Log manager domain sample exit program: DFH$LGLS

DFH$LGLS is a sample global user exit program for the XLGSTRM exit point. It shows you how to change parameters such as the model log stream name that is used by the MVS system logger when it creates a new log stream dynamically.

About DFH$LGLS

DFH$LGLS shows you how to access and change some of the parameters that are passed to an XLGSTRM exit program.

Specifically, the program performs the following processing:

Changes the model log stream name pointed to by the UEPMLSN exit-specific parameter.
Uses the IXGINVNT macro to change the value of the HIGHOFFLOAD parameter in the log stream definition parameter list pointed to by the UEPIXG exit-specific parameter.

Prerequisites for DFH$LGLS

To run the sample program “as is”, you must first create a model log stream called CICSAD01.DEPT0001.MODEL100. However, you will probably want to tailor the sample to suit your own environment. The code contains comments to help you do this.
