Action Required (CICS/Link Pack Area): New runtime library modules for Automatic Binary Optimizer for z/OS (ABO) V1.1

News


Abstract

New Automatic Binary Optimizer for z/OS (ABO) V1.1 library modules are added with the current PTF, UI34924(V2R1) / UI33525(V2R2). These modules are contained in the Language Environment®(LE) SCEERUN data set.

Description of the new modules and the corresponding required setup:

Link pack area

z/OS V2R2 Language Environment Customization book, Appendix C (Table 30), provides the list of COBOL modules eligible for inclusion in the link pack area and the extended link pack area. Please be aware that the following list of additional ABO modules have been added to this table as per PTF UI34924(V2R1) / UI33525(V2R2) content:

ABO

  • Module Name   Description                       RMODE
    ------------------------------------------------------------
    IGZOLPA       ABO Library Service 1             ANY
    IGZOLPB       ABO Library Service 2             ANY
    IGZOLPC       ABO Library Service 3             ANY
    ------------------------------------------------------------

CICS

Typically, setting up CICS involves updating the CICS System Definition (CSD) file, which defines the program modules that are used under CICS. ABO V1.1 requires the runtime library modules listed below

  • IGZOLPA
    IGZOLPB
    IGZOLPC





  •  
If the CICS system autoinstall function is in use, then no update to the (CSD) file is needed. Otherwise, you can use the following DEFINE lines to define the runtime library modules that are required by ABO V1.1+ under CICS.

  • DEFINE PROGRAM(IGZOLPA) GROUP(CEE)
    DEFINE PROGRAM(IGZOLPB) GROUP(CEE)
    DEFINE PROGRAM(IGZOLPC) GROUP(CEE)


You can also add the following lines that are marked "new" to your existing CSD definition if you already have a CSD setup to run COBOL V3 and V4 programs.

  • DEFINE PROGRAM(IGZOLPA) GROUP(CEE)  <-- new
    DEFINE PROGRAM(IGZOLPB) GROUP(CEE)  <-- new
    DEFINE PROGRAM(IGZOLPC) GROUP(CEE)  <-- new


Alternatively you can use the member CEECCSD in the SCEESAMP sample dataset to do the setup. Verify that required LE PTF (below) is applied prior to using member CEECCSD:
 
  • UI34924 - HLE7790 (V2R1)
    UI32944 - HLE77A0 (V2R2)
