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.

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
ave a lot to do with how
hard that is to do.

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
I open the file extend I have been tasked with finding data there are certain

again it won’t happen and like I said it’s not production if

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
