Support for IMS Large Data Service

When dealing with an IMS Service message with a length greater than 32k, it seems that there is no need to use a Large Data Service and an IMS service can always be used as it accounts for this. However, a flag that gives the option of z/OS Connect not adding or removing header fields from the message when the copybook is greater than 32k will ensure that the process for generating these is consistent regardless of the size of the message. It will also ensure that an amendment to a copybook that takes it over or under the 32k threshold would not require a change to the mainframe program to cater for the addition or removal of the header fields by z/OS Connect.

    This requirement is addressed by z/OS Connect Enterprise Edition V3.0.38 / APAR PH29265:
    https://www.ibm.com/support/pages/apar/PH29265
    and API toolkit to 3.0.8.7/3.2.8.7:
    https://ibm.github.io/mainframe-downloads/eclipse-tools.html

    The z/OS Connect EE API toolkit and server runtime have been enhanced to support COBOL and PL/I data structures for IMS messages longer than 32K and have LL, ZZ, and TRANCODE fields in the request data structure, and have LL and ZZ fields in the response data structure.

    For further details about how to handle LLZZ and TRANCODE fields for IMS large data structures, refer to the “Service-level data conversion customization” topic in the z/OS Connect EE V3.0 Knowledge Center:
