Exploit 64-bit addressing mode in zWS

We would like to request the implementation of 64-bit addressing mode for zWS to avoid potential S878 storage-related abends.

Our current production zWS controller has a very large and complex batch schedule with a high frequency rate of updates.

This has led to several S878 abends and hang conditions occurring with the controller, ultimately leading to delays in the critical batch process and causing significant service disruptions.

One recommendation made in order to relieve these storage contraints, was the exploitation of data spaces. This is indeed what we are already doing.

However, given the complexity and nesting dependencies between multiple jobs, this is not sufficient to alleviate our existing storage constraints.

In addition, we would also like to request that this addressing mode requirement be implemented for WAPL too.

Exploiting 64-bit addressing mode within zWS will allow us to further expand our batch capabilities without facing the current storage constraints.

    We do not plan currently to support 64bits addressing also because we believe it's not needed. A correct configuration and appropriate evaluation of the workload manageable by one Controller, with the option of splitting on two Controllers, provides a better functioning of the product overall besides avoiding 878 abends.
