changed default for APPCMAX in DFSDCxxx

The default APPCMAX=(5000,1000000) in DFSDCxxx is too high. The value 64_bit_max should be much smaller, may be 0.
With the current default IMS installations can end up with an IMS SBND (sick but not dead) situation. IMS storage is protected whereas APPC/zOS can encounter Abend SEC7 RSN=000090031 (which is an APPC out of storage situation) long before DFS4157W (IMS reaching APPCMAX) is issued. Average APPC message size influences how early this APPC out of storage occurs.
LUM TCB of IMS abends SEC7 , but IMS does not come down.

    Hi,

    Thank you for your interest in keeping IMS a vital and successful product. Software development has continuously evolved during IMS’s lifetime, and so has IMS itself. We have kept pace with, adopted, and implemented many industry standard best practices within our organization, including Continuous Delivery, Design Thinking, and Agile.

    When choosing new features to add from the list of requirements in our backlog, we assess which will bring the most value to as many clients as possible and prioritize those.

    After reviewing this request for enhancement and assessing its potential value, our decision is address this issue within APAR PH21436. We believe this is a more appropriate action for this item given the details provided.

    Have a great day!
