DB2 Universal language interface (DSNULI) and CICS programs

  • 1.  DB2 Universal language interface (DSNULI) and CICS programs

    The DSNULI stub has entry points for IMS/DLI, such as CBLTDLI.  Those always appear to branch to the "batch" version of the IMS interface (specifically, module DFSLI000 in the IMS SDFSRESL library).  Is this working as designed?  I'd like it to, when the application is running within a CICS environment, branch to the CICS versions (DFHDLIAI from CICS SDFHLOAD library).  Since DFSLI000 is specifically mentioned in the doc page (https://www.ibm.com/docs/en/db2-for-zos/12.0.0?topic=program-universal-language-interface-dsnuli) and SDFHLOAD is not I must assume this is "working as designed", but maybe because no one thought to include CICS in the design.  Anyway, I don't know if I should open the issue as a bug or as a feature request.  Thoughts?

    I guess I should mention that it is only IMS calls using DSNULI that are not working.  DB2 "calls" work fine, in both batch and CICS environments.
