Are the SQL monitors already on the system? How do you use them?

Does sound like an index problem.
I had the same issues a few years ago with 1/APY - report payments due
also, went from seconds to hours to run I used one of the sql monitors
to view what was being processed, it suggested what views to create.
Created the views and that did fixed it.
For the 1/APY issue I created 2 views,
R PLR15 K LOGI15 K CONO15 K SUPN15 K
CURN15 K PDUE15 K ETYP15 K LREF15
And
R PLR15 K LOGI15 K CONO15 K
SUPN15 K RSTS15
Worked for me, your milage may vary.

Steve -
Did you just upgrade your operating system to V6R1 by chance?
We never had performance problems in the past, as our AS/400s in
recent years has been oversized.
We upgraded to V6R1 two weekends ago and I am now getting sporadic
reports of jobs that appear to be stuck. When I investigate it's
always a RPG program with embedded SQL. The jobs are running, they
are just VERY slow.
One job in particular is 1/APY - report payments due. It used to take
only 15-20 seconds to complete, and it now takes over 45 minutes.
When this job is running, our CPU jumps to 75+ % utilization. Prior
to V6R1, our AS/400 was rarely above 10%
When this job is running, the program stack indicates that it's called
a program in QSYS called QSQROUTE.
I signed onto Fix Central and we have all of the latest PTFs from IBM.
I am not sure what to do at this point.

We are at 3.5.2 SP3. A user complained to me about the performance_______________________________________________

(Routes/Structures). This has been occurring forever but we are just
now hearing about it. It was taking about 20 seconds to change the
quantity on one part but when they would change two of more
quantities then press F8 to update it could take 3 or 4 minutes to
complete the update. I had a vendor look at the application and they
found an issue with the embedded SQL. They found and fixed the issue
in program DB590 and the update is now nearly instantaneous. In this
case they had to create a new logical and modify the SQL.
Today another user complained about the performance, that has been
occurring forever, when using the "Routes/Structures Audit" (MDE
option 8). After a part/route is entered and a change is selected
via "2=Route Structure Inquiry" and enter is pressed on the next
screen, it can take up to 5 minutes to get to the screen titled
"Process Route Audit Inquiry
- Inputs". The issue appears to be with various SQL statements in
program DB561.
There seems to be a pattern here and I know there are many other SQL
programs in System 21 and I now wonder if this performance issue is
occurring in other programs but our users have just learned to live
with it. In the 8/MDE problem above the users have simply chosen not
to use the option.
Has anyone else experienced similar issues with embedded SQL and
maybe found a fix? Unfortunately, we do not know how to troubleshoot
embedded SQL issues. I know my vendor can look into it and fix it
but wonder if there is a general fix for these type of issues with
embedded SQL that my programmers can look into.
Thanks in advance for your input.
