NEW ISSUE: Editorial (maybe) RMS MessageNumberRollover behavior unclear

["Bob Freund-Hitachi" <bob.freund@hitachisoftware.com>]

In the June 26 version of WD 15 in Section 3.4 “Sequences” starting at line 581 states

 

“If the message number exceeds the internal limitations of an RM Source or RM Destination or reaches the

maximum value of 9,223,372,036,854,775,807 the RM Source or Destination MUST generate a

MessageNumberRollover fault. In this case the RM Destination should continue to accept , and the RM

Source should continue to retransmit,undelivered messages until the Sequence is closed or terminated.”

 

1) It is unclear under what circumstances the RM Source generates a MessageNumberRollover fault

 

Should the RM Source generate an unTransmitted fault if a message is Sent that exceeds the RM Source’s internal limitation?

Should the RM Source transmit a fault if a message is Sent that exceeds the RM Source’s internal limitation?  If so, what should the RM Destination do with it?
Should the RM Source generate a MessageNumberRollover fault at all?

 

2) Assuming that the RM Destination Transmits a MessageNumberRollover fault upon receipt of a message with a MessageNumber that exceeds its internal limitations or the big number cited, whichever happens first, what mechanism is used by the RM Source to close or terminate the sequence?

 

Proposal:

New Text:

 

“If the message number exceeds the internal limitations of an RM Destination or reaches the

maximum value of 9,223,372,036,854,775,807 the RM Destination MUST Transmit a

MessageNumberRollover fault. The RM Destination should continue to accept, and the RM

Source should continue to retransmit, unacknowledged messages until the Sequence is closed or terminated.

 

“If the message number exceeds the internal limitations of an RM Source or reaches the

maximum value of 9,223,372,036,854,775,807 the RM Source MUST generate a

MessageNumberRollover fault. The AS SHOULD Send no further messages.  The RM Source should operate normally and the state of the Sequence is unchanged.

 

This proposal assumes that some coordination between the AS and the RM Source will exist that will determine the timing of Sequence closure.
