Yes.. the file on (system A) is constantly receiving data nearly around the
clock.

physical file building ?
Did you create the DDM file using SNA (the default), or
TCP/IP? We've
discovered that TCP was much faster for DDM copy
files. But we also have 2
lan cards and the TCP is using the gigabit
ethernet.
Perhaps this might also be better served by a Mimix like
solution. This
would keep the files in sync on a transactional
basis. Or, is the file on
systemA filled with the data all at
once also?

Hi All,
There's a process that I am analyzing that
involves large volumes of data
records arriving in one (system A) AS400
physical file. Then another
(system B) AS400 that is attached to this
physical file on (system A) via a
DDM file which resides on (system
B). This process that runs on (system B)
then uses this DDM file and
simply transfers the data that arrived in the
physical file on (system
A).
Lately this process that transfers data between the two systems is
lagging
behind to the tune of millions of records. These lags are
happening at
heavy system use times.
I am wondering if there is an
(overlooked by me) CRTPF option that I could
add to the (system B)
receiving physical file when it's built weekly that
would minimize this lag
on receiving data records? ..possibly ALLOCATING
THE STORAGE or
something?
I have been directed to simply break the process in two
(duplicate it) in
order that the 2 duplicated jobs could run concurrently
on (system B), and
then the (system A) physical file would require 2 file
members in order to
attach two different DDM files to.
FYI) These
AS400's I am talking about are not farty little boxes they are
big
AS400's.
Any suggestions or comments appreciated.
