Stuart, are you suggesting that, in an NDPS environment (for example), =
BOTH a
"driver spawned" job monitoring client application (like DocWise) AND a=
NOS
provided monitoring paradigm (NDPS) will be in operation at the same ti=
me on
the same job? Why would the end-user want 2 ways to monitor the print j=
ob?

Part of the decision to use "last encountered" jmJobSubmissionID was to=
keep
the agent simple, yes, but this decision was also based on the premise =
that
only one "tightly coupled" monitoring application need be in control. T=
his is
not to say "out of band" applications can't still monitor - just not in=
the
"pin point" fashion provided by the jmJobSubmissionID to jmJobIndex map=
ping
table.

I don't strongly object to moving to a design where multiple
jmJobSubmissionID's map to one jmJobIndex. But, I'd like to be convince=
d there
is a practical use for this. Could someone offer a high level diagram o=
f a
practical system where the client is getting job progress information f=
rom two
sources, simultaneously?

Ron,

I am increasingly uncomfortable with the agreement to use the last
submission id encountered. I believe the original decision was based o=
n
the idea that it was the simplest solution, but your write-up on the
Proposed Rules for jmJobSubmissionId shows that this solution is not so=

simple or straight forward after all.

I can see the possibility of an application that works closely with the=

driver, such as HP's DocWise, using the driver created jmJobSubmissionI=
d
for job monitoring. It is clearly undesirable for something downstream=
,
such as NDPS, to then stomp on the jmJobSubmissionId created by the dri=
ver.

Allowing multiple jmJobSubmissionIds to point to the same jmJobIndex se=
ems
to be a more straight forward solution. I know the consensus was to no=
t
re-open this, but maybe others are having second thoughts. Can someone=

refresh my memory on the negatives of allowing multiple jmJobSubmission=
Ids?
