Hi
I can't add too much tor this, but a few years ago, I tried do something
similar, i.e.
In a multitask supervisor mode server, from the workers sub-tasks ,
call the Xerxes XML parser via CEEPIPI.
Don't remember for all the details, but surly I had also different 46D
abends . In the last version my LE rutime options:
POSIX(ON),TRAP(OFF,NOSPIE),STACK(1M,1M,ANY,KEEP)
A suggestion would be(if possible) to call the LE module without
CEEPIPI, to see how it works with "normal call's".
Completely independent from this Xerxes project, we have tried to use
the zIIP engine from C++ ( with a valid enclave SRB license) , but it was
a "normal" C++ application, so no CEEPIPI. The application was very
complex, and I wasn't able to find a way
to run the code under enclave SRB.
Some small parts (for example the ZIP inflate/deflate) library was
proper to run in zIIP, but it is
generally only a few percent of the total CPU .

I don't know why LE would issue an ESPIE if you told it not to. It
certainly seems from the evidence that something is issuing ESPIE.
And it's issuing it in your state, which is supervisor state, which
therefore will result in the abend you received.
Is it possible that what you think are the options that you provided are,
in fact, not?
This is a possibility and I will check it carefully. However, if
supervisor mode is entered prior to any subtask being attached, the process
runs to completion without abend. The 46d-18 only occurs when the PROCESS
subtask is the only subtask which enters supervisor mode.
My current thinking is that the exception routine needs to be coded in the
CEEPIPI service routine vector. That will be checked next.
As to
You might be asking, why I'm doing this. The answer is that eventually,
I
want to be able to run the C/C++ programs that are setup in the SUB_DP
environment under an SRB. This is documented in Language Environment
Vendor Interfaces (SA22-7568). This will allow me to offload C/C++ code
to
a zIIP engine.
I can say only "maybe". In general, only if you are licensed to do so (and
of course if the SRBs are enclave SRBs).
Agreed on both points. A valid license is hand.
