to process this data for /months/.
I would have expected him to finesse the algorithms, handling dataset
contention etc on test data, or possibly just a handful of examples of
live data - and as you say, I'd have hoped that that would have been
anonymised.

I have a dataset that is allocated to multiple jobs but with a disp=shr
And I am getting contention messages MIM1039I I was always under the
impression
That if the dataset was allocated with disp=shr
I have to believe that MIM would not issue a contention message if all the
allocations were
t;. Company and management culture and practice have a lot to do with how
hard that is to do.

Jeremy,
I have to disagree with you here about access to read (not modify) production
data by application developers. Full read access to production data
(especially when the quantities are very large and cannot easily be copied

Richard was the one who resolved by problem I allocated the datasets in rexx
and did a submit
The contention was between the batch jobs and my TSO session IKJEFT01
When I did the FREE FI problem was resolved
Thank you Richard

You seem to have

That won't work if two jobs simultaneously try to write to the file.
You might not destroy the file, but you will lose the information
Richard
Thank you I see 2 jobs running now without contention messages

I am doing a file search over 2000 files looking for specfic data since there
are so
Many files I broke them up in to multiple
Jobs
The rexx exec calls the catalog search program IGGCSI00 for the input files
They are VB files
The output file is shared among multiple jobs whenever I get an equ

That if the dataset was allocated with disp=shr
It could be used among multiple jobs
Without problems
