Re: We have a mystery -- MIDRANGE-L

Hi Mike

how long beforehand does the process that generates the records run and
what happens in between ? I am assuming there is a commit taking place
befor eyou are tryign to get th records with the program experiencing
errors.

is the file being journalled and does the add entry in the journal have a
timestamp before or after the schedueld program ran ?

Another thing to check that I seem to recall happening way back in the past
was a programmer makign changes to the FRCRATIO parameter on a file that
exhibited similar symptoms; maybe that is something to look at (this is
more of a SWAG)

We have an RPG with embedded SQL program running in a CL program that has
calls to multiple RPG programs. This CL is run from the job scheduler late
at night. We were having issues with this night job that looked like it was
not running the one RPG app but when run during the day by itself it would
work perfect. So we added a trace to the program to see what it was doing
at night. It showed that no data was being read from the SQL fetch command.
When it was run by itself during the day it showed it read thousands of
records. The next debug step we did was to have the main CL that runs at
night CALL the RPG app and then also do a SBMJOB to call the same RPG app.
When run from the main CL with a CALL it read nothing. 2 minutes later when
it was submitted it ran fine and read thousands of records.

We are stumped. Has anyone ever seen this happen before? There are no
overrides or explicit sharing of open data paths.
