DB2 Stored Procedures

Does anbody out there access CA-IDMS using network DML from DB2 Stored
Procedures? I have been asked by the DB2 Developers how to do it and I
had to confess complete ignorance.

I (Partially) understand from the DB2 guys that there are 2 flavours of
Stored Procedure. One runs in the DB2BDBM1 address space and the other
in a WLM managed address space. I get the impression that the latter
woul dbe pretty much like a batch job as far as IDMS is concerned. I'm
not sure about the other one because it sounds more like a kind of CICS
to IDMS communication - a single address space running tasks for
multiple users.

Any info from people who have done it / failed to do it / partially done
it , would be most welcome.

Please explain any DB2 considerations using simple language because I am
in no way a DB2 expert.

Thanks

Re: DB2 Stored Procedures
"From our DB2 guru:

Yep, you can call IDMS from a DB2 Stored Procedure. We use WLM SPs
written in COBOL. The
WLM address spaces are multi user environments and will connect to IDMS
like a batch job.
Have found had to limit the NUMTCBs because of memory issues.
We have had security issues with our home grown security routines but
you will probably
be fine with default security. Essentially, we connect to DB2 from
.net applications and
Call the SPs from there.
There is also an IBM supplied SP, DSNACICS, which allows you to call
CICS trans/programs.
We are using this now, new here, to circumvent the security problems we
have had.
The security problems:
UserA calls a SP -fails with subschema access denied
UserB calls a SP -works because has access.
UserA calls again and uses same, now inactive connection, they
work now because
have UserBs access.

Also found that the ACID of the WLM address space, had to have
all possible access that any user
could possibly have.
Because of this, we only allow public data to be allowed from the batch
like WLM address spaces.

We have CA's Top Secret and, as said before, have home grown routines
that are believed to be causing
this behavior. You may be fine. But it's worth testing. If you do
have security issues, consider
using DSNACICS.
