CLIENT.DEFUNCT

Advisory

Subject Name Syntax

_RV.ERROR.SYSTEM.CLIENT.DEFUNCT

Purpose

Client transports receive this advisory when they become unusable as a consequence of deleting an RVDM subject map.

Background

Limitation on Computers with Multiple Network Interfaces in TIBCO Rendezvous Administration discusses a limitation—all the client transports of a daemon that use a particular service must also specify the same network parameter.

RVDM subject mapping discards application-specified network parameters, and replaces them with multicast groups, effectively transcending this limitation, and enabling transports to communicate that would otherwise be unable to co-exist.

In this situation, deleting the subject map causes the existing client transports to revert to their own network parameters. If these network parameters conflict with one another, one transport (T1) determines the fate of the others:

•	Transports with the same network specification as T1 continue to function properly.

•	Transports with conflicting network specifications become defunct. They receive this advisory, and stop functioning.

 

Deleting a subject map could cause this effect at several managed daemons throughout an enterprise. The surviving network specification could be different (and probably will be different) at each daemon. As a result, the surviving client transports at the various daemons will probably not be able to communicate.

Remarks

Only the defunct client transports receive this advisory.

This message is an error—the daemon stops communication for the affected transports.

Message Fields
