[bt-spec] Issue 95: fault data for WrongState FAULT

[Tony Fletcher <tony.fletcher@choreology.com>]

Dear Colleagues,

 

Issue 95: fault data for WrongState FAULT

Status: new
Date added: 11 Dec 2001
Category: minor technical
Submitter: Jim Webber, HP
Description:
In the table on page 60/61 of version 0.9 there is a table which contains fault types and their respective fault data. For the fault type "WrongState" there is no corresponding fault data.

Is this an error? Shouldn't it at least be a free text description perhaps giving some information as to the unexpected state which resulted in the error?

Tony's thoughts:

This comment in stating that the table which defines the Fault Type parameter, its meaning and the corresponding Fault data parameter of the FAULT message does not have an entry for Fault Data against the Fault Type of Wrongstate.  Several of the definitions of other (abstract) messages indicate wrongstate situations that could occur.  However there is no complete list of Wrongstate values anywhere.  Several of the other fault types do have a fault data entry of "Free text explanation".

 

Proposed solution:

In the FAULT  message definition, in the table of Fault type - Meaning - Fault data  in the row for Wrongstate add in cell for the Fault data column "Free text explanation".

 

[Perhaps add a note to say that it is recommended that this is of the form either  <<letter digit>> where this is the state designation from state tables in the BTP specification, or of the form   <<MessageType sent>> or <<MessageType received>>

]

 

Best Regards     Tony
