RE: Poor Response Times ... BPCS INV

[Albert Lopez <alblopezc@xxxxxxxx>]

I have a savefile that contains a library with a command that creates a set of 
logical files for BPCS 6.04
which improves the performance of the programs. This set of logical files was 
created after investigating
the most used programs/files and the acces key used in the programs.
I installed this logicals in several  companies in Spain .Anyway, the way each 
customer
executes the programs is different ( eg. is not the same pick by line than by 
order, the key to access file IPP
is different), so after installing the logicals in the customers we did a work 
of investigation to see what was
improved and what not. And for the processes we still needed to improve, the 
way was easy:
do a PRTSQLINF for the programs, and check wich SQL's are creating access path 
or have high estimated query execution
time; then create a logical that covers this querys.

If anybody wants this library I can send it via e-mail. Is stored in V4R2.

>From version 6.04 and onwards the package is written enterally in
AS/Set+embeded SQL
therefore the performance is worse .
with subfile you can not go back once you positioned you have to
reposition...
like i said if you build the right logical ith ecl ech sih and so on the
package will start to react like you know from version 4 i have been thru
that in December 1998 when i upgraded v4.2 to 6.04 .
also think of upgrading the machine by disk size ( source are huge inv500d2
can not be seen thru regular seu because it is more then 32764 lines..) and
memory i did that in all 3 sites.
good luck
Danny

Al Mac - many thanks for a comprehensive reply.
I've got a few things to check now.

BEWARE - V6 seems to read ITH in a different way to V4 (we upgraded from
this).
V4 seems to get a 'screenfull' of data & read more when the user request
another page - response-times were OK here with this....
V6 seems to get everything (for that part number) & gives little delay when
the user requests another page - just a huge delay initially....
