Re: MCH0601 with QMHRDQM in V7R1

Hello :-)

I am totally guessing here, but are you really just calling all these
API's and not checking the return code? Or is that just a cut down version
for us?

The message below translates (in my weird world) into "The userspace
wasn't created so, I can't point to it"

Step through this thing in debug (or check the job log for user space
creation errors)

The major hint here is that the pointer in the error message is zero and
the amount you are adding to it is EFFDFF, or 15728127, so that says to me
the userspace pointer you are getting back from RtvPtrUsrSpc is zero.

Anyway as for why, I'd guess some new authorities on the box?

Hope this helps

Especially check for the use of binary fields in the call. I'm too lazy
(err, busy) to look up the definition, but I got bit by an old API usage
where there were binary fields. Had to switch to INT.

Please show us the API call (and proto if used) plus any structures

used etc.

It is possible that you have a scenario in which corruption has always
been taking place (possibly due to incorrect API usage) but changes in
the
compiler in V7 mean that you are now corrupting something that
matters.

Hi,

I wrote a utility to retrieve messages from a data queue and store
them
in
an SQL table using API QMHRDQM. The utility works fine at V5R4 but
is
failing in V7R1 with the following error. Could this just be a
compilation
issue?

Cause . . . . . : A program tried to set a space pointer, tried to

The space class is X'07'. The space class designates the type of

0.
02-implicit process space for automatic

04-implicit process space for heap identifier X'00000000' in

X'80000000000000000000000000EFFDFF' is a pointer to the teraspace
page

the start of the implicit process space for the
