TH> I've annoted your updated definitions to tie back to the agreed spec
TH> to help us at the meeting.


TH> I've added the names and numbers of the agreed objects from the  
TH> Portland meeting as reflected in the jm-spec.doc and jm-spec.psr 
TH> that I posted a week before the August meeting in San Diego 
TH> that was cancelled at the last minute. 
 
TH> Then we can use these descriptions as we review the specification 
TH> posted in ftp://ftp.pwg.org/pub/pwg/snmpmib/jobs-mib/

Subject: Updated Definitions for The Job Monitor Project Sender: owner-

This paper summarizes my understanding of the current status of the 
proposed objects for the Job Monitor project.  I believe that this 
document is necessary since the JMP minutes for the last two meeting 
were never published. 
 
TH> Not true, since the updated spec with the agreements from June 
TH> and July were each posted a week before the next meeting. 
TH> see jm-spec.doc and jm-spec.psr. 
 
I have also included a revised set of definitions for the objects to 
replace the DPA set originally provided by Tom Hastings.  My objective 
in writing these descriptions was to develop a minimal definition that 
could be expanded to a final form.  I feel that the DPA definitions are 
extremely restrictive and limiting in many areas.  We need a concise set 
of definitions that are applicable and useable with any job submission 
protocol and model. 
 
TH> I agree that our actual MIB wants to have concise definitions 
TH> along the lines that you propose.  But I want to first get agreement 
TH> on what objects we want and then we can refine, simplify, etc. 
TH> But if we attempt to worksmith the descriptions at the same time 
TH> as we are trying to decide what objects we need, we will have too 
TH> difficult time and progress will be too slow.   
 
TH> Also some of these definitions are actually different from the ISO  
TH> DPA semantics. 
 
TH> Also I don't want to debate names of the objects, until we have 
TH> the definitions agreed to.  Naming should come last.  Also we need 
TH> to understand what information a single job will have in a  
TH> (doubly indexed) table as opposed to a scaler (one column in the job 
TH> table) for the job.  Separate tables may want to have a different 
TH> significant word, such as "job" for the scalars and something else 
TH> for the tables, such as "doc", or "acc". or something.   
TH> So we need to wait to name our objects until after we agree on the 
TH> specification and the number of instances per job. 
TH> Also we may want to have a common prefix on each object, such as 
TH> "jm" for job monitoring, like so many other MIBs. 
 
TH> So the order for processing should be: 
TH> 1. What objects do we want using DPA definitions to indicate what  
TH> we mean using jm-spec.doc and jm-spec.psr. 
TH> 2. What objects are mandatory, what are conditionally mandatory, 
T>     what are in a second MIB. 
TH> 3. Which objects are one instance per job and which are multiple 
TH>    per job. 
TH> 4. What is the syntax for each object. 
TH> 5. What is the simplified description text for each object. 
TH> 6. What is the name for each object. 
 
Since I will not be able to attend the NYC meeting, I trust that Tom 
Hastings will make use of this document in the session devoted to the 
Job Monitor Project.  (Note that my absence is not due to a fear of the 
Big Apple, the expense of the meeting or the limited attendance by 
others.  I was not able to attend the San Diego meeting due to a similar 
situation.  And that meeting had none of the above problems!)  I hope to 
see everyone in New Orleans!!! 
 
TH> I've indicated the agreed descriptive name with the 
TH> number in the August agreed spec, followed by the ISO DPA name 
TH> in square brackets. 
------------------------------------------------------------------------ 
 
JOB IDENTIFICATION OBJECTS: 
 
TH> 1. Job client id (on the original client) [job-client-id] 
 
1. jobIdOnClient: (String, max TBD)  This object identifies the job on 
the device that initiated the job.  The format and method of generating 
this object is expected to be defined by the Job Submission protocol and 
is beyond the scope of this document.  This object must include 
sufficient information to uniquely identify the job on the network 
visible to the client and target device. 
 
  *** THE FOLLOWING TWO OBJECTS ARE OF QUESTIONABLE VALUE ***  
 
 
TH> 4. Job downstream id (downstream from the server implementing this 
JM MIB) on device (printer [job-identifier-on-printer] 
 
2. jobDownsteamId: (String, max TBD)  This object identfies the job on 
the next downstream server. 
 
 
TH> 2. Job upstream id (on upstream from the server implementing thise 
JM MIB) [job-id-on-client] 
 
3. jobUpstreamId: (String, max TBD)  This object identfies the job on 
the next upstream server. 
 
  *** PROPOSED ALTERNATIVES TO THE ABOVE TWO OBJECTS *** 2. 
jobIdOnPktSrc: (String, max TBD)  This object specifies the identifier 
as assigned  by the entity that is currently sending the data set.  The 
value of this object will change as the data set moves from server to 
server. 
 
3. jobIdOnPktDest: (String, max TBD)  This object specifies the 
identifier as assigned by the entity that is currently receiving the 
data set.  The value of this object will change as the data set moves 
from server to server. 
  *** ARE EITHER OF THESE PROPOSALS REALLY NECESSARY ??? *** 
 
 
TH> 3. Job current id (on the downstream server implementing thise JM 
MIB) [job-identifier] 
 
4. jobIdOnDevice: (String, max TBD)  This object identifies the job on 
the device which is currently processing the job.  The processing device 
includes, but is not limited to, printers, faxes, scanners, spoolers, 
and files servers.  The value of this object may change for systems that 
include intermediate devices such as file servers and spoolers. 
 
 
TH> 5. Job types (print, fax, scan, etc.) - multi-valued [new] 
 
5. jobType: (enum)  This object specifies the type of service requested 
to process the job. 
 
 
TH> 6. Job owner (User name that originally submitting print job) [new] 
 
6. jobOwner: (String, max TBD)  This object identifies the client that 
submitted the job.  The method of assigning this name will be system 
and/or site specific but the method must insure that the name is unique 
to the network visible to the client and target device. 
 
 
TH> 7. Source channel type (index of channel row in enum from Printer 
MIB) [new] 
 
7. jobChannel: (enum)  This object defines an equivalent to the print 
job delivery channel as defined in the Printer MIB. 
 
 
TH> ?. This is new but replaces the "source port" that we agreed to 
TH> delete in Portland. 
 
8. jobMagicCookie: (??)  This object defines the protocol path from the 
physical layer to the jobChannel.  The format of this object will be 
similar to the work in process for the Printer MIB. 
 
 
TH> 9. Job name (assigned by job owner) [job-name] 
 
9. jobName: (String, max TBD)  This object is an ASCII text string which 
identifies the job.  This is expected to be human readable form of 
jobIdOnClient. 
	*** IS THIS OBJECT SIGNIFICANTLY UNIQUE TO BE OF VALUE ??? *** 
 
TH> Its purpose isn't uniqueness, but helps a user distinguish between  
TH> his various jobs.  Its job-owner that distinguishes between jobs 
TH> belonging to different users. 
 
 
 
TH> 10. Document name(s) (or file-names) [document-name] 
 
10. jobDocument: (String, max TBD)  This object defines a name for the 
job.  The name is typically expected to be the file or file/path name of 
the source of the job.  The name does not need to be globally unique.   
(The name would typically be repeated if several jobs from the same file 
are simultaneously in the jon queue.) 
 
 
TH> 11. Date/Time of job submission by job owner [submission-time] 
 
11. jobSubmissionTime: (DateAndTime)  This object indicates the time and 
date the job was submitted by the client. 
 
 
TH> 12. Job comment [job-comment] 
 
12. jobComment: (String, max TBD)  This object provides a user 
defineable, application specific field.  (Post-it note) 
 
 
TH> 13. Device name (Device-specific name of device) [printer-name-
requested] 
 
13. jobDeviceName: (String, max TBD)  This object specifies the 
administratively defined name of the target device. 
 
 
JOB PARAMETERS:

  *** SINCE THIS IS NOT A JOB SUBMISSION PROTOCOL *** 
  *** PROPOSE THAT ONLY THE ITEMS THAT INDICATE STATUS OR *** 
  *** PROVIDE ACCOUNTING INFORMATION BE RETAINED !!! ***
