Running CPSM tasks on Open TCB to make sure user transactions can run normally when CPSM task is hang.

Customer encountered some problem while running a CPSM API batch program. During the batch program execution, CPSM tasks are activated on each MAS region to collect resources. Due to some reason, large page in/out happened to Data Space, which caused CPSM task hang for several seconds. Since the CPSM task is running on QR TCB, in that time period, the user transaction can not run any more. The business is affected for the whole CICSplex. Is it possible to run CPSM tasks on open TCB? So that the customer business transaction won't be affected due to QR hang?

    Whilst this requirement is valid, based on our current plans and priorities, it is not likely that this could be implemented in the next 12 months, or in the next CICS TS release. Correspondingly this requirement is being declined at this point. The requirement will be kept in the RFE system and might be reassessed in the future. You also have an opportunity to resubmit in twelve months time if you wish it to be reconsidered then.

    It is a long term aim to be able to run CPSM code on an open TCB. At the moment this is not possible. Firstly the CPSM code needs to be made threadsafe. Secondly we need to make sure all the CICS call the CPSM MAS agent uses are threadsafe to stop processing having to switch to QR TCB to action the request.
    This is a candidate for a future release, however, it will not be in the next release beyond CICS TS 5.1
