[Css-csts] 'invalid procedure instance identifier' should lead topeer abort

[Martin Götzelmann]

Dear John,
 
I think what you propose is the only way get to a consistent and not too complex specification. I believe this definition was the result of one of those discussions we regularly have about the concern that PEER-ABORT is a too strong response to a configuration mismatch between service user and provider. In most of the cases it turns out that continuing in such a case is either overly complex or very error prone. Therefore, I personally think aborting the session is the best approach anyway although it might be annoying during tests. 
 
Kind Regards, Martin

Subject: [Css-csts] 'invalid procedure instance identifier' should lead topeer abort



CSTSWG colleagues ---

The Standard Operation Header has the diagnostic 'invalid procedure instance identifier', which is defined as

'invalid procedure instance identifier' - the submitted procedure instance identifier is invalid as a result of

-        procedure type is not specified by the service,

-        the combination of procedure type and instance is not in line with the configuration of the provider;

 

However, because it is an SOH diagnostic, this can only be returned for confirmed operations: e.g., a TRANSFER-SERVICE invocation referencing a procedure type that is not used by the service, or containing a procedure instance number for a procedure instance that hasn't been activated, would presumably proceed without correction. An error of this type seems to be at least as serious as the other conditions that result in a peer abort, so even for a confirmed operation it would seem inadvisable to simply reject to invocation and continue on. This diagnostic should be moved from the SOH to the PEER-ABORT operation, so that when the condition is present it results in a peer abort regardless of whether the operation is confirmed or not. 

 

Best regards,

John
