Hi Magen,
Brief design points for a similar home-grown product that is 10 years in
production:
a) define a DB2 "workload" table where each batch process will post the DS-name
of a dataset containing the "new work"; in our case this table is populated by
the last step of the NDM transmission JCL [or ANY other job that wants a
sequential file to be "processed"], so whenever a new batch file is created,
its name is inserted in the DB2 table
b) develop a long-running multi-tasking job, that would have a single task to
periodically scan the above DB2 table loking for "new work" and once found,
attach yet another subtask to "process" this particular "work"; in our case
this subtask is merely copying the original sequential file to an MQ queue
drained by multiple CICS draining tasks, while the whole job stays up for a
full week before getting recycled; one more subtask is design to process
operators commands that allow to pause, resume, stop transmission, etc.
[actually, there are 2 such subtasks, the second is "listening" on an MQ queue
designed to be populated from a CICS screen]
c) you can also add much more granular control to the above by having some
external "rules" [in our case DB2 tables] that would dictate exactly how to
recognize and manage a particular data type [how to validate data headers, what
MQ queue(s) to choose, how to recover after a failure, etc.]
Please, e-mail me offline if you'd like a clarify some questions.
HTH,
-Victor-
==============================================================================
In order to make systems more "online" we are looking for a way to
run the process for each record all day long instead of a daily run,
and doing so with minimum as possible application changes.
