Just off the top of my head from having a similar issue a few
years ago, you may need to be watching two ECBs (EVENTS). But I'm
not sure that the STIMERM won't cause a squawk when you have the
task end.
And I think you will have to pass the address of the ECB you will

The ‘B’ task issues a STIMERM WAIT=YES
Task ‘A’ terminates, but gets the A03 abend since task ‘B’ still active.
How can task ‘A’ communicate to the subtask ‘B’ that it (task ‘B’) needs to
terminate? Task ‘B’ is in the

Exceptions might be sockets, descriptors, pipes, and NFS. And not all

While BLKSIZE has no meaning for linear data sets, it *does* have meaning for
the BSAM compatibiliy interface.

Hi Jon,
Thanks for your thoughts, but I'm not trying to
decide if I should use FACILITY. I'm trying to
decide how I should go about discontinuing using FACILITY.
Based on suggestions from others on this thread,
I've made the decision to switch to using a class named XFACILIT.

Incorrect, BLKSIZE has no meaning for VSAM linear datasets. By definition, "All

Gadi, Binyamin, Rob, Ed, Phil, Hayim and Peter!
Thank you all for good information and a GREAT discussion!
Like some of you, I also am very sensitive to the customer's burden,
so while creating a "$XDC" class perhaps might be "easy", to
paraphrase Peter, why would I make a customer do that
I’m using test to debug this thanks

You have to use the RSMDATA subcommand to see the above-the-bar allocations. As
a starting point, see RSMDATA HIGHVIRTUAL .

While some have suggested creating your own class, there is an off-the-shelf
class suitable for XDC's use: XFACILIT.
- Maximum resource length is 246
- Default return code is 8 (everything is denied if the resource is not defined)
This is just as suitable as creating your own class name, and

Although setting up your own SAF class is not difficult, it is another step in
the installation/migration process and my instinct (bearing in mind the
squeeze on staffing resources) is always to tend to "zero-config" wherever
possible.
