You're so right - I have been up against this one, big time.
If you want only a single row result set, you can get round it by:
a) changing the stored procedure to return output parameters
Now these are not supported by Domino (one step forward two steps back) so
b) write another RPG stored procedure which runs on the web server & which
simply calls the remote stored procedure & converts the output parameters
into a single row result set - Eureka! (It does work, I promise, although
you'll have to use some ticklish SQLRPG programming in your calling stored
procedure.)
If you want a multiple row result set, you will have to move the stored
procedure and the RPG programs onto the web server and access the database
via DDM, which is probably infeasible in a BPCS environment. But maybe you
only want a single row result set!
My perception is that this is not fixed for AS/400-AS/400 connections in
V5R1 but may be later.

Rob,
A result set is not supported when using a called stored proceedure
using DRDA.
It sounds like you are running into this limitation.

Subject: Directly accessing DB2/400 data from Domino across 400's
We had a Domino server, and DB2 data, on the same 400. This is our
development situation. In our live we have Domino on 1 400 and the DB2
data on the other. We have a database, which accesses data in a BPCS
environment. Runs a BPCS report, converts the report into a disk file and
sucks the data back into Domino. All from pushing a Domino button. Works
great as long as the DB2 and the Domino are on the same 400. When we moved
the Domino database into production, but left the data in development, it
failed. Sort of. It still called the BPCS programs, ran the report,
converted the report back into a disk file. But it's supposed to pass us
the name of the file back and we execute further script to bring the file.
This is how it passes the name of the file back:
C/EXEC SQL
C+ SET RESULT SETS ARRAY :Parm1 FOR :Row1 ROWS
C/END-EXEC
The difference we notice in the joblog is that when the Domino is ran from
production versus being on the same development 400 is that two additional
messages appear in the joblog. They are:

I have a pmr opened with Domino: 79730,500, but I'd thought I'd pick your
brains also.
