually, after you get the "No answer from ...." on display, and waited for N * 60s + delta, where N is the number of non-answering nodes (for which the connection attempts will timeout) and delta the time necessary to poll other nodes, you will get the list of event messages on display. Within that list, the event messages of UNR, ORS or OTH type concerning the non-answering nodes should be more talkative... Best Regards, -- Olivier.
