Tailoring GDDM for QMF and CICS

Before you install QMF, GDDM must be fully installed, tailored, and tested. It is important to do a complete GDDM installation and not merely restore to a library. During QMF installation, QMF modifies GDDM's ADDMF file. Additionally, you must define GDDM resources, such as programs and transactions, to CICS.

Changing GDDM Version 2.3 default parameters

If you are using GDDM Version 2.3, you might need to modify a parameter in the GDDM external defaults module. Ensure that the IOSYNCH parameter in ADMADFC is set to YES.

Run the installation verification procedure (IVP) for GDDM

Check that you have GDDM properly installed by running the IVP for GDDM. The IVP minimizes installation problems and ensures that you are installing QMF onto a clean system.
