Well, the VROSIF file is actually quite small, it shouldn't have more than 
5.000 records most
of the time.
The PC application has been programmed without consulting us AS/400 people. In 
some
logfiles I see the following nonsense:

       select * from vrosif where order=4711
       update vrosif set sdat1='131102' stim1='14:02:30' where order=4711
       update vrosif set siid='020' user1='SORTER' where order=4711
       update vrosif set sistat='43' where order=4711

(not correct sql-syntax, just to show what happens).

Is it allowed to shoot that programmer?

I will look into these settings, but I think it is already active. There is a 
QZDASOINIT job
active since monday that is reused whenever the PC app disconnects...
About 10 times a day I see a new QZDASOINIT job starting for that ODBC user, 
but it
immediately ends again and has no activity in the joblog.

Thanks for your suggestions,

Oliver
