Add HEAPZONES Setting in CICS LE Ceeropt Module

Hello,
z/OS 2.1 introduced LE HEAPZONES Option to add a check zone to heap allocations.
In Test-Batch I can default to a non-zero HEAPZONE in DD:CEEOPTS in JCL PROCs

But this cannot be set at CICS Region level, except with CLER Transation after startup. There is no API to change this setting.

I´d like to put this setting into CEEROPT Region Override Modul.
This parm has a negative impact on performance, but this may have no relevance for testing.

Please add support to allow this.

    Sorry we have to decline this requirement:
    1. to maintain compatibility behavior for HEAPZONES. Users may expect that it should be always ignored in CEEROPT
    2. to avoid miss use risks
    Thank you.

    Hello, if I want to set the Heapzone Check as default in test regions and the only option to acitvate this is CLER, then i have to reenable it every time such a region is restarted. There is no automatic way to do this. We have 30 test regions, its not an option to enter every region after restart and use CLER.

    Also HEAPCHK can be activated in CEEROPT, which i think has a more severe influence to Heap performance than HEAPZONES

    We also init heap + stack in test regions with a bad value to find uninitialized variables with a higher possibility.

    Hi Horst,
    Yes you are correct that this option has some negative impact on performance, and is more suitable to be set in a test envrionment. So we have some restrictions to make sure it will not have big impact for the whole system on any settings by mistake.
    As to CLER and CEEROPT, we think that CLER can be turned on/off and checked easily in test environment which should be enough, while CEEROPT is not that easy and can be error prone.
    I'd like to hear your opinions, why do you prefer CEEROPT over CLER?
