Re: SQL stored procedures and activation groups via JDBC

Why is it a "bad idea"?
Why do you need to "clean up" these programs? I suppose if they're designed
to be cleaned up by some external action like RCLRSC or RCLACTGRP, I'd
compile them with ACTGRP(*NEW) and be done with it. I'd also say that's a
terrible design (depending on the invoker to clean up your resources).
That said, if you are returning a result set with your stored procedure
(i.e. open cursor), I'm not sure the ACTGRP(*NEW) will work... it's worth a
test for that scenario.

Can you describe what the problem really is? Is something not being
committed or being rolled back when it's not supposed to?

Subject: SQL stored procedures and activation groups via JDBC

Hi, all:

An IBM i5/OS customer is running DB2/400 SQL stored procedures from a PC via a Java-based client using JDBC ...

This runs in the QZDASOINIT job -- the top level program is QZDASOINIT, which is itself an ILE *PGM created with ACTGRP(*CALLER) but for some reason it runs in the default activation group (*DFTACTGRP) ... :-o

The problem is, they have commitment control, triggers, etc., and the application programs, triggers and stored procedures etc. are all writtin in ILE RPG IV and compiled using CRTRPGMOD and CRTPGM and set up to run as "true" ILE programs with ACTGRP(*CALLER) as they were never intending to run them in the *DFTACTGRP.

Does anyone know how IBM suggests to support this kind of environment, when accessing stored procedures via JDBC? Apparently, because QZDASOINIT is running in the *DFTACTGRP, this is causing these ILE programs to get activated into the DAG, which is of course a "bad idea" and there is no way to "clean up" these programs, e.g. via RCLRSC or RCLACTGRP, and so the jobs in the connection pool just keep growing and growing (in terms of their storage requirements).

Any suggestions, hints or tips would be appreciated.

Thanks,
